Abstract

A rare case of multicentric telangiectatic osteosarcoma in a 29-year-old woman is described. A plain X-ray showed a pure osteolytic lesion of the navicular, cuboid and I, II, III cuneiform bones. On magnetic resonance images, a T1-weighted image showed heterogeneous low signal intensity. A T2-weighted image showed heterogeneous high signal change with multicentric cystic foci and fluid-fluid levels. Histologically, the lesion showed typical telangiectatic osteosarcoma with numerous atypical giant cells.

摘要

本文描述了一例29岁女性多中心性毛细血管扩张性骨肉瘤的罕见病例。X线平片显示舟骨、骰骨及第Ⅰ、Ⅱ、Ⅲ楔骨有单纯溶骨性病变。磁共振成像（MRI）上，T1加权像显示不均匀低信号强度。T2加权像显示不均匀高信号改变，伴有多中心囊性病灶及液-液平面。组织学上，病变表现为典型的毛细血管扩张性骨肉瘤，伴有大量非典型巨细胞。
