A case of leiomyoma with prominent calcification in the deep soft tissue of the shoulder is reported. The tumor showed mulberry-like calcifications on radiographs and computed tomography scans. Magnetic resonance imaging (MRI) showed well-circumscribed solid tumor with multiple signal voids. Although the signal intensity characteristics of the tumor matrix on plain MRI resembled those of chondroid matrix, the entire tumor was enhanced by gadopentetate dimeglumine and could be differentiated from chondrogenic tumors. MRI was also useful in evaluating the tumor extent.
报告一例肩部深部软组织平滑肌瘤伴显著钙化。该肿瘤在X线片和计算机断层扫描上显示出桑葚样钙化。磁共振成像（MRI）显示边界清晰的实性肿瘤，有多个信号缺失区。虽然平扫MRI上肿瘤基质的信号强度特征类似于软骨样基质，但整个肿瘤在注射钆喷酸葡胺后强化，可与软骨源性肿瘤相鉴别。MRI在评估肿瘤范围方面也很有用。
