A 25-year-old man presented with a firm tissue mass of the right elbow and intermittent pain. CT showed a dumbbell-shaped soft tissue mass with foci of dense calcification in the muscular layer of the triceps brachii muscle and subcutaneous tissue. The tumor showed slightly higher signal intensity on T1-weighted images and markedly higher intensity on T2-weighted images compared with the surrounding muscle. Prominent enhancement was present after the intravenous injection of Gd-DTPA. Histopathological examination of the resected specimen revealed a deep soft tissue leiomyoma.
一名25岁男性患者，右肘部出现质地坚硬的组织肿块，并伴有间歇性疼痛。CT显示一个哑铃形软组织肿块，肱三头肌肌肉层和皮下组织内有致密钙化灶。与周围肌肉相比，该肿瘤在T1加权图像上信号强度略高，在T2加权图像上信号强度明显更高。静脉注射钆喷酸葡胺后有明显强化。切除标本的组织病理学检查显示为深部软组织平滑肌瘤。
