두개내 발생한 지주막낭종 치험 2예 = Two Cases of Intracranial Arachnoid Cyst

다국어 초록 (Multilingual Abstract)

The intracranial arachnoid cysts are benign lesions in nature which thin walled cysts lying in relation to or enclosed by the subarachnoid space, filled with clear fluid.
They may be due to developmental defects of the brain or meninges and secondary to inflammation, vascular occlusion or trauma but etiology of a large percentage is not well understood.
In general, locations are near primary fissure and cisterns of the cerebral cortex and cerebellum. The clinical features and courses are unusual. Preoperative diagnosis is unlikely to be made but treatment is followed by good result. We had experienced two cases of intracranial arachnoid cysts which occures in middle cranial fossa, and cerebral hemisphere. Pathologic diagnosis are arachnoid cysts.
