Visualization of myocardial metastasis of carcinoid tumor by indium-111-pentetreotide.

Abstract

We present a case of metastatic carcinoid tumor metastatic to the heart, presenting as ventricular arrhythmia and diagnosed by 111Inpentetreotide scintiscan despite negative endocardial biopsy. The incidence and diagnosis of carcinoid heart disease is discussed, as well as the complementary role of high-resolution anatomical images (CT, MRI) with functional images (SPECT, PET) to determine the correct diagnosis of this rare condition.
