Abstract
This case report follows a 63-year-old female patient with a history of a gastroenteropancreatic (GEP) neuroendocrine tumor of the terminal ileum who developed ovarian metastasis and later progressed to peritoneal carcinomatosis. The patient was found to have worsening metastasis on CT that was subsequently confirmed with ((68)Ga)-DOTATATE PET/CT imaging. This case outlines the rare metastatic nature of a primary ileal neuroendocrine tumor and emphasizes the efficacy of ((68)Ga)-DOTATATE PET/CT imaging in the localization, progression, and treatment of neuroendocrine metastatic disease.
