Intramuscular amyloidosis. Coronal T1-weighted MRI (A) demonstrating enlargement of the right inferior rectus muscle with areas of relative hyperintensity. Coronal T2-fat-suppressed MRI (B) shows enlargement and hypointense lesions of the right inferior rectus muscle (arrow). An axial fat-suppressed contrast-enhanced T1-weighted MRI (C) shows heterogenous pattern of enhancement of the right inferior rectus. Coronal fat-suppressed contrast-enhanced T1-weighted MRI (D) demonstrated a heterogenous pattern of enhancement, with areas of increased enhancement corresponding to T2-hypointense areas (arrow)
