Öğe Associated brain anomalies and clinical findings in corpus callosum dysgenesis(2003) Alkan A.; Kutlu R.; Baysal T.; Sigirci A.; Altinok T.; Orkan I.; Hallaç T.PURPOSE: The aim of this study was to evaluate the relationship between the types of the corpus callosum dysgenesis, the associated brain anomalies and clinical findings. MATERIALS AND METHODS: We analyzed the MR imaging findings in 169 patients with callosal dysgenesis. Corpus callosum dysgenesis was categorized into agenesis, hypogenesis and hypoplasia. The associated brain anomalies and clinical findings were evaluated. RESULTS: Associated brain anomalies were observed in 148 patients (87.5%). Twenty-one patients (12.4%) had isolated corpus callosum dysgenesis. Dysgenesis included agenesis in 22 (%13), hypogenesis in 46 (27.2%), and hypoplasia in 101 (59.7%) patients. The clinical findings were most commonly observed in patients with hypoplasia. CONCLUSION: The presence of corpus callosum dysgenesis is a strong indication of possible associated brain anomalies. Corpus callosum dysgenesis and associated brain anomalies should be investigated in children with developmental delay, seizures and microcephaly.Öğe Case report: Seronegative spondyloarthropathy in FMF: Accompaniment or manifestation?(2005) Baysal Ö.; Baysal T.; Altay Z.; Öner T.The arthritis of Familial Mediterranean Fever (FMF) is characterized either by repeated attacks of synovitis and polyserositis of short duration or, less commonly, by protracted monoarthritis that may persist for many weeks or months. Sacroiliac joint involvement in FMF is reported to be rare and limited to a few number of series. It is still controversial that seronegative spondyloarthropathy (SNSA) seen in FMF indicates a SNSA being musculoskeletal component of FMF or just an accompaniment. We present a FMF case who had protracted arthritis, inflammatory back pain and sacroiliitis refractory to colchicine treatment. The findings of the patient could only be relieved by spesific SNSA treatment suggesting that SNSA may be a manifestation of FMF.Öğe Celiac ganglion blockade: the effectiveness of CT guided percutaneous anterior approach(2003) Alkan A.; Durak A.C.; Ozcan N.; Kutlu R.; Baysal T.; Sigirci A.PURPOSE: To investigate the effectiveness and safety of celiac ganglion blockade in cases with abdominal malignancies who are narcotic analgesic dependent for control of severe abdominal pain. MATERIALS AND METHODS: A total of 30 celiac ganglion blockades were performed in 27 patients between the ages of 19 and 75. A 22 G Chiba needle was placed through the percutaneous anterior approach into the celiac ganglion region under the guidance of CT, and 98% alcohol was administered. The procedure was repeated in three cases due to insufficient response. RESULTS: In 24 (88.8%) of the 27 cases, the severity of pain decreased. Total relief of the pain was achieved in 13 (48.1%) cases. In 9 (33.3%) cases pain was controlled with non-narcotic analgesics. In 2 (7.4%) cases, the dose of the narcotic analgesic decreased. There was no change in the severity of the pain in 3 (11.1%) cases. Transient complications were diarrhea in 4 (14.8%), hypotension in 6 (22.2%) cases and hemiparesis in one (3.7%) case. CONCLUSION: Celiac ganglion blockade through the percutaneous anterior approach under the guidance of CT should be preferred for the control of pain in the early periods in cases with abdominal malignancies, especially gastric and pancreatic, due to easy performance, safety, lower incidence of complications, high success rate and low cost.Öğe Computed tomography guided percutaneous nephrostomy(2003) Baysal T.; Soylu A.; Saraç K.; Alkan A.; Dusak A.; Sarier M.Objectives: We investigated the value of computed tomography guided nephrostomies'in patients with absent or minimal pelvicaliceal dilatation and with different kidney anatomy and localization without using ultrasound and fluoroscopy. Material and Methods: We attempted 48 computed tomography guided nephrostomy placements in 40 patients. Both puncture of collecting system and placement of the catheters were made under computed tomography guidance. The Seldinger method was used in all procedures. Results: Percutaneous nephrostomies were successfully achieved in all patients without major complications. There were minimal dilatation of the pelvicaliceal systems in 28 (58.3%) of 48 nephrostomies. Four patients had obesity, and another 4 had rotation anomaly. One patient had both ectopic located and malrotated kidney. One patient had subcapsular haematoma and another one had retrorenal colon variation. Eighteen of the percutaneous nephrostomies were made intercostally. Single puncture was used in 35 (73%) and twice puncture were used in 13 (27%) procedures. The time necessary for the procedure ranged from 17-36 min (mean 28 min). Conclusion: Computed tomography guided percutaneous nephrostomy is a safe method with low rate of complications especially in patients with obesity, without pelvicaliceal dilatation or with minimal dilatation and patients with ectopic, malrotated kidneys and retrorenal colon variations.