Intra-articular lipomas are infrequently reported, with most reported cases occurring in the knee joint. A case of intra-articular 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 intra-articular lipoma within the pisotriquetral joint, further confirmed by ultrasonography. This article underscores the importance of recognizing that, though exceedingly rare, intra-articular lipomas should be considered in the differential diagnosis of soft-tissue tumors affecting the hand and wrist.
关节内脂肪瘤鲜有报道，大多数报道的病例发生在膝关节。首次记录了一例手部小关节，特别是豌豆三角骨间关节的关节内脂肪瘤病例。一名24岁男性在道路交通事故后因手腕疼痛肿胀前往急诊科就诊。影像学检查显示桡骨远端和三角骨骨折。随后的腕部计算机断层扫描在豌豆三角骨间关节内发现了一个关节内脂肪瘤，超声检查进一步证实了这一发现。本文强调了认识到以下这点的重要性：尽管极为罕见，但在手部和腕部软组织肿瘤的鉴别诊断中应考虑关节内脂肪瘤。
