Calcific myonecrosis is a rare disease that has been shown to be a late sequela of trauma. This article presents a 68-year-old man with calcific myonecrosis of the leg 40 years after a tibial fracture complicated with peroneal nerve palsy. The soft tissue mass increased in size after another injury to the leg that occurred two years before his presentation. Physical examination at presentation showed a palpable extra-osseous mass at the anterior aspect of the left leg; the mass was not adherent to adjacent soft-tissues and bone, and it was painless but tender to palpation. Radiographs of the left leg showed extensive calcification at the soft-tissue of the anterior and posterior leg. An ultrasonography-guided trocar biopsy was done; histological findings were indicative of calcific myonecrosis. Given the benign entity of the lesion and known high rate of complications, he was recommended for no further treatment except for clinical and imaging observation. Located at the site of the biopsy, he experienced infection with drainage that eventually healed after six months with antibiotics and wound dressing changes. During the last follow-up examination, two years after diagnosis, the patient was asymptomatic without progression of the mass.
钙化性肌炎是一种罕见疾病，已被证实是创伤的晚期后遗症。本文报告了一例 68 岁男性患者，在胫骨骨折合并腓总神经麻痹 40 年后出现腿部钙化性肌炎。在他就诊前两年，腿部再次受伤后，软组织肿块增大。就诊时体格检查显示左小腿前侧可触及到一个可触及的骨外肿块；肿块与邻近的软组织和骨骼无粘连，无触痛，但压痛。左小腿的 X 线片显示小腿前后软组织广泛钙化。进行了超声引导下的穿刺活检；组织学检查结果提示为钙化性肌炎。鉴于病变的良性性质和已知的高并发症发生率，除了临床和影像学观察外，不建议进一步治疗。在活检部位，他经历了感染并引流，最终在六个月的抗生素和伤口换药治疗后愈合。在诊断后两年的最后一次随访检查中，患者无症状，肿块无进展。
