The authors present a case of 18F-FDG-avid granulomatous reaction induced by fireworks injury of the chest wall in a patient with esophageal adenocarcinoma. This hypermetabolic lesion, involving the right pectoralis muscles, appeared slightly more prominent on restaging PET/CT imaging following chemotherapy and radiation therapy. Excisional biopsy of the lesion established the diagnosis of foreign-body granulomatous-type inflammation with surrounding foci of non-polarizable black foreign material and ruled out malignancy. The patient recalled accidentally shooting himself in the chest with a Roman candle at the age of 3.
作者报告了 1 例 18F-FDG 摄取的肉芽肿反应病例,该患者因胸壁烟花伤导致胸腺癌。在化疗和放疗后进行的再分期 PET/CT 成像中,该高代谢病变累及右侧胸大肌,表现为稍显突出。病变的切除活检确立了异物肉芽肿型炎症的诊断,伴有周围非极化黑色异物灶,排除了恶性肿瘤。患者回忆起在 3 岁时曾意外用罗马蜡烛枪射击胸部。
