Abstract
A 59-year-old woman presented to the Department of Gastroenterology complaining of progressing weight loss, unexplained diarrhoea,
and, as revealed by abdominal ultrasound, numerous hyperechogenic foci in the liver. The immunohistochemical evaluations of the
specimens from biopsy revealed well-differentiated hepatic neuroendocrine metastases. The biochemical marker levels, including serum
chromogranin A (CGA) and urine 5-hydroxyindolacetic acid (5-HIAA) 24-hour excretion, were significantly elevated. Whole body somatostatin
receptor scintigraphy showed tracer accumulation in the liver lesions, with no extrahepatic tumour, possibly the primary origin.
Long-term somatostatin analog therapy was initiated and a peptide-receptor targeted radionuclide therapy decision was made parallel to
this treatment. Therefore, a followed-up CT scan of the abdomen showed, as well as the metastatic changes within the liver, a wellvascularised
jejunal tumour suspected to be the primary focus of the disseminated neuroendocrine neoplasm. Unexpectedly, the pathological
examination revealed a positive cell reaction for CD 117, confirming the diagnosis of a rare jejunal stromal tumour. Two months later
peptide-receptor therapy with 90Y/77Lu-DOTA-TATE was commenced.
