# Rare case of “bullet” thrombus in the inferior vena cava

## TL;DR

This paper reports a rare case of a calcified thrombus in the inferior vena cava of an adult woman and discusses the diagnostic and treatment challenges it posed.

## Contribution

The novelty lies in describing a rare adult case of bullet thrombus and highlighting the lack of established treatment guidelines for this condition.

## Key findings

- A 44-year-old female was diagnosed with a bullet thrombus in the inferior vena cava.
- The condition was managed through surgical intervention due to diagnostic and therapeutic challenges.
- The rarity of the condition means there are no established clinical guidelines for treatment.

## Abstract

A bullet thrombus, characterized as an isolated calcified thrombus predominantly localized at the confluence of the renal veins in the inferior vena cava, is a rare clinical finding more commonly seen in pediatric patients than adults. The aetiology of bullet thrombi remains unclear. This report describes a 44-year-old female diagnosed with a bullet thrombus in the inferior vena cava, detailing the challenges encountered and the surgical intervention. The presence of a calcified thrombus in this region is typically an incidental discovery and complicates therapeutic decision-making, as there are currently no established guidelines due to the condition’s rarity.
