Abstract

We report the case of a 52-year-old woman who developed vertical diplopia of 1-days duration. Neuro-ophthalmological testing revealed left trochlear nerve palsy, and sellar MRI revealed a 1.5 cm-sized pituitary mass lesion, a Rathke's cleft cyst. The diplopia disappeared spontaneously after 6 days.

Keywords: Trochlear nerve, diplopia, transient palsy, isolated cranial nerve palsy, Rathke's cleft cyst, case report
