37-year-old male with MEN 1. The patient was injected with 6.4 mCi In-111 octreotide, and images were acquired in the anterior and posterior projections at 4 hours (3A) and 24 hours (3B). SPECT images were also obtained at 24 hours (3C, axial, and 3D, coronal). Findings are consistent with metastatic somatostatin-receptor-positive malignancy involving the lymph nodes either in the peripancreatic or porta hepatis region. In addition, diffusely increased radiotracer uptake in the neck likely corresponds to the parathyroid pathology seen on the prior parathyroid scan.
