# Meningitis Retention Syndrome With Mild Encephalopathy With a Reversible Splenial Lesion in a 30-Year-Old Woman: A Case Report

## TL;DR

A 30-year-old woman presented with a rare combination of meningitis retention syndrome and a reversible brain lesion, highlighting the importance of a multidisciplinary approach for diagnosis and treatment.

## Contribution

This case report presents a rare adult case of MRS with MERS, offering insights into its clinical features and management.

## Key findings

- The patient exhibited fever, urinary retention, and leg weakness, with MRI showing a reversible splenial lesion.
- Blood and cerebrospinal fluid tests supported the diagnosis of MRS with MERS.
- A multidisciplinary approach was crucial for accurate diagnosis and effective treatment planning.

## Abstract

We describe a 30-year-old woman who had meningitis retention syndrome (MRS) with mild encephalitis/encephalopathy with a reversible splenial lesion (MERS), which occurred with fever, urinary retention, and weakness in both legs. A case of MRS with MERS is rare among adults, and its clinical course and treatment planning remain unknown. In the present, we highlighted the change in magnetic resonance imaging, blood tests, and cerebrospinal tests along with the treatment. A multidisciplinary approach by a radiologist and neurologist led to the diagnosis and appropriate treatment.
