Oculomotor nerve palsy may occur as a result of benign or malignant pathologies such as trauma, aneurysm and tumor. Ptosis, mydriasis and diplopia may be seen depending on the affected nerve fibers and nucleus. While visual field defects such as bitemporal hemianopsia usually were seen in the initial stages of the pituitary adenoma which may be important causes of the oculomotor nerve palsy, generally third cranial nerve palsy symptoms were seen in advanced stages. In this case report, the oculomotor nerve palsy which caused by pituitary adenomas were presented.

Okulomotor Sinire Bası Yapan Hipofiz Adenomunun Anatomik Olarak İncelenmesi

Öz

Okulomotor sinir felci travma, anevrizma, tümörler gibi benign veya malign olabilen patolojiler sonucunda gelişebilir.  Etkilenen çekirdeğe ve sinir liflerine bağlı olarak  pitozis, midriazis, diplopi görülebilir. Okulomotor sinir felcinin önemli nedenlerinden biri olabilen hipofiz adenomlarında genellikle başlangıçta bitemporal hemianopsi gibi görme defektleri görülürken genellikle ileri safhalarda üçüncü kranial sinir felci bulguları görülebilir. Bu olgu sunumunda, hipofiz adenomunun sebep olduğu okulomotor sinir felci sunuldu.
