摘要

A IS-year-old boy with myositis ossificans in the lateral aspect of middle portion of left thigh was studied by triple-phase Tc-99m MDP bone scintigraphy and computed tomography of both thighs. The myositis ossificans is a circumscribed lesion adjacent to left femur. The triplephase bone scintigraphy is sensitive to study hypervasularity in soft tissue component of the lesion and define the lesion is confined to soft tissue and contiguous to adjacent femur. The computed tomography can accurately demonstrate the nature and involvement of the lesion with calcified spots scattered among muscles in the paraosseous of lateral aspect of left femur and periosteal reaction of adjacent femur. A combined use of a triple-phase bone scintigrapjy and computed tomography is useful in the evaluation and detection of a myositis osslficans.

骨化性肌炎是一種常見的局部軟組織，有非自養性的骨骼或軟骨發生的疾病。該病病因目前尚不明瞭，一般認為與外傷有關。一名十五歲少年，在左腿中部外側有一處痛性的軟體組織腫瘤，經臨床的診斷為疑限性骨化性肌炎，病理的檢查證明係骨化性肌炎。本文報告應用三相骨骼閃爍描繪暨腿部電腦斷層圖掃描診斷骨化性肌炎的評價。
