Abstract

There are various congenital anomalies and anatomical variations of the spleen (CAAVS). CAAVS are common and are often associated with systemic anomalies. Widespread use of computed tomography and magnetic resonance imaging in a variety of clinical situations has increased the detection of CAAVS. However, CAAVS are frequently overlooked and are occasionally misdiagnosed as pathologic disease entities. This article aimed to review the various manifestations of CAAVS with radiologic findings.
