[Optochiasmatic tuberculoma: complication of tuberculous meningitis. Report of a case and review of the literature]

Abstract

Optochiasmatic tuberculomas are rare and have a poor prognosis if not diagnosed early and treated adequately. We report the case of 4-year-old boy who presented a chiasmatic tuberculoma after tuberculous meningitis revealed by progressive visual failure. Cerebral gadolinium enhanced magnetic resonance imaging demonstrated a chiasmatic and a brainstem ringlike enhancing lesions. Outcome was favorable with antituberculosis therapy and corticosteroids. Are recalled the diagnostic aspects, notably the neuroradiological findings, in this particular localisation of tuberculosis with a review of the similar thirty-three cases reported in the literature.
