Preface: Arachnoid cyst is a commonly discerned, benign, fluid-filled lesion of the central nervous system. The congenital, miniature or enlarged arachnoid cyst enunciates a subarachnoid accumulation of cerebrospinal fluid. Arachnoid cyst incriminates cranial and spinal meninges and may expand within the brain or spinal cord. Arachnoid cyst emerges as a congenital lesion on account of reduplication or disruption of leptomeninges. Besides, the cyst may occur as a sporadic lesion or appears associated with diverse malformations or disorders. Arachnoid cyst is delineated as an incidental discovery upon imaging of central nervous system. Exceptionally, an arachnoid cyst may rupture to configure a subdural hygroma or a subdural haematoma or haemorrhage within the cyst may occur. Cyst rupture may be spontaneous or traumatic in origin.
