Neuroendocrine Tumor Diagnosis and Management: Ga-DOTATATE PET/CT.

Objective: The purpose of this article is to provide a review of the use of Ga tetraazacyclododecanetetraacetic acid-DPhe1-Tyr3-octreotate (DOTATATE) PET/CT, a functional imaging modality for assessment of well-differentiated neuroendocrine tumors (NETs). It has become the preferred imaging modality for initial diagnosis, selection of patients for peptide receptor radionuclide therapy, and localization of unknown primary tumors. The National Comprehensive Cancer Network guideline has added Ga-DOTATATE PET/CT as an appropriate test in the management of NETs.

Testicular Metastasis from Recurrent Gastroesophageal Junction Adenocarcinoma: Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography Findings.

Testicular metastasis from gastroesophageal junction (GEJ) adenocarcinoma is a very rare condition. A 57-year-old male with a history of neoadjuvant chemotherapy and surgery for HER-2-positive GEJ adenocarcinoma underwent a follow-up F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT). It revealed multiple metastases including bilateral testicular and L4 laminar metastasis.

Bone Scan in Evaluation of Bone Viability in Severe Frostbite of the Hand.

A 39-year-old male presented to the emergency department (ED) with frostbite to the fingers of both hands. In the ED, he received warm baths, acetylsalicylic acid, clopidogrel, and heparin. A three-phase bone scintigraphy with technetium-99m-methylene diphosphonate revealed absent radiotracer uptake in distal phalanges of both hands.

PET/CT in an 8-Year-Old Girl With Epstein-Barr Virus-Associated Smooth Muscle Tumor.

Epstein-Barr virus-associated smooth muscle tumor is a rare indolent neoplasm, which can occur in unusual locations. It has been reported in immunosuppressed individuals in only 3 settings: posttransplant, human immunodeficiency virus infection, and primary immunodeficiency. Here, we present CT, MRI, and F-FDG PET/CT findings of Epstein-Barr virus-associated smooth muscle tumor in an 8-year-old girl with primary immunodeficiency and metachronous adrenal involvement.
