Abstract: With rising incidences of immunosuppression including HIV infection and various other factors, a resurgence of tuberculosis has been observed. We herewith describe two cases of posterior fossa tuberculomas with presentation mimicking mass lesions. Tuberculomas in the brain are not uncommon in the developing countries. Although they can mimic neoplastic lesions, the early diagnosis of tuberculous lesion with MRI and MR spectroscopy results in prompt institution of antituberculous therapy. Hypointensity in T2-weighted sequence with ring enhancement and the presence of a prominent lipid-lactate peak on MR spectroscopy is highly suggestive of the tuberculous nature of the lesion.
