Abstract

SANTOS-DITTO, R.A.; SANTOS-FRANCO, J.A.  and  PINOS-GAVILANES, M.W.. Cavernous angioma of the second cranial nerve and chiasmatic apoplexy. Neurocirugía [online]. 2007, vol.18, n.1, pp.47-51. ISSN 1130-1473.

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.

Keywords : Cavernous angioma; Chiasmatic apoplexy; Optic nerve.