Öğe Conjoined lumbosacral nerve roots: Report of two cases(Turkish Neurosurgical Society, 1995) Akbasak A.; Biliciler B.; Vatansever M.; Baysal T.; Toksoz M.Conjoined origin anomalies of lumbosacral nerve roots, if incorrectly interpreted, could be misdiagnosed as disc herniations on computed tomography (CT) and myelography. Anomalous L-5 and S-1 nerve roots appear infrequently. An underlying herniated disc may not be diagnosed because of unique anatomical changes. If not properly recognized, surgery for entrapment disorders may result in serious neural injury because of an improper surgical approach in exposure and removal of the underlying herniated disc. In this paper, we present two cases with such anomalies.Öğe Effects of testicular microlithiasis on Doppler parameters: Report ofthreecases(BioMed Central Ltd., 2002) Kutlu R.; Sigirci A.; Baysal T.; Alkan A.; Sarac K.Background: Testicular microlithiasis is a rare, usually asymptomatic, non-progressive disease of the testes associated with various genetic anomalies, infertility and testicular tumors. According to our literature search, there is no specific data about Doppler findings in this disease. Case presentation: Doppler findings of three cases of testicular microlithiasis during last two years in our institution are presented. Conclusions: Although our hypothesis was to find increased Doppler parameters due to intratesticular arterial compression, our findings suggest that there are no Doppler findings specific to testicular microlithiasis.Öğe An en-plaque tentorial lesion in a pregnant woman: Follow-up with MRI (2003:2a)(2003) Alkan A.; Parlak M.; Baysal T.; Sigirci A.; Kutlu R.; Altinok T.[No abstract available]Öğe En-plaque tuberculomas of tentorium in a pregnant woman: Follow-up with MRI (2003:2b)(Springer Verlag, 2003) Alkan A.; Parlak M.; Baysal T.; Sigirci A.; Kutlu R.; Altinok T.En-plaque tuberculoma is a rare manifestation of CNS tuberculosis and presents as a solitary, focal, caseous plaque-like lesion. It is difficult to differentiate en-plaque like meningeal tuberculoma from true primary or secondary meningeal neoplasia. Good response to antituberculosis treatment in a patient with tuberculosis history and typical MR findings confirm the diagnosis. We present the follow-up MR imaging findings of a case in which an en-plaque tuberculoma on tentorium was diagnosed during pregnancy in a patient with a history of tuberculosis. To the best of our knowledge, en-plaque tuberculomas of tentorium during pregnancy have not been reported before.Öğe Endovascular treatment of huge saccular abdominal aortic aneurysm in a young Behcet patient: Mid-term result(2002) Kutlu R.; Gulcan O.; Akbulut A.; Turkoz R.; Baysal T.Background: Abdominal aortic aneurysm formation is among the arterial complications of Behcet's disease. Weakness and fragility of aortic walls leads to the development of arterial complications like pseudoaneurysms. Case Presentation: A case of huge saccular abdominal aortic aneurysm in a young Behcet patient who was successfully treated with endovascular stent graft placement is reported, diagnostic and interventional procedures are discussed, and mid-term follow-up results are presented. Conclusions: Endovascular treatment of abdominal aortic aneurysm complications of young Behcet patients who are not suitable for open surgery and need intervention could be an alternative treatment modality even without performing preprocedural angiography. © 2002 Kutlu et al; licensee BioMed Central Ltd.Öğe Isolated inguinal bladder hernia izole inguinal mesane hernisi(2010) Baysal T.; Soylu A.; Erdogan O.Isolated urinary bladder herniation into the inguinal canal is rare. It is often diagnosed intraoperative? during surgery or is identified after intraoperative injury. Early diagnosis with radiologic imaging is important to avoid complications during repair surgery. Computed tomography seems the best imaging choice to outline the details of herniation. We report an incidentally discovered case of inguinal bladder herniation with intravenous pyelography and computed tomography findings. © Medical Journal of Trakya University.

