Arachnoid Cysts – Common and Uncommon Clinical Presentations and Radiological Features

Logan C, Asadi H, Kok HK, Looby S, O’Hare A, Thornton J and Brennan P

Abstract

Arachnoid cysts are benign, extra axial, cystic lesions, formed due to congenital splitting of the arachnoid layer. They are often discovered incidentally, either by fetal cranial ultrasound or as an asymptomatic finding on subsequent neuroimaging studies in adulthood. In this article, we present a pictorial review demonstrating the typical imaging features for arachnoid cysts and also include imaging appearances of more atypical arachnoid cysts and their potential complications. We also discuss the epidemiology, pathogenesis, imaging features, differential diagnosis and clinical presentation of arachnoid cysts according to their location and present a brief outline of treatment options.
