Image:Metastasis in MEN 2.jpg|Spiral abdominopelvic CT scan (with contrast). The report was as follows. Multiple calcified and noncalcified lesions in liver are seen (metastasis should be considered). Some of the small bowel loops have thickened wall. Mild right side hydronephrosis is present. Anterior abdominal wall fistula is depicted. A few small paraaortic lymphnodes are seen. Mild left side pleural effusion and massive ascites were also noted.

Overview

Neck CT scan may be helpful in the diagnosis of multiple endocrine neoplasia type 2. Findings on CT scan suggestive of multiple endocrine neoplasia type 2 include irregular dense calcific foci within thyroid, ectopic mediastinal gland, and heterogeneous masses with areas of necrosis within adrenal gland.

CT

Medullary Thyroid Carcinoma

Parathyroid Carcinoma

Enhancement on 4D-CT

  • On 4D-CT parathyroid adenomas typically demonstrate intense enhancement on arterial phase, washout of contrast on delayed phase and low attenuation on non-contrast imaging.
  • Secondary signs include the following:

Pheochromocytoma
