Brain CT and MRI Findings in 100 Consecutive Patients with Intracranial Tuberculoma

Abstract

Multiple tuberculomas and infratentorial locations were more common in the authors' patient population than in previous reports. The MRI signal characteristics of intracranial tuberculoma are extremely diverse. An isointense or hypointense core with a hyperintense rim on T2-weighted and FLAIR images is the most common presentation. Core hypointensity of lesions on these images is related to necrosis and the large number of cells.

Cerebral infarction and tuberculoma in central nervous system tuberculosis: frequency and prognostic implications

“…Prognosis of tuberculoma patients was good while cerebral infarcts led to poor prognosis. Previous studies have shown presence of tuberculoma in 16%–40% patients with TB meningitis 6 – 9. Tuberculoma most likely represents an immune response to tuberculous brain parenchymal infections.…”

Multiple lesions on CT brain scan: tuberculosis or neurocysticercosis?

“…The findings on this CT scan, which favour tuberculosis over NCC, are the irregularity of the shape of some of the nodular lesions, varying enhancement patterns, considerable peri-lesional oedema, and increased meningeal perivascular enhancement 3. The girl recovered fully with continued anti-tuberculous treatment and supplemental steroids.…”

Giant intracranial calcification associated with new onset focal seizure

“…Based on the child's medical history it was thought that the lesion could be consistent with a calcified parenchymal granulomata that can be seen in up to 20% of patients with a history of tuberculosis 1. However, the histological evaluation revealed a heterotopic ossification most consistent with a calcified cavernous angioma.…”
