摘要
目的:探讨手足短骨转移瘤的影像学表现。方法:回顾性分析16例手足短骨转移瘤患者的临床及影像学资料。结果:16例中病灶位于手部6例(指骨4例,掌骨1例,腕舟骨1例),位于足部10例(跟骨3例,跖骨5例,趾骨2例),其中11例为手部或足部单发,5例多发。13例能明确原发肿瘤,分别为肺癌7例,乳腺癌2例,肾癌、宫颈癌、甲状腺癌、结直肠癌各1例,3例原发肿瘤不明。影像学主要表现为溶骨性骨质破坏,9例在病灶部位可见软组织肿块,2例出现轻微骨膜反应,2例合并病理性骨折。结论:手足短骨转移瘤罕见,容易误诊、漏诊,尤其是单发病灶或原发肿瘤不明的患者,结合患者病史和多种影像学表现有助于早期明确诊断。
Objective:To investigate the clinical symptoms and imaging manifestations of limb os breve metastases. Methods:Imaging data of 16 cases who were diagnosed as limb os breve metastases were analyzed retrospectively. Results:In all 16 cases,6 cases were in bones of hands and 10 cases in bones of feet,among which 11 cases were single in hands or feet, 5 cases were multiple and accompanied by involvement of other bones. In the 16 cases,phalanges were involved in 4 cases, metacarpals in 1 case, scaphoid bone in 1 case, calcaneus in 3 cases, metatarsal bones in 5 cases, and phalanges of toe in 2 cases. The primary tumors were determinable in 13 cases:7 lung cancers, 2 breast cancers, 1 renal cancer, 1 cancer of cervix, 1 cancer,and 1 colorectal cancer; whereas there were 3 cases with indeterminable primary tumors. The main imaging manifestations were lyric bone destructions:9 cases with soft-tissue mass adjacent to the lesions, 2 cases with mild periosteal reaction,and 2 cases with pathological fractures. Conclusion:Since metastatic tumors of short bones of limbs are rare,diagnosis is likely to be missed or delayed, especially in those cases whose lesions are single or the primary tumors are indeterminable. A combination of medical history and various imaging data will be helpful to early diagnosis.
