Clinical Nuclear Medicine: November 2020 - Volume 45 - Issue 11 - p 900-901 doi: 10.1097/RLU.0000000000003256 Buy Metrics Abstract A 69-year-old man with a history of back pain, urinary obstruction, and deep vein thrombosis of both lower extremities 4 years earlier was diagnosed with rectal neuroendocrine tumor, grade 2, Ki-67 index 3%. 68Ga-DOTANOC PET/CT images showed a left pelvic mass extended to the lumen of the inferior vena cava with a high affinity for somatostatin receptor. A tubular focus of radiotracer accumulation after the course of inferior vena cava with filling defect was suggestive of tumor thrombus. Copyright © 2020 Wolters Kluwer Health, Inc.
