# A Rare Case of a Neuroendocrine Tumor With Intracardiac Metastasis: Management and Literature Review

## TL;DR

This paper reports a rare case of a neuroendocrine tumor that spread to the heart and discusses its management and existing literature.

## Contribution

The novelty lies in presenting a unique case of intracardiac metastasis from a pelvic neuroendocrine tumor.

## Key findings

- Neuroendocrine tumors rarely metastasize to the heart.
- This case highlights the potential for pelvic NETs to spread to the heart.
- The paper provides insights into the management of such rare metastases.

## Abstract

Neuroendocrine tumors (NETs) are rare neoplasms originating from the neuroendocrine system. While they can develop sporadically throughout the body, they are mostly found in the gastrointestinal tract, respiratory tract, pancreas, and thymus. NETs can be classified into low-grade indolent tumors, intermediate-grade tumors, or high-grade aggressive cancers. These tumors have the potential to metastasize to various parts of the body, with the liver being the primary site for metastases. However, it is extremely rare for NETs to metastasize to the heart. Here, we present a unique case of intracardiac metastasis from a pelvic NET in a 54-year-old male patient.
