# Acute Colonic Pseudo-Obstruction (Ogilvie’s Syndrome) Associated With Herpes Zoster Infection: A Case Report

## TL;DR

This case report describes a rare instance of acute colonic pseudo-obstruction caused by herpes zoster infection in an elderly patient.

## Contribution

The paper highlights the rare association between herpes zoster and Ogilvie’s syndrome, emphasizing the need for early recognition.

## Key findings

- Herpes zoster can cause acute colonic pseudo-obstruction, even in the absence of mechanical obstruction.
- Early antiviral therapy and supportive care led to clinical improvement in the reported case.
- Prompt diagnosis is crucial to prevent complications and improve outcomes.

## Abstract

Ogilvie’s syndrome is an uncommon but potentially serious condition characterized by colonic dilatation in the absence of mechanical obstruction. Although typically associated with postoperative states, trauma, or pharmacologic agents, its occurrence secondary to herpes zoster is exceedingly rare. In this case report, we present a 78-year-old male with generalized abdominal pain, abdominal distention, obstipation, constipation, and herpetiform rash. The treatment modalities include bowel rest, intravenous fluid therapy, and correction of any existing electrolyte imbalances, followed by the initiation of parenteral nutrition, nasogastric tube, and enemas to reduce the risk of complications. Pharmacologic treatment with antiviral therapy and neostigmine is used in select cases. Surgical management is indicated when both therapies fail or complications exist.

The purpose of this case report is to highlight the importance of considering herpes zoster as a rare but significant cause of acute colonic pseudo-obstruction. Early recognition and prompt initiation of antiviral therapy may lead to rapid clinical improvement and prevent complications.
