title: Optic chiasmal cavernous angioma: A rare suprasellar vascular malformation.
abstract: BACKGROUND
  Suprasellar cavernous malformation in the optic pathway is not commonly encountered. To date, there are only few reports present in the literature.
  
  
  METHODS
  The authors report a rare case of suprasellar optic pathway cavernous malformation in a 33-year-old female who presented with progressive visual loss. Her imaging revealed a large heterogeneous, hyperintense, hemorrhagic right suprasellar extra-axial complex cystic structure, causing mass effect on the adjacent hypothalamus and third ventricle displacing these structures. Gross total resection of the lesion was achieved utilizing a right frontal craniotomy approach. Histopathological examination confirmed the diagnosis of suprasellar chiasmal cavernous malformation.
  
  
  CONCLUSIONS
  Although visual pathway cavernous malformation is a rare event, it should be included in the differential diagnosis of lesions occurring suprasellarly in the visual pathway and hypothalamus.
