Whole-body Ga-67 scintigraphy showed intense gastrointestinal uptake. Fluorodeoxyglucose position emission tomography (FDG PET) revealed hypermetabolism in the left lower neck, mediastinum, stomach, and extensively in a bowel loop. The histologic findings of a gastric biopsy through endoscopy disclosed the typical "starry sky" appearance of Burkitt's lymphoma. Based on these findings, the patient was diagnosed as having a posttransplant lymphoproliferative disorder. Chemotherapy was then arranged for subsequent treatment.[SDGs]SDG3fluorodeoxyglucose f 18; gallium citrate ga 67; abdominal pain; adult; anorexia; article; Burkitt lymphoma; case report; congestive cardiomyopathy; Epstein Barr virus; heart transplantation; histopathology; human; lymphoproliferative disease; male; positron emission tomography; stomach biopsy; whole body scintiscanning; Adult; Burkitt Lymphoma; Fluorodeoxyglucose F18; Gallium Radioisotopes; Heart Transplantation; Humans; Lymphoproliferative Disorders; Male; Postoperative Complications; Tomography, Emission-Computedjournal article10.1097/01.rlu.0000123325.90461.13150693392-s2.0-1942453766
