MRI of thighs was performed by T1 and T2 weighted images in multiple planes. T2 weighted Fat suppressed sequence was obtained in coronal plane.
Present study reveals areas of increased signal intensity noted involving all the muscle groups in the coronal fat suppressed sections under review namely the adductor group, hamstrings, gluteal muscles and bilateral psoas muscles.
These muscles appear normal in size and shape. These muscles appear isointense on T1 weighted images (not shown) with preservation of the intermuscular cleavage planes. Overlying subcutaneous fat show normal signal intensity. The visualized bones under review show normal signal intensity. Both the hip joint spaces are intact.
