The neuroradiological findings in a case of cerebral tuberculoma

Abstract

This paper describes the neuroradioloigical findings in a case of cerebral tuberculoma. Computed tomography demonstrated a mass in contact with the cranial bone with marked contrast enhancement and accompanied by perifocal cerebral edema. External carotid angiography revealed a homogenous stain supplied from the middle meningeal artery. Furthermore, by radioisotope scan it appeared to be a region of increased uptake with a comparatively clear border and was thereby misdiagnosed as meningioma.

Tuberculoma Mimicking Falx Meningioma-Case Report-

“…Angiography may show vascularization of the mass, which is supplied by branches of the middle meningeal artery. 2,4,9,10) One feature that differentiates tuberculoma from others is the isointensity and marked perifocal edema on T 2 -weighted images. 10) The differential diagnosis includes metastatic brain tumor, brain abscess, malignant lymphoma, and granuloma.…”

Atypical meningeal lesion

“…Meningeal tuberculomas, as reported here, are rarer, with only 12 cases reported in the English literature. [2][3][4][5][6][7][8][9][10][11][12] Diagnosis of both intraparenchymal and extra-axial tuberculomas radiologically is often difficult, with cases commonly misdiagnosed initially as a neoplasm. en-plaque meningiomas.…”
