RAMIREZ, Mónica; CORTES, Eduardo; BETANCUR, José  y  GARCES, Carlos. Cerebral tuberculosis without meningitis in a immunocompetent child. Rev. chil. infectol. [online]. 2018, vol.35, n.2, pp.207-212. ISSN 0716-1018.

Cerebral tuberculosis TB (tuberculomas) without meningitis is an uncommon disease with a high morbidity and mortality. We report on a case that illustrates the complexity of this clinical presentation. An 11 month old, previously healthy male infant was brought to the clinic due to fever present during the last 1.5 months, associated with loss of neurodevelopmental goals and signs of endocranial hypertension. CT scan of the skull revealed dilatation of the ventricular system with transependimary edema; MRI showed multiple intra- and extra-axial micronodular images and hydrocephalus. Studies of CSF (cyto-chemical analysis, staining, culture for aerobes, fungi, mycobacteria, and molecular tests for TB were negative). Empirical management for subacute meningoencephalitis was prescribed complemented with tetraconjugated treatment for TB and steroids. As there was no microbiological isolation, biopsy of a cerebellar lesion was performed, which revealed chronic necrotizing granulomatous inflammation and acid-alcohol resistant bacilli. The diagnosis of cerebral TB without meningeal involvement was confirmed. The objective of the present report is to emphasize the importance of considering this presentation of TB in children, to remark the need of exhaustive search for the etiologic agent by obtaining samples of the different fluids and tissues even if it implies recurring to invasive methods.
