A 37-year-old male patient presented with acid reflux and vomiting and was later diagnosed with MEN1. (A) 99mTc-MIBI image of the right parathyroid gland was positive, which was pathologically confirmed as parathyroid adenoma. (B) Coronal contrast-enhanced T₁WI image showed a circular mass (arrow) in the left sellar with uneven and obvious enhancement. The lesion was pathologically confirmed as pituitary macroadenoma. (C) Axial contrast-enhanced CT image showed an enhanced nodule (arrow) in the duodenal bulb and the thickened left adrenal gland. Gastroscopy image showed a mucosal bulge (arrow) approximately 6 mm × 5 mm on the duodenal bulb. The lesion was pathologically shown to be a gastrinoma. (D) Axial contrast-enhanced CT image showed an enhanced nodule (arrow) in the neck of the pancreas. The somatostatin receptor scintigraphy was positive in the corresponding region. The lesion was pathologically shown to be a gastrinoma. MEN1, multiple endocrine neoplasia type 1; CT, computed tomography; T₁WI, T₁ weighted imaging.
