Arachnoid cyst with spontaneous intracystic hemorrhage and chronic subdural hematoma

Abstract

We report a case of arachnoid cyst in which subdural hematoma and intracystic hemorrhage developed spontaneously. Usually, arachnoid cysts are asymptomatic, but can become symptomatic because of cyst enlargement or hemorrhage, often after mild head trauma. Although they are sometimes combined with subdural hematoma, intracystic hemorrhage has rarely been observed. Our patient had a simultaneous subdural hematoma and intracystic hemorrhage without evidence of head trauma.

Keywords: Arachnoid cyst; Spontaneous intracystic hemorrhage; Subdural hematoma.
