Abstract

PURPOSE
To report a case of pituitary apoplexy presenting as isolated bilateral oculomotor nerve palsy.
CASE SUMMARY
A 46-year-old male presented with bilateral ptosis and acute severe headaches for 6 days. He underwent head surgery and bilateral vitrectomy 12 years prior to his visit because of ocular and head trauma. He mentioned that previous visual acuities in both eyes were not good. The initial corrected visual acuity was finger counting in the right eye and 20/500 in the left eye. Ocular motility testing revealed the limitation of adduction, supraduction, and infraduction with complete bilateral ptosis in both eyes, and his left pupil was dilated. He was diagnosed with an isolated bilateral oculomotor nerve palsy. Magnetic resonance imaging indicated pituitary gland hemorrhage with a tumor, which was suspicious of pituitary apoplexy. The patient was treated intravenous with 1.0 g methylprednisolone to prevent the corticotropic deficiency. In addition, he underwent surgical decompression using a navigation-guided transsphenoidal approach and aspiration biopsy. He was confirmed with pituitary adenoma using a pathological examination. The patient's ocular movements began to dramatically improve by the third day postoperatively. At 4 months postoperative follow-up, his ocular movement and double vision were completely recovered.
CONCLUSIONS
This was a rare case of pituitary apoplexy with bilateral isolated oculomotor nerve palsy, which was the first report in the Republic of Korea. A full recovery was achieved after early surgical treatment.
