Abstract

Abstract Introduction: Myositis ossificans (MO) is a rare disorder of ectopic ossification in soft tissue or muscle, usually associated with trauma or hereditary conditions. Surgical excision is the mainstay of treatment with anti-inflammatory medications. Radiotherapy is used as an adjuvant therapy, to treat residual lesions and to relieve symptoms. Methods: A 36-year-old male presented with a localised tender swelling in left popliteal fossa and progressive pain in lower limb for 6 weeks and restricted mobility for 3 weeks. A local excision of calcified mass arising from fascia of left popliteal fossa was consistent with MO features. Due to persistent symptoms and a residual lesion on imaging, adjuvant external beam radiation therapy (EBRT) was planned with a low dose of 10 Gy (Gray) in 2 fractions on 2 consecutive days in a prone position after 2 weeks using 6 MV (mega voltage) photon beam on linear accelerator (LINAC). Results: Radiotherapy resulted in a significant clinical improvement without any related acute toxicities. Patient is disease-free and on regular follow-up without any progression after 2 years. Conclusion: Post-operative EBRT can stabilise residual MO and treat intractable pain when lesion lies in the vicinity of a neurovascular bundle

放射治疗非外伤性腘窝区骨化性肌炎1例

摘要简介:骨化性肌炎(MO)是一种罕见的软组织或肌肉异位骨化疾病，通常与创伤或遗传条件有关。手术切除是抗炎药物治疗的主要方法。放射治疗是一种辅助治疗，用于治疗残留病变和缓解症状。方法:36岁男性，左腘窝局部压痛性肿胀，进行性下肢疼痛6周，活动受限3周。局部切除源自左腘窝筋膜的钙化肿块符合MO特征。由于持续的症状和影像学上残留的病变，辅助外束放射治疗(EBRT)计划在2周后使用6 MV(兆电压)光子束在线性加速器(LINAC)上，连续2天在俯卧位上进行低剂量的10 Gy (Gray)。结果:放疗后临床改善明显，无相关急性毒性反应。患者无疾病，定期随访2年后无任何进展。结论:病灶位于神经血管束附近时，术后EBRT能稳定残余MO，治疗顽固性疼痛
