    Incidental findings on cranial CT scans of children with head trauma
    (2019) Yilmaz, Ali; Altas, Hilal
    Aim: The aim of our study was to determine the prevalence of incidental findings in healthy pediatric age group who were taken to CT for head trauma. Material and Methods: Cranial CT of 980 pediatric patients who were presented to the emergency department of our hospital due to brain trauma were retrospectively reviewed. All cranial CT scans were interpreted by a faculty radiologists and a neurosurgeon. All traumatic and non-traumatic CT findings were identified and entered into two seperate databases. Results: Nine hundered eighty head-injured children who received cranial CT scans in the ED were evaluated. According to exclusion criteria, 146 of all were eliminated from the study. Of all remaining 834 patients, total of 86 patients (% 10.3) had IF on their CT scans. The 86 patients with incidental findings had a median age of 6.8 years (1 week –17.4 years old ). Intracranial calcification was the most common incidental lesion in 14 patients (1.6%) while the least frequent one was the open lip schizencephaly in 2 patients (% 0.23). Malignant lesions such as astrocytoma-diffuse glioma in 4 patients (0.47%) and potentially life-threating lesions like arteriovenous malformation in 2 patients (0.23%) were also detected. Conclusion: In pediatric age group who have long life expectancy, medicolegally and ethically it is important to determine incidental findings and specify them at radiological reports. It is necessary to disclose the incidental findings to the patients and families in an appropriate manner in order to decrease anxiety.

    Magnetic resonance imaging of the lumbar spine in adult: Evaluation of spinal incidental findings in patients with low back pain
    (2019) Altas, Hilal; Yilmaz, Ali
    Aim: We aimed to incidental findings discovered in patients with suspected low back pain disease undergoing MRI of the lumbar spine and the clinical importance of those findings. Material and Methods: One thousand seven hundred fourteen patients included who were admitted to our hospital with a preliminary diagnosis of low back pain were examined. The duration of low back pain complaints of the patients was ranging from 1 week to 4 years. MRI examinations were interpreted by academic neuroradiologists who had 7 years of experience, at the time of the study. Results: Overall, 358 patients (20.9%) had incidental findings. Transitional vertebrae was the most common (134 cases, 7.8%) incidental finding, followed by vertebral hemangioma (65 cases, 3.8%) and Tarlov cyst (54 cases, 3.2%). The incidence of fatty filum terminale, compact bone island, spina bifida, synovial cyst and sacral meningocele was 2.1%, 1.5%, 1%, 0.8% and 0.7% respectively. Of these 1714 patients, 329 patients (92.06%) had one finding, 22 patients (5.95%) had two findings, and 7 patient (1.98%) had three findings. The conus medullaris was terminated in 1710 (99.7%) of the patients (L1-2) .This level were considered normal. In four cases, the spinal cord was determined to be below the required level. The prevalence of transitional vertebra was 7.8%. The prevalence of sacralization and lumbalization was 5.1% and 2.7%, respectively. Conclusion: In this study we showed that incidental findings are mostly benign but interestingly there were no malignant or potentially malignant incidental lesions.
