Abstract

We report the case of a 7-year-old boy with a calcified leiomyoma in the right gluteal muscle. Radiography and CT showed a well-defined soft tissue mass with mulberry-like calcifications that superficially resembled chondroid matrix calcification. The mass exhibited high-signal intensity intermingled with spotty low-signal intensity on T2-weighted MRI which was attributable to extensive non-malignant degeneration of the tumour.

摘要

我们报告了一例7岁男孩，其右侧臀肌有一个钙化平滑肌瘤。X线摄影和CT显示一个边界清晰的软组织肿块，伴有桑葚样钙化，表面类似软骨样基质钙化。在T2加权磁共振成像（MRI）上，该肿块表现为高信号强度夹杂着散在的低信号强度，这归因于肿瘤广泛的非恶性退变。
