# An Unusual Presentation of Jejunal Diverticulitis Mimicking Acute Cholecystitis

## TL;DR

A rare case of jejunal diverticulitis was mistaken for acute cholecystitis due to similar symptoms and low platelet count.

## Contribution

This case highlights the under-recognized association between jejunal diverticulitis and thrombocytopenia.

## Key findings

- Jejunal diverticulitis can present with right upper quadrant pain and elevated white blood cell count.
- Thrombocytopenia may accompany jejunal diverticulitis and improve with non-operative management.

## Abstract

Jejunal diverticulosis is a rare entity and jejunal diverticulitis is even rarer. Here we review a patient who presented with right upper quadrant pain and elevated white blood cell count, mimicking acute cholecystitis, as well as thrombocytopenia (21x10^3/mcl). The patient was managed non-operatively with antibiotics and had improvement in symptoms and thrombocytopenia. Our study highlights the importance of maintaining jejunal diverticulitis in the differential for right upper quadrant pain, and its association with severe thrombocytopenia.
