Cavernous angioma of the second cranial nerve and chiasmatic apoplexy

Abstract:

We present the case of a female patient who developed chiasmatic apoplexy and menstrual alterations. CT scanning showed a suprasellar hemorrhage. She underwent surgery with the presumptive diagnosis of pituitary tumor. At surgery, we find a brown-grayish lesion involving left optic nerve and chiasm. Cavernous angioma was diagnosed by histopathology. Cavernous angiomas constitute nearly 15% of all central nervous system vascular malformations. Location at the optic pathway is very rare, but must to be ruled out in the diagnosis of a patient with chiasmatic and/or optic apoplexy. Surgery is useful in preventing worsening of the previous deficit or a new visual defect.
