Published: March 2023

This case report follows a 70-year-old male patient with Zollinger-Ellison syndrome undergoing computed tomography (CT) for weight loss and surveillance of bilateral adrenal nodules. Incidentally, diffuse gastric and duodenal wall thickening was noted on CT. The patient underwent esophagogastroduodenoscopy with biopsy results showing well-differentiated neuroendocrine tumors (NET) in the stomach and duodenum. Subsequent imaging with gallium-68 DOTATATE PET/CT showed intense tracer uptake in the stomach and proximal duodenum with liver and regional nodal metastases around the superior mesenteric artery. This case outlines the utility of Ga-68 DOTATATE PET/CT in diagnosing, localizing, and staging NET such as gastrinomas.

Background: Meningiomas are the most common primary intracranial tumor. Somatostatin receptor 2 (SSTR 2) is almost universally expressed in meningioma tissue. For patients who require adjuvant radiation, SSTR based (68)Ga-DOTATATE positron emission tomography (PET) imaging can detect additional or residual disease not discernible on magnetic resonance imaging (MRI).

Insulinoma is a relatively uncommon pancreatic neuroendocrine tumor, with approximately 10% of the cases being malignant. Diabetes mellitus (DM) with concurrent insulinoma is very rare and the diagnosis of such condition is easily missed as it can be misconstrued as improved glycemic control. Therefore, persistent hypoglycemic symptoms even after stopping antidiabetic medications may be considered for insulinoma.

We present a rare case of physiological uptake of [ Lu]Lu-DOTATATE in the gallbladder, observed post-therapy, in a 47-year-old man with grade I duodenal neuroendocrine tumor (NET), despite no uptake being observed pre-therapy in the somatostatin receptor-positron emission tomography. On planar scintigraphy, the gallbladder uptake could have been misidentified as liver metastasis. By utilizing single photon emission computed tomography/computed tomography imaging, we were able to precisely localize the tracer and obtain anatomical morphological characteristics, thereby averting the potential for misinterpretation of liver metastasis resulting from the gallbladder's physiological uptake of [ Lu]Lu-DOTATATE in NET patients.

Patients of head and neck squamous cell carcinoma (HNSCC) experience increased risk of developing second primary cancer (SPC) necessitating active surveillance during their disease course. SPCs are associated with poor prognosis and are the leading cause of long-term morbidity and mortality impacting survival of patients with HNSCC. Small cell neuroendocrine carcinoma (SmNEC) is a rare but aggressive neoplasm with poor prognosis and high risk of local recurrence and distant metastasis.

Purpose: The aim of this study was to compare the clinical application value of 68Ga-DOTATATE and 18F-FDG PET/CT in Epstein-Barr virus (EBV)-positive nonkeratinizing nasopharyngeal carcinoma.

Patients And Methods: Patients underwent 18F-FDG and 68Ga-DOTATATE PET scans. The lesion numbers, tracer parameters, and primary tumor volume derived from contrast-enhanced MRI, 18F-FDG, and 68Ga-DOTATATE PET were compared.
