2. CASE REPORT
A 60-year-old female presented to Najmiyeh hospital (a hospital in
Tehran), with edema, progressive pain in the anterior-proximal side of
the right forearm, palpation of well-defined masses with a high growing
rate and movement limitation during forearm flexion. During physical
examination, it was found that the mobile tumor mass with specific
boundaries was inside the supinator muscle (anterior aspect of elbow
joint) and did not have any inflammatory or secretion symptoms.
Evaluation of the lesion with sagittal and coronal MRI T2-weighted
sections showed that the 3.5 × 2.5 × 2 cm well-defined high signal mass
was observed in the antero-proximal elbow joint and inside the supinator
muscle (Figure1 and 2).
