Diffuse-type giant cell tumor of the tendon sheath (GCTTS) is a rare, benign, yet locally aggressive soft tissue tumor commonly affecting the hand. This case report presents a 55-year-old male with a 5-year history of GCTTS in the flexor tendon sheath of the long finger. MRI played a critical role in both diagnosis and surgical planning, revealing key features such as the tumor's 10 cm length, hemosiderin deposition, and blooming artifacts. The patient underwent successful surgical excision with no recurrence at the 1-year follow-up. This case underscores the significance of MRI in preventing functional impairment and reducing recurrence risk in diffuse-type GCTTS.
腱鞘弥漫型巨细胞瘤（GCTTS）是一种罕见的良性但具有局部侵袭性的软组织肿瘤，常见于手部。本病例报告介绍了一名55岁男性，其在长指屈肌腱鞘患有GCTTS已有5年病史。MRI在诊断和手术规划中都发挥了关键作用，揭示了肿瘤长度10厘米、含铁血黄素沉积和磁敏感伪影等关键特征。患者接受了成功的手术切除，在1年随访中无复发。该病例强调了MRI在预防弥漫型GCTTS功能障碍和降低复发风险方面的重要性。
