# Case Report: Imaging and pathological analysis of intra-abdominal aggressive fibromatosis with abscess

## TL;DR

This case report describes a rare instance of intra-abdominal aggressive fibromatosis complicated by an abscess, highlighting its imaging and pathological features for better diagnosis.

## Contribution

The novelty lies in presenting a rare case of IAF with abscess, offering insights into its imaging and pathological characteristics.

## Key findings

- IAF with abscess is rare and presents diagnostic challenges due to nonspecific imaging features.
- Combining imaging and pathological analysis improves diagnostic accuracy for IAF.
- Early recognition and appropriate treatment are crucial for managing IAF with complications.

## Abstract

This study investigates the imaging diagnosis and differential diagnosis of intra-abdominal aggressive fibromatosis (IAF) complicated by acute infection. Aggressive fibromatosis is a rare mesenchymal tumor of unclear etiology, potentially associated with genetic factors, hormonal levels, trauma, and other factors. Due to its clinical rarity and nonspecific imaging manifestations, preoperative diagnosis is challenging and prone to misdiagnosis, particularly in the more complex presentation of IAF. We present a rare case of IAF accompanied by abscess formation, analyzing its imaging and pathological features alongside clinical manifestations, and discuss diagnostic and therapeutic strategies.
