Figure 4. Magnetic resonance imaging with i.v. gadolinium contrast images of the left shoulder showing a 2.7×2.5×3.7 cm oblong mass with the inferior deltoid muscle. (A) Coronal T2 with fat suppression image (* intramuscular mass, ~ deltoid tendon, × humeral head). (B) Axial PD with fat suppression (* intramuscular mass, ~ deltoid tendon, × humeral head). Within the inferior deltoid muscle is an oblong mass-like signal abnormality which is T1 hypo- and T2 hyperintense, measuring approximately 2.7×2.5×3.7 cm. Post-gadolinium sequences demonstrate heterogeneous regions of predominantly peripheral enhancement.
