Mesenteric Mesonephric Adenocarcinoma on 68Ga-FAPI PET/CT

Abstract

Mesenteric mesonephric adenocarcinoma is an uncommon mesenteric neoplasm, which was arising from the mesonephric remnant of the female reproductive tract. Herein, we report the 68Ga-FAPI PET/CT findings in a 66-year-old woman with mesenteric mesonephric adenocarcinoma.

18F-FAPI-04 PET/CT in a Case of Primary Gastric Plasmacytoma

“…FAPI PET/CT may be not superior to FDG PET/CT in detecting osseous or extraosseous myeloma lesions 13 . This case indicates gastric plasmacytoma should be included in the differential diagnosis of malignant and benign etiologies of stomach-related elevated FAPI activity including adenocarcinoma, 17 gastrointestinal stromal tumor, 18 Kaposi sarcoma, 19 lymphoma, 20 chronic gastritis, 21 and fibrous hyperplasia 22 …”

Cutaneous Metastasis of Ovarian Cancer on 68Ga-FAPI PET/CT

“…[1][2][3] In this case, the skin and lymph node lesions demonstrated intense FAPI uptake with a very preferable tumor-to-background ratio. Previous studies have shown that cutaneous neurofibromatosis, 4 melanoma, 5 and plasmacytosis 6 also present with intense FAPI uptake. Therefore, cutaneous metastasis of ovarian cancer should be considered in the differential diagnosis of cutaneous lesions with high FAPI uptake.…”

Elevated 68Ga-FAPI Activity in Leiomyosarcoma

“…Studies have shown that 68 Ga-FAPI PET/CT may be a more accurate choice than 18 F-FDG PET/CT in detecting primary and metastatic lesions 1–3 . Many abdominal tumors and nonneoplastic lesions present with increased FAPI uptake, including adenocarcinoma, 4 lymphoma, 5 sarcoma, 6–8 and tuberculosis 9 . Nuclear medicine physician should consider the patient’s various conditions comprehensively and make the differential diagnosis.…”
