Idiopathic eosinophilic myositis can cause painful upper arm swelling. Magnetic resonance (MR) imaging showed muscle enlargement and edema, which resolved spontaneously without treatment.

Area of Science:

Musculoskeletal Imaging
Rheumatology
Neurology

Background:

Idiopathic eosinophilic myositis is a rare inflammatory condition affecting skeletal muscles.
It typically presents with pain, swelling, and weakness.

Observation:

A case of idiopathic eosinophilic myositis in the upper arm was evaluated using magnetic resonance (MR) imaging.
The patient presented with painful swelling of the upper arm.

Findings:

MR imaging revealed diffuse enlargement and edema of the triceps muscle.
An ill-defined, heterogeneous mass was noted within the muscle's midportion.
Adjacent fascial edema was also prominent.

Implications:

This case highlights the characteristic MR imaging findings of idiopathic eosinophilic myositis.

The spontaneous resolution observed suggests a potentially self-limiting nature of the condition in some cases.

Understanding these imaging features is crucial for accurate diagnosis and management of eosinophilic myositis.
