Acute manifestation of LHON and coincidental finding of a pituitary adenoma: a case report.

Abstract

A patient with Leber Hereditary Opticus Neuropathy (LHON) and a pituitary adenoma is presented. The different ophthalmological signs of LHON are described and illustrated. A definite diagnosis is made by detecting a mitochondrial mutation. A radiological examination revealed a pituitary adenoma. The pituitary adenoma may be a trigger factor in the penetrance of LHON.
