ABSTRACT Background: Tuberculosis can present in the central nervous system as tuberculous meningitis, tuberculomas, abscesses, and spinal arachnoiditis. Tuberculomas occur in only 1% of all central nervous system tuberculosis cases. Their occurrence in the posterior fossa is extremely rare. Case report: A previously healthy young male patient presented with a history of headache, nausea, and blurred vision. Neuroimaging revealed a mass present in the fourth ventricle. The lesion was successfully resected. Histological and microbiological findings suggested the presence of a tuberculoma. Conclusion: Tuberculomas can be found in the posterior fossa in adults. This infectious pathology should not be forsaken when considering the differential diagnosis for infratentorial masses.
