Bilateral acquired inflammatory Brown's syndrome.

An 11-year-old boy presented with fever, skin rash, joint pains and vertical diplopia, and was found to have a right Brown's syndrome and systemic onset Juvenile Rheumatoid Arthritis (JRA). Later in the course of his illness, he developed a left Brown's syndrome. Acquired Brown's syndrome may occur as a complication of JRA during exacerbations of the systemic inflammatory disease.
