Many types of neurotuberculosis have been described, but there is only one previously reported case of subdural empyema caused by tuberculous bacilli. A 1-year-old boy who had been treated for pulmonary tuberculosis was referred to the authors' institution with a diagnosis of right frontoparietal extraaxial abscess formation. Computerized tomography and magnetic resonance imaging revealed an extraaxial abscess with no evidence of calvarial infection. A craniotomy was performed to drain the pus, which was located subdurally. A polymerase chain reaction test yielded positive results, and histopathological examination revealed caseation. Antituberculous treatment was started after a diagnosis of subdural empyema with related neurotuberculosis had been made. At the end of a 12-month course of medical therapy, the patient was well with no evidence of tuberculosis.eninfo:eu-repo/semantics/closedAccessEmpyemaNeurotuberculosisSubdural spaceArticle9469889911140953010.3171/jns.2001.94.6.09882-s2.0-0034877314Q1
