This could be due to the misinterpretation of coagulative necrosis of glioblastoma multiforme as caseous necrosis of a tuberculoma
. One case of spinal astrocytoma was diagnosed as ependymoma on crush cytology, while one case each of cerebellopontine angle schwannoma and cerebellar hemangioblastoma were misinterpreted as meningioma and benign mesenchymal tumor, respectively [Table 3].
Most of these patients had mass lesions like tumor, neurocysticercosis, tuberculoma
, abscess or CVT.
cerebral computed tomography (CT brain) and cerebral magnetic resonance imaging (MRI brain) include: leptomeningeal enhancement, tuberculomas
, hydrocephalus, vasculitis and cerebral infarctions.

In our case, MRI of the liver revealed liver lesions with features suggestive of liver microabscess that are likely representing tuberculomas
Ultrasonography may facilitate the differentiation of tuberculomas
from malignant masses.

(i) Cystic masses: endothelial cyst, pseudocyst, and hydatid cyst (ii) Solid masses: adenoma, nodular hyperplasia, carcinoma, metastases, pheochromocytoma, neuroblastic tumors, neurofibroma, schwannoma, leiomyoma, angiosarcoma, hamartoma, tuberculoma
, and amyloidosis (iii) Fat-containing masses: lipoma and myelolipoma Modified from Arnaldi and Boscaro .
Oral lesions of tuberculosis may present as ulcer, nodule, fissure, tuberculoma
, or granuloma .
A diagnosis of CNS tuberculoma
without meningitis can be challenging because the clinical presentation is often vague, mild, or even asymptomatic.
