Tuberculoma Mimicking Falx Meningioma-Case Report-

Abstract

A 25-year-old male presented with an intracranial tuberculoma mimicking falx meningioma manifesting as right lower monoparesis. The patient had a past history of pulmonary tuberculosis, cured by antituberculous therapy. Computed tomography and magnetic resonance (MR) imaging showed a lesion mimicking a falx meningioma. Surgery achieved subtotal resection. Histological and biochemical examinations revealed the surgical specimen was tuberculoma. He was treated with antituberculous therapy, and his gait disturbance disappeared. Follow-up MR imaging showed no regrowth.

Giant cerebral tuberculoma in pregnancy: review of literature discussion

“…3 Cystic and en plaque meningioma mimics and those caused by M. avium have been mentioned in literature. [4][5][6][7] In our case the tuberculoma was located in right parieto occipital region and resembled a high grade neoplastic lesion.…”

“…Tuberculomas have been located in fronto parietal region, pontine, pericallosal location and suprasellar locations. 3,6 Though intraparenchymal tuberculomas are most common but dural based extracranial tuberculomas are reported. 3 Cystic and en plaque meningioma mimics and those caused by M. avium have been mentioned in literature.…”

Tuberculoma of the cavernous sinus mimicking a meningioma: Case report and review of the literature

“…In computed tomography scans, tuberculoma appears as a low or high density mass, round or mutilobular, with homogeneous or ring enhancement after contrast agent injection [3,12]. Most tuberculomas appear hypointense to isointense to gray matter [14][15][16][17][18][19] on T1WI and T2WI and variable on DWI, often with a hypointense rim in T2WI [20]; those with hyperintense centers on T2WI are usually hyperintense on DWI. [21] Meningiomas typically appear isointense to gray matter on T1WI and T2WI and DWI, unless atypical or aggressive.…”

Central nervous system tuberculosis mimicking tentorium meningioma: a rare case

“…It is important to be familiar with the fact that neurotuberculosis can mimic other diseases, such as meningiomas, which should be considered as differential diagnoses 3 .…”