Aims: To detect metabolic changes in the cerebellar and cerebral normal appearing white matter with single-voxel H-MR spectroscopy (MRS) in patients with lung cancer. Methods and material: MRS was performed in the Cerebellar White Matter (CWM) and Parietal White Matter (PWM) of patients with lung cancer (n=38; age range: 44-82 y; mean age: 66.1 ± 8.7) and an age-matched control group (n=32; age range: 42-80 y; mean age: 62.9 ± 8). Biopsies of lung masses showed 25 Non-Small Cell Lung Cancer (NSCLC) and 13 Small Cell Lung Cancer (SCLC). NAA/Cr, NAA/Cho and Cho/Cr ratios were calculated. Statistical analysis used: The unpaired-t test was used for the assessment of metabolite ratio differences between patients and control subjects. Mann-Whitney U test was used among SCLC, NSCLC, and control group for the evaluation of metabolite ratio differences. Results: The Cho/Cr ratios in the CWM were significantly lower in the patients compared to controls (p=0.03). The Cho/Cr ratio of patients with SCLC was significantly lower in PWM than both NSCLC (p=0.02) and control group (p=0.03). Conclusion: Decreased Cho/Cr ratio possibly represents increased uptake of Cho or reduced brain function. These results may be important in assessing patients with lung cancer in order to help with treatment planning and prognosis. © 2017, Scientific Publishers of India, All rights reserved.Öğe MR spectroscopy in the differential diagnosis of focal brain lesions in neurofibromatosis type 1 patients(2003) Alkan A.; Kutlu R.; Sigirci A.; Baysal T.; Altinok T.; Dusak A.; Saraç K.PURPOSE: To determine the role of MR spectroscopy in the differential diagnosis of focal brain lesions in neurofibromatosis type 1. MATERIALS AND METHODS: Fifteen patients with neurofibromatosis type 1 were evaluated by routine MRI and single voxel MR spectroscopy (TE: 31). The posterior parietal white matter of 20 age-matched healthy volunteers constituted the control group. NAA/Cr, Cho/Cr and MI/Cr ratios were calculated and compared with the control group. RESULTS: A total of 58 focal brain lesions were detected by MR imaging. When patients with hamartomas and gliomas were compared with the control group, a decrease in the NAA/Cr ratio, and a significant increase in Cho/Cr and MI/Cr ratios were found. The decrease in the NAA/Cr ratio and the increase in Cho/Cr and MI/Cr ratios of gliomas were significant when compared with hamartomas. With MRI and MR spectroscopy findings, 52 hamartomas and 6 gliomas were detected. CONCLUSION: Since MR spectroscopy has the ability to detect cellular metabolic changes, it could provide additional information to MR imaging about the differential diagnosis and treatment planning of focal parenchymal lesions in neurofibromatosis type 1.Öğe Postintubation tracheal rupture(2001) Kutlu R.; Kuzucu A.; Soysal Ö.; Baysal T.; Karaman I.; Akbulut A.Tracheal rupture following endotracheal intubation is an extremely rare emergency that needs expedient diagnosis and treatment. The clinical and radiological features of postintubation tracheal rupture in a 45-year-old woman who underwent vertebral stabilization are described. Primary suture closure was performed successfully via a cervical approach. © 2001 SAGE Publications.Öğe Reversible posterior leukoencephalophaty in a child with acute glomerulonephritis: Follow-up MR imaging(2003) Alkan A.; Kutlu R.; Baysal T.; Si?irci A.; Sönmezgöz E.; Yakinci C.Hypertensive encephalopathy is the most common cause of reversible posterior leukoencephalopathy syndrome, which is quite rare in the pediatric age group. Diffuse vasogenic edema in the posterior circulation territories at the initial stages and complete disappearance of edema on follow-up imaging is the characteristic feature of this syndrome. Frontal and temporal lobe involvement is rarely seen. In this report we present the follow-up MR and diffusion weighted imaging findings of reversible posterior leukoencephalopathy syndrome in a pediatric case with this rare involvement in addition to characteristic involvement localization.Öğe An unusual complication of ventriculo-peritoneal shunt: Cerebrospinal fluid cyst in liver(Elsevier BV, 2004) Koçak A.; Baysal T.; Çayli S.R.; Ateş Ö.; Önal Ç.Internal drainage of cerebrospinal fluid (CSF) to the abdominal cavity via ventriculo-peritoneal (VP) shunt is commonly used for the treatment of hydrocephalus. Many types of shunt systems are available, but all are liable to complication. Some of these complications occur frequently and are therefore well known. However, there are other complications which occur rarely, including cerebrospinal fluid cyst in liver. We report a 15-year-old female who developed a CSF cyst in the liver due to mislocation of the peritoneal catheter which was successfully treated by simple repositioning. © 2004 Elsevier Ireland Ltd.

In thirty one rheumatoid arthritis patients (26 women and 5 men) dominant hand conventional radiographs magnified with a hand lens and direct magnified radiographs (1.5X) using the standart magnification equipment of the mammography unit were compared. A scoring system was used in the evaluation of erosive changes and joint space narrowings. Total scores of both erosions (p<0.0001) and joint space narrowing (p<0.02) were significantly higher in direct magnification radiographs compared to optically magnified conventional radiographs. In early rheumatoid patients, with a disease duration of less than one year, total score of erosions was significantly higher in direct magnification technique compared to optical magnification technique (p<0.001). Our findings revealed that, direct magnification radiographs obtained using standart magnification equipment of the mammographv unit were superior to opticallv magnified conventional radiographs in demonstrating erosive changes particularly in the hands and wrists of patients with early rheumatoid arthritis.
