# Meckel's diverticulum: A rare and missed cause of adult gastrointestinal bleed

## TL;DR

This paper reports a rare case of gastrointestinal bleeding in an adult caused by Meckel's diverticulum, emphasizing the need for varied diagnostic approaches.

## Contribution

Highlights the rare occurrence of Meckel's diverticulum as a cause of adult gastrointestinal bleeding and the diagnostic utility of technetium-99m imaging.

## Key findings

- Meckel's diverticulum can cause gastrointestinal bleeding in adults.
- Technetium-99m pertechnetate scintigraphy with SPECT/CT was effective in diagnosing the condition.
- Conventional diagnostic tests failed to identify the cause of bleeding.

## Abstract

Our report details a rare case of gastrointestinal bleeding in an adult male from Meckel's diverticulum. Diagnostic tests were negative except for technetium‐99m pertechnetate scintigraphy with SPECT/CT, highlighting importance of diverse modalities.
