Choroid plexus tuberculoma: Diagnosis, management and role of endoscopy

Abstract

Ventricular involvement in central nervous system tuberculosis can be in the form of tuberculous ependymitis, intraventricular tuberculoma, intraventricular tuberculous abscess, choroid plexitis and choroid plexus tuberculoma. Only a few cases of choroid plexus tuberculomas have been described and even more rare is the description of the role of endoscopy in management of intraventricular tuberculomas. We report a 33-year-old patient while on treatment for tubercular meningitis who developed a left side choroid plexus lesion with loculated temporal horn. To confirm the diagnosis, endoscopic biopsy of the lesion was carried out. The final histopathology was tuberculoma. Intraventricular tuberculomas are usually associated with recalcitrant lesions, probably due to the poor drug levels within the CSF or as an indirect effect of immune resistance and biopsy becomes important to rule out other possibilities.
