目的：探讨掌指骨原发血管瘤的影像学特征，旨在提高对该病的认识和诊断正确率。方法回顾性分析经手术病理证实的9例掌指骨血管瘤患者的 X 线平片（9例）及 MRI（1例）表现。结果9例掌指骨血管瘤中髓型7例、骨膜型1例、皮质内型1例。髓型 X 线表现为典型的骨小梁稀疏、粗大，网格状或蜂窝状骨纹，略膨胀。骨膜型 X 线表现为皮质不规则增厚、边缘毛糙、见放射状骨膜新生骨，髓腔变窄。皮质内型 X 线表现为边界清晰的骨质破坏区，边缘轻度硬化；MRI 表现为 T1 WI 稍低信号，T2 WI 高信号，并夹杂少许 T1 WI 及 T2 WI 低信号，病灶突破骨皮质，形成软组织肿块，软组织肿块呈 T1 WI 稍低信号，T2 WI 高信号，信号欠均匀，临近软组织内可见迂曲血管影。结论掌指骨原发血管瘤的典型表现为骨小梁稀疏、粗大，网格状或蜂窝状骨纹，骨质略膨胀，MRI 有助于显示病灶范围、内部成分及引流血管。

Objective To investigate the imaging features of hemangioma in the metacarpals and phalanges .Methods The imaging mannifestations of 9 patients with hemangioma in the metacarpals and phalanges confirmed pathologically ,in‐cluding 9 cases for X‐ray and 1 case for MRI ,were retrospectively analysed in this work .Results Of those 9 patients with hemangioma ,7 were medullary type in phalanges ,1 was periosteum type ,and 1 was cortex type .In medullary type ,X‐ray showed a typical trabecular sparse ,coarse mesh or honeycomb bone pattern ,and slightly inflated .In periosteum type , X‐ray showed periosteal irregular cortical thickening ,rough edges ,radial periosteal new bone ,and the narrowed marrow . In cortex type ,X‐ray showed a clear boundary bone destruction ,slightly hardened edge .MRI showed slightly lower signal T1 WI ,T2 WI high signal ,and mixed with a little T1 WI and T2 WI low signal cortical lesion breakthrough ,forming a soft tissue mass ,soft tissue mass was slightly lower signal T1 WI ,T2 WI high signal ,the signal was less uniform and tortuous blood vessels were visible in the adjacent soft tissue shadow .Conclusion Primary hemangioma in phalanges typically ap‐pears as trabecular sparse ,coarse mesh or honeycomb pattern of bone ,bone slightly swell .MRI is telpful for showing le‐sions that contribute to the scope of internal components and draining blood vessels .
