Central nervous system (CNS) tuberculosis is one of the most devastating manifestations of tuberculosis and a leading cause of morbidity in developing countries. Its main pathological manifestations include meningoencephalitis, tuberculomas, and less frequently, abscesses. The involvement of ventricles is rare and the occurrence of intraventricular tuberculous abscess has been reported in literature only one time so far. Thus, without any specific clinical and radiological signs, the diagnosis of such condition can be very challenging. In this report, we describe the case of a ruptured tubercular abscess of the third ventricle in a 56-year-old man presenting with an atypical radiological image mistaken for a ventricular cystic tumor.
