Abstract

Purpose. Tc-99m tetrofosmin launched for myocardial studies has recently also shown a good detectability for several tumors. Data on PNET imaging by Tc-99m tetrofosmin are not yet available.

Patient and method. In the case of a 21-year-old man suffering from pelvis PNET, Tc-99m tetrofosmin scintigraphy was performed additionally to CT and MRI.

Results. The gluteal and iliac tumor masses were visualized by Tc-99m tetrofosmin according to the CT and MRI results.

Discussion. Imaging with Tc-99m tetrofosmin could provide additional information to the available conventional radiological imaging modalities for diagnosis of PNET, and could be a useful tool for the restaging of the primary tumor.
