ABSTRACT

Diagnosis: gastrinoma

History: 85 yo male w/ h/o distant RCC s/p rt nephrectomy now w/ transaminitis.

Findings: On CT, gastrinomas are hypervascular and average 3-4 cm in diameter. In over one-half of cases, multiple lesions are present. Thickened gastric and small bowel folds may be present from increased gastric acid secretion and malabsorption. Approximately 60% of patients have metastases at the time of diagnosis, most often to the liver and lymph nodes. Islet cell tumors typically express somatostatin receptors, making them amenable to Octreoscan imaging where they demonstrate abnormally increased uptake of the radiotracer.

Ddx: Ductal adenocarcinoma Islet-cell tumor: insulinoma, gastrinoma, nonfunctioning, glucagonoma, somatostatinoma, VIPoma Lymphoma Metastases: melanoma, renal cell, breast, lung, stomach Solid and papillary epithelial neoplasm Mimics: peripancreatic adenopathy, adrenal mass, splenule Focal pancreatitis Idiopathic fibrosing pancreatitis Pancreaticoblastoma: children Acinar cell carcinma

Dxhow: surgery is pending

Exam: Gastrin 1416 (nl 0-42)

No MeSH data available.
