A 50-year-old woman was found with a hypervascular abdominal mass in the right lower quadrant in contrast-enhanced CT. Somatostatin receptor scintigraphy with Tc-HYNIC-TOC showed positivity of the abdominal mass and detected additional lesion with moderate increased radioactivity in the right axilla. In F-FDG PET/CT, both of the lesions were FDG-avid. A hypermetabolic node in the right supraclavicular fossa was also noted. The histopathological examination of the abdominal mass after surgical resection revealed Castleman disease, a mixed hyaline vascular and plasma cell variant. The right axillary and supraclavicular lesions were considered involvement of Castleman disease.
一位 50 岁女性在增强 CT 中发现右下腹部有一个富血管性腹部肿块。Tc-HYNIC-TOC 生长抑素受体闪烁显像显示腹部肿块呈阳性，并在右侧腋窝发现了另一个放射性中度增加的病灶。在 F-FDG PET/CT 中，两个病灶均摄取 FDG。还注意到右锁骨上窝有一个高代谢性结节。腹部肿块切除术后的组织病理学检查显示为Castleman 病，为混合性透明血管和浆细胞型。右侧腋窝和锁骨上病变被认为是 Castleman 病的累及。
