Abstract
This report presents a case of malignant granular cell tumor in the deltoid muscle and emphasizes the correlation between magnetic resonance (MR) images and pathological findings. A 71-year-old woman developed an elastic hard mass at the left shoulder. MR images revealed a soft tissue tumor with a maximum diameter of 5 cm and low signal intensity on both T1- and T2-weighted images. The lesion with decreased signal intensity on all the images correlated with marked fibrosis mimicking desmoid tumor. Contrast-enhanced MR images provided useful information regarding the choice of biopsy site.
