Abstract

Arachnoid cysts (AC) are benign, non-neoplastic fluid-filled malformations of the arachnoid tissue.
Approximately 50-65% occur in the middle cranial fossa and predominantly on the left side, followed by
retrocerebellar and convexity locations. Tremendous development and usage of cross-sectional imaging
modalities suggest a higher prevalence of AC than previously thought. Since large arachnoid cysts express
mass effect on surrounding neurovascular structures, a surgical approach is preferred to passive
observation. Nevertheless, the symptomatology is frequently subjective and difficult to validate, and the
causal link between symptoms and an arachnoid cyst is often dubious. Therefore, the operative indication
and the best surgical modality for patients with AC remain controversial. Surgical options include opencraniotomy or endoscopic cyst fenestration, cystoperitoneal, cystosubdural, ventriculoperitoneal shunt
insertion, or marsupialization via a craniotomy. The complications of these procedures include subdural
hematomas, hygromas, hydrocephalus, cerebral edema, postoperative secondary arachnoid cyst, and, more
rarely, remote intraparenchymal or subarachnoidal hemorrhage.
