A 20-year-old man with gastrointestinal symptoms and weight loss underwent FDG PET/CT, which revealed multiple hypermetabolic hepatic lesions concerning for metastatic liver disease. The outcome of liver biopsy was consistent with the diagnosis of peliosis hepatis which is a rare benign disease characterized by multiple blood-filled cystic spaces in the hepatic parenchyma. The findings of peliosis on FDG PET/CT are not well reported in the literature. These interesting images emphasize the importance of including peliosis hepatis in the differential diagnosis of multiple hypermetabolic hepatic lesions on FDG PET/CT, which could simulate malignancy.
一位 20 岁男性，因胃肠道症状和体重减轻接受了 FDG PET/CT 检查，结果显示多个高代谢性肝病变，考虑为肝转移瘤。肝活检的结果与肝血窦扩张症的诊断一致，肝血窦扩张症是一种罕见的良性疾病，其特征是肝实质内有多个充满血液的囊性空间。FDG PET/CT 上的肝血窦扩张症表现尚未在文献中得到很好的报道。这些有趣的图像强调了在 FDG PET/CT 上多个高代谢性肝病变的鉴别诊断中包括肝血窦扩张症的重要性，因为它可能模拟恶性肿瘤。
