Weber syndrome secondary to brain stem tuberculoma

ABSTRACT

This case report describes a rare presentation of presumed brain stem tuberculoma in a 28-year-old male who presented with acute onset of third cranial nerve palsy with contralateral hemiparesis (Weber syndrome) and upgaze palsy. Isolated midbrain tuberculoma is rare, presenting with varied clinical manifestations and radiological findings posing as a diagnostic dilemma. Weber syndrome is commonly caused by midbrain infarct secondary to occlusion of branches of the posterior cerebral artery and rarely from a tuberculoma. The patient is a case of disseminated tuberculosis with granuloma in midbrain causing pressure effect, thereby presenting with features consistent with Weber syndrome and upgaze palsy. The patient had good recovery with antitubercular treatment and systemic steroids.
