Winging of scapula is defined as a failure of dynamic stabilizing structures that anchor the scapula to the chest wall, leading to prominence of the medial border of scapula. It could be primary, secondary, or voluntary. Primary winging could be true winging due to neuromuscular causes or pseudo-winging due to osseous or soft-tissue masses. A scapular osteochondroma is a very rare presentation site and causes pseudo-winging leading to pushing away of the scapula away from the chest wall presenting as medial border prominence. Here, we are reporting a rare case of a scapular osteochondroma causing a pseudo-winging of the scapula.
A 2-year-old male child presented with painless, immobile, and non-fluctuant swelling over the left scapular region, insidious in onset and progressive in nature. On examination, a non-tender, immobile swelling was palpable with a painless and unrestricted range of motion at the shoulder joint. After evaluating radiographs and CT scan, the patient was diagnosed to have a ventral scapular osteochondroma leading to pseudo-winging of the scapula.
Despite the rarity, a differential diagnosis of a scapular osteochondroma should be kept in mind while examining a young child presenting with a winged scapula.
肩胛翼状畸形定义为将肩胛骨固定于胸壁的动态稳定结构功能障碍，导致肩胛骨内侧缘突出。它可以是原发性、继发性或假性的。原发性翼状畸形可能是由于神经肌肉原因导致的真性翼状畸形，或由于骨或软组织肿块导致的假性翼状畸形。肩胛骨软骨瘤是一种非常罕见的发病部位，可导致假性翼状畸形，使肩胛骨从胸壁推开，表现为内侧缘突出。在此，我们报告一例罕见的肩胛骨软骨瘤导致肩胛骨假性翼状畸形的病例。
一名2岁男童，左肩胛区出现无痛、固定且无波动感的肿胀，起病隐匿且呈进行性发展。检查时，可触及一个无压痛、固定的肿胀，肩关节活动范围无痛且不受限。经X线片和CT扫描评估后，该患者被诊断为腹侧肩胛骨软骨瘤导致肩胛骨假性翼状畸形。
尽管罕见，但在检查出现肩胛翼状畸形的幼儿时，应考虑肩胛骨软骨瘤的鉴别诊断。
