Findings: SOMATOSTATIN-RECEPTOR SCINTIGRAPHY (WITH TOMOGRAPHIC IMAGING) RADIOPHARMACEUTICAL: 6.0 mCi In-111 pentetreotide i.v.
There are two distinct populations of liver lesions. There are multiple low attenuation hepatic lesions with increased tracer accumulation. There are two large low-attenuation lesions which have less tracer accumulation than normal liver parenchyma.
There is an approximately 2.5 x 2.0 cm soft tissue density mass in the terminal ileum at the ileocecal valve with increased tracer uptake.
COMPUTED TOMOGRAPHY OF THE ABDOMEN AND PELVIS There are multiple lesions seen throughout the liver. Some of the hepatic lesions demonstrate hyperenhancement, while others demonstrate hypoenhancement.
There is a 2.4 cm hyperenhancing mass at the ileocecal valve.
There is eccentric wall thickening of the rectum, anteriorly concerning for rectal mass. This mass is measures approximately 2 cm in axial dimension and 3 cm craniocaudally. This mass is seen approximately 3 cm superior to the anal verge. |
Diagnosis: Well differentiated rectal adenocarcinoma with hepatic metastasis.
Well differentiated neuroendocrine carcinoma hepatic metastasis, with a probable terminal ileum primary. |
