Brain Tuberculoma as a Differential Diagnosis of Single Intracranial Lesion: Case Report

ABSTRACT

Tuberculosis (TB) of the central nervous system (CNS) is considered one of the most severe forms of presentation of the disease. Although only 1% of TB cases involve the CNS, these cases represent around between 5 and 15% of extrapulmonary forms.1,2 Tuberculous meningitis (TBM) is the most frequent form of CNS TB. The granulomas formed in the cerebral tuberculoma may cause hydrocephalus and other symptoms indicative of a CNS mass lesion. In the absence of active TB or TBM, the symptoms may be interpreted as indicative of tumors.3,4 The prognosis is directly related to the early diagnosis and proper treatment installation.5 We report the case of a patient with intracranial hypertension syndrome, expansive mass in the parieto-occipital region, accompanied by a lesion in the rib, initially thought to be a metastatic lesion, although posteriorly diagnosed as a cerebral tuberculoma.
