## TL;DR

A rare case of chronic eosinophilic leukemia with a PDGFRA gene rearrangement presented with symptoms resembling vestibular neuritis in a 53-year-old man.

## Contribution

This case highlights a rare presentation of chronic eosinophilic leukemia associated with a PDGFRA gene rearrangement.

## Key findings

- The patient exhibited symptoms of vestibular neuritis linked to chronic eosinophilic leukemia.
- A PDGFRA gene rearrangement was identified in the patient's leukemia cells.

## Abstract

Myeloproliferative neoplasms are disorders of stem cells that result in excessive proliferation of one or more myeloid progenitors. We report a rare finding of chronic eosinophilic leukemia with a rearrangement of the PDGFRA gene in a 53‐year‐old male patient presenting with symptoms suggestive of vestibular neuritis.
