A 28 year old patient complained of sensory disturbances and pain in the right upper arm during pregnancy. During the 32nd week of her pregnancy, a large painful mass developed in the flexor muscles which, radiographically, showed some calcification. A diagnosis of a parosseous sarcoma was made; biopsy, however, indicated a diagnosis of non-traumatic myositis ossificans. Since the histological appearances of active myositis may be vary difficult to distinguish from a juxtacortical sarcoma, a right brachial angiogram and scintiscan were obtained. The angiographic and scintigraphic findings were erroneously considered to suggest malignancy. Following delivery, the tumour was removed. Futher histology confirmed the diagnosis of localised, non-traumatic myositis ossificans. The value of radiology, biopsy, angiography and scintigraphy are discussed with reference to our experience.
一名28岁的患者在怀孕期间抱怨右上臂感觉障碍和疼痛。在她怀孕第32周时，屈肌中出现了一个大的疼痛性肿块，影像学检查显示有一些钙化。诊断为骨旁肉瘤；然而，活检表明诊断为非创伤性骨化性肌炎。由于活动性骨化性肌炎的组织学表现可能很难与皮质旁肉瘤区分开来，因此进行了右肱血管造影和闪烁扫描。血管造影和闪烁扫描结果被错误地认为提示恶性肿瘤。分娩后，切除了肿瘤。进一步的组织学检查证实了局限性非创伤性骨化性肌炎的诊断。结合我们的经验讨论了放射学、活检、血管造影和闪烁扫描的价值。
