    Abstract:
    Hemorrhage into the structures of the anterior visual pathway, apoplexy of the chiasma or optic nerves, is a rare pathology that can be caused by different pathological processes among which cavernous angioma and arteriovenous malformation are more frequently mentioned. The cause of chiasmatic apoplexy may be also hemorrhage into the tumor--chiasmatic glioma of blood penetration into the chiasma in pituitary apoplexy. The authors describe a rare case of chiasmatic apoplexy whose cause was chiasmatic cavernoma. In addition to acute visual disorders suggesting the involvement of the left optic nerve, chiasma, and left visual pathway, 23-year-old patient had endocrine disorders as polyuria, polydipsia, which first suggests craniopharyngioma and glioma of the chiasma. A capsule and hematomic clots were removed from the thickened left optic nerve and left chiasmatic half during surgery. Only did a morphological study involving immunohistochemical analysis permit identification of the process as hemorrhage from cavernous micromalformation with the formation of hematoma.
