UNMASKING THE UNUSUAL:EIP ANOMALIES MASQUERADING AS GANGLION

Abstract

These muscle anomalies are of rare occurrence; however, when present, they can mimic other conditions like ganglia, particularly Anomalous extensor muscles of the hand, specifically Extensor Indicis Proprius (EIP)(1). We describe a rare anomalous epiphanic (EIP) muscle that clinically presented as a ganglion cyst in a 40 year old male who presented with a painless dorsal wrist swelling for 6 months. The muscle was truncated through excision of its middle third, with resolution of symptoms. Understanding the presence of such anatomical variation is crucial for the diagnose and management of handpathologies.
