It can be confused with pancreas pathologies as it shows an extramural growth pattern. The case is here presented of a 65-year-old male who presented with the complaints of abdominal pain, nausea and vomiting. On contrast abdominal tomography, a centrally hypodense, necrotic mass, 140×115×100 mm in size, was observed in the pancreas head. With a preliminary diagnosis of neuroendocrine tumour/serous cystic neoplasia, a Whipple + partial vena cava resection + primary repair operation was performed. The pathology was reported as duodenal GIST. The patient was discharged with medication and referred to the oncology clinic.
