Case in brief

A 57-year-old man with abdominal pain and diarrhea had a spiculated, calcified mesenteric mass on contrast-enhanced CT, initially considered a desmoid tumor. The mass was ametabolic on ¹⁸F-FDG PET/CT, supporting that impression. In contrast, ⁶⁸Ga DOTATATE PET/CT showed intense uptake in the mass and an ileal focus. Histopathology established an ileal neuroendocrine tumor with mesenteric lymph node metastasis.

What made this case unusual

The mesenteric mass had a “sunburst” calcification pattern and was FDG-negative, yet showed intense ⁶⁸Ga DOTATATE uptake alongside the primary ileal focus.

Diagnostic / clinical pearl

Ametabolic ¹⁸F-FDG PET/CT does not exclude an ileal neuroendocrine tumor in a patient with a spiculated mesenteric mass; ⁶⁸Ga DOTATATE PET/CT can help identify the primary focus and assess disease extent.
