Clinical introduction

A 59-year-old woman with poorly controlled hypertension emergently presented for sudden onset right eyelid drooping for 1 day. She complained of diplopia on left gaze and dull right periorbital pain. Intermittent throbbing headache was also noted. Earlier on the day of presentation, she visited another hospital where non-contrast cranial CT read as negative.

On physical examination, severe right-sided ptosis (8 mm), mydriasis (5 mm) with sluggish reaction to light and a downward, lateral deviation of the right eye (figure 1) were observed. She had intact muscular strength and normoreflexia.
