# Perforated Rectal Cancer Presenting With Symptoms of Sciatic Nerve Compression: A Case Report

## TL;DR

This case report describes a rare instance of rectal cancer that spread to the sciatic nerve, causing leg pain and falls, highlighting diagnostic challenges.

## Contribution

The novelty lies in presenting an atypical clinical presentation of rectal cancer involving sciatic nerve compression.

## Key findings

- A case of locally advanced rectal cancer perforating into the greater sciatic notch was identified.
- The patient presented with lower limb pain and recurrent falls, mimicking sciatic nerve compression.
- The case emphasizes the difficulty in diagnosing unusual colorectal cancer presentations.

## Abstract

In this paper, we discuss the case of a late presentation, locally advanced rectal cancer that has perforated into the greater sciatic notch, presenting with symptoms of lower limb pain and recurrent falls. In this case, we discuss the complexities of diagnosing and managing atypical presentations of colorectal cancer.
