Abstract

Background: Tuberculosis of the central nervous system is an uncommon but one of the most severe forms. It manifests as tuberculoma and tuberculous meningitis, with the majority of cases affecting children and immunocompromised patients. Overall, tuberculomas make up to 0.15–2 % of all intracranial lesions but sellar tuberculoma is extremely rare.

The Case: An 18-year-old female patient presented with complaint of generalized weakness, eye pain and headache for 3-4 months. Magnetic resonance imaging (MRI) of brain showed sellar and suprasellar space occupying lesion. Trans sphenoidal approach was used to remove the lesion completely. A sellar tuberculoma was confirmed on pathological evaluation and the patient was put on postoperative anti-tubercular therapy.

Conclusion: Although rare, intracranial tuberculomas, particularly those that originate in the sellar, are notorious for mimicking pituitary tumors by jeopardizing pituitary hormonal function and applying compressive forces on surrounding intracranial structures. However, a prompt assessment can help overcome this diagnostic difficulty with the timely initiation of anti-tubercular therapy (ATT).

The image titled "MRI Brain Coronal Study Showing Sellar Mass with Suprasellar Extension Causing Optic Chiasm Compression" presents a coronal MRI scan that reveals a mass in the sellar region, extending into the suprasellar area. The red arrow points to the lesion compressing the optic chiasm, a critical structure responsible for vision. This finding is consistent with the diagnosis of a sellar tuberculoma, a rare condition that can mimic pituitary tumors, leading to both visual disturbances and hormonal dysfunction​.
