# Arterial embolization in the treatment of multiple renal and hepatic hamartomas with spontaneous hemorrhage and 2-year follow-up: a case report

## TL;DR

A 46-year-old woman with multiple kidney and liver hamartomas that bled was successfully treated with repeated arterial embolizations over two years.

## Contribution

This case report demonstrates the effectiveness of repeated arterial embolization in managing multiple bleeding hamartomas over a long-term follow-up.

## Key findings

- Arterial embolization rapidly controlled acute hemorrhage from a giant renal hamartoma.
- Repeated embolizations effectively managed multiple lesions over a 2-year period.
- The patient remained stable during follow-up, suggesting long-term efficacy of the treatment.

## Abstract

Hamartoma is a common benign tumor that usually occurs in the kidney, liver, lung, and pancreas. Large renal hamartomas may spontaneously rupture and hemorrhage, which is potentially life-threatening.

This report describes a 46-year-old Han Chinese female patient with multiple renal and hepatic hamartomas with rupture and hemorrhage of giant hamartoma in the left kidney. She underwent arterial embolization three times successively, and her condition was stable during the 2-year follow-up. This report includes a review of the relevant literature

the findings in this report and previous literature suggest that arterial embolization can not only rapidly treat hamartoma hemorrhage in the acute phase but can also effectively control multiple lesions in the long term after repeated multisite arterial embolization.
