# Cauda Equina Cavernoma: A Case Report and Literature Review

## TL;DR

This paper reports a rare case of a cavernoma in the cauda equina and reviews existing literature on similar cases.

## Contribution

The novelty lies in presenting a new case and consolidating existing knowledge on the extremely rare condition of cauda equina cavernomas.

## Key findings

- A 69-year-old woman with a cauda equina cavernoma was successfully treated with surgery.
- Literature review highlights the rarity and clinical features of cauda equina cavernomas.
- MRI and histological confirmation are key for diagnosis and management.

## Abstract

Cavernous hemangiomas (or cavernomas) are benign vasculature malformations that occasionally occur in the central nervous system (CNS). The vast majority is found supratentorial, but cavernomas also appear on the spine, usually intramedullary. Cavernomas in the cauda equina are extremely rare, with only a few cases reported in the literature. We report a case of a cavernoma of the cauda equina in a 69-year-old woman with low back pain and right sciatica for two years. Lumbar MRI showed an intradural mass lesion at the L1-L2 level. She underwent surgery with resection of the lesion, which confirmed the diagnosis of cavernous hemangioma. A good clinical outcome was achieved. In addition to the case report, we present a literature review on all reported cauda equina cavernomas, discussing their clinical presentations, imaging characteristics, histological findings, and surgical management.
