Tuberculoma of the brain is an important clinical entity. The main challenge in the management of brain tuberculoma is its diagnosis. Appearance in computed tomography (CT) scan of brain is common and consists of solitary or multiple ring-enhancing lesions with moderate perilesional edema, but these are not specific for tuberculoma as neurocysticercosis (NCC), coccidiomycosis, toxoplasmosis, metastasis and few other diseases may also have similar appearance on CT scan brain. Cerebrospinal fluid examination is often normal and biopsy and tissue culture from the lesion though the diagnosis of choice is technically too demanding and not feasible in most of the times. All these put the clinicians in a great dilemma as regard to a confidant diagnosis of tuberculoma of the brain. With advancement of imaging techniques, magnetic resonance imaging (MRI) of brain with magnetic resonance spectroscopy (MRS) has shown a great hope in this context as MRS shows a specific lipid peak in cases of tuberculoma which is not seen in any other differential diagnoses of tuberculoma. This review article is written to have an overview regarding the current diagnostic approach for brain tuberculoma with special emphasis on the role of MRS. Extensive literature review of the articles published in English was conducted using Google search, Google Scholar, PubMed and Medline using the keywords such as ring-enhancing lesions, etiology, tuberculoma, NCC, CT scan brain, MRI, MRS, images.
