一名 71 岁女性患者，已知印戒细胞癌病史，出现弥漫性骨痛和贫血症状。一项 18F-氟脱氧葡萄糖 (FDG) 正电子发射断层扫描/计算机断层扫描研究显示，中轴和近端阑尾骨骼中存在弥漫性异质代谢亢进性硬化病变。没有检测到其他 18F-FDG 亲和性病变。随后的骨髓活检证实了源自胃原发部位的转移癌的诊断。开始姑息治疗；然而，患者病情恶化，两个月后去世。版权所有© 2024 The Author。由 Galenos 出版社代表土耳其核医学学会出版。

A 71-year-old female patient with a known history of signet-ring cell carcinoma presented with diffuse bone pain and anemic symptoms. An 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography study revealed diffuse heterogeneous hypermetabolic sclerotic lesions in the axial and proximal appendicular skeleton. No other 18F-FDG-avid lesions were detected. Subsequent bone marrow biopsy confirmed the diagnosis of metastatic carcinoma originating from the gastric primary site. Palliative treatment was initiated; however, the patient's condition deteriorated, and she succumbed to the disease two months later.Copyright© 2024 The Author.
