title: Osteochondroma of the trochlea presenting as acquired Brown syndrome: a case report.
abstract: The following is a rare observational case report of a 16-year-old boy who presented with acquired Brown syndrome associated with a painless slowly growing mass in the supranasal area of the left eye. Meticulous surgical removal of the mass resulted in recovery of superior oblique muscle function. Histopathology was consistent with osteochondroma of the trochlea. To the knowledge of the authors, this is the first reported case of osteochondroma of the trochlea causing acquired Brown syndrome.
