A ­rare ­cause of ­acute vis­u­al ­loss due to a chi­as­mal cav­ern­ous mal­for­ma­tion is pre­sent­ed. Acute vis­u­al ­loss was due to ­local hem­or­rhage and vol­ume expan­sion of the cav­ern­ous mal­for­ma­tion ­inside and out­side of the ­optic chi­as­ma. This ­unique loca­tion of cav­ern­ous mal­for­ma­tion is asso­ciat­ed ­with a ­risk of per­ma­nent ­loss of the ­vision. Cavernous mal­for­ma­tions of ­optic chi­as­ma ­should be care­ful­ly eval­u­at­ed and con­sid­ered for pos­sible pre­ven­ta­tive sur­gi­cal resec­tion ­before it ­becomes symp­to­mat­ic.
