## Contribution

The paper presents a real case to help distinguish Miller Fisher Syndrome from myasthenia gravis for timely treatment.

## Key findings

- A 33-year-old female was initially misdiagnosed with myasthenia gravis but later found to have MFS.
- Key differences in symptoms can aid in early diagnosis of MFS.
- Early identification of MFS is crucial for timely treatment.

## Abstract

Miller Fisher syndrome (MFS) and myasthenia gravis can present with similar symptoms. However, some key differences can help differentiate between these two disorders. Early identification is extremely important for MFS so treatment can be initiated in a timely manner. Here, we present the case of a 33-year-old female who was initially diagnosed with myasthenia gravis and was later found to have MFS. The goal of this case report is to provide information to aid in the early diagnosis and identification of MFS.
