Intraarticular Lipoma of the Pisotriquetral Joint: A Rare Case Report

Abstract

AbstractIntraarticular lipomas are infrequently reported, with most reported cases occurring in the knee joint. A case of intraarticular lipoma in the small joints of the hand, specifically in the pisotriquetral joint, has been documented for the first time. A 24-year-old male visited the emergency department after a road traffic accident with a painful and swollen wrist. Radiographic examination revealed fractures of the distal radius and triquetrum. A subsequent wrist computed tomography scan identified an intraarticular lipoma within the pisotriquetral joint, further confirmed by ultrasonography. This article underscores the importance of recognizing that, though exceedingly rare, intraarticular lipomas should be considered in the differential diagnosis of soft-tissue tumors affecting the hand and wrist.
