A 38-year-old man with a known history of hereditary multiple exostoses and no history of trauma presented with a painful right femur mass. While the clinical presentation was concerning for malignant degeneration or a large overlying bursitis, the radiologic evaluation demonstrated a large fractured pedunculated osteochondroma with a thick cartilage cap and underlying bone marrow edema. Traumatic fracture of an osteochondroma is an uncommon complication in patients with hereditary multiple exostoses. This case highlights an unusual presentation in which a patient with hereditary multiple exostoses and no history of trauma presented with a large fractured osteochondroma.
一名38岁男性，有遗传性多发性骨软骨瘤病史，无外伤史，因右侧股骨肿物伴疼痛就诊。虽然临床表现令人担忧恶性变或巨大的滑囊炎，但影像学评估显示为一个带蒂的大骨软骨瘤骨折，软骨帽增厚，并有骨髓水肿。骨软骨瘤的创伤性骨折在遗传性多发性骨软骨瘤患者中是一种不常见的并发症。本病例突出了一种不寻常的表现，即一名无外伤史的遗传性多发性骨软骨瘤患者出现了一个大的骨折性骨软骨瘤。
