title: [Intrachiasmal hematoma].
abstract: This case report describes 41-year-old female who suffered from progressive visual loss due to chiasmal apoplexy. Her neurological examination revealed bitemporal hemianopia without any pathological changes of optic disks. MRI showed round-shape, hyperintensive on T1WI and T2WI lesion inside the chiasm without enhancement after IV contrast administration. The lesion was suspicious of acute or subacute hemorrhage. MRI and CT scans revealed characteristic signs that supported the diagnosis of intrachiasmal hemorrhage. Surgery was performed via a pterional approach. Minimally invasive surgical intervention to chiasm allowed us to minimize the risk of further visual deterioration in postoperative period. Meta-analysis of publications highlights the various aspects of diagnosis and management of intrachiasmal hemorrhages.
