The Achilles tendon is the strongest and largest tendon in the human body, composed of the distal confluence of the gastrocnemius and soleus muscles and may also include the plantaris longus tendons. Despite its tremendous strength, it is frequently injured. Soft tissue tumors or tumor-like conditions of Achilles tendon are much less common in comparison to traumatic and infectious/inflammatory lesions. These include giant cell tumor of the tendon sheath, pigmented villonodular synovitis, xanthomas, hematomas, and tophaceous gout. We present a case of a myxochondroid mass arising from the Achilles tendon in a 17-year-old female softball player detected after a minor trauma. According to our knowledge, this is the first case reported in the literature detailing the radiological findings and histopathological diagnosis of a myxochondroid mass arising from a tendon.
跟腱是人体最强壮、最大的肌腱，由腓肠肌和比目鱼肌的远端汇合而成，也可能包括跖肌腱。尽管它力量巨大，但却经常受伤。与创伤性和感染性/炎症性病变相比，跟腱的软组织肿瘤或肿瘤样病变要少见得多。这些病变包括腱鞘巨细胞瘤、色素沉着绒毛结节性滑膜炎、黄色瘤、血肿和痛风石性痛风。我们报告了一例17岁女性垒球运动员在轻微创伤后发现的跟腱黏液软骨样肿块病例。据我们所知，这是文献中首次报道的详细描述肌腱黏液软骨样肿块的放射学表现和组织病理学诊断的病例。
