case_images: F1
case_images: She was unable to squat with her knees together, which forced her to assume a "frog position" when doing so (Fig. 1), and was unable to cross her legs.
case_images: MRI reveals T1-weighted (A) and T2-weighted (B) images, showing significant atrophy of the bilateral gluteus medius, with a low-intensity band within this muscle on both T1- and T2-weighted images (indicated by arrows). These muscular changes are more prominent in the left thigh than in the right. MRI = magnetic resonance imaging.
