Additionally, overriding of the 4th toe on the 5th and pes cavus were observed [Figure 1].
Magnetic resonance imaging of muscles of pelvis and thigh showing (a) T1-weighted coronal image showing fatty infiltration of bilateral adductors (adductor brevis and magnus), (b) T1-weighted axial image of pelvis showing bilateral fatty infiltration of gluteus minimus with sparing of gluteus maximus and medius, (c) T1-weighted axial image of pelvis showing bilateral fatty infiltration of pectineus and adductors, (d) and (e) T1-weighted axial image of thigh muscles showing fatty infiltration of bilateral adductor brevis and magnus with sparing of adductor longus and quadriceps

Muscle MRI showed fatty infiltration in bilateral gluteus minimus, adductor magnus and brevis, obturators, and pectineus with distinct sparing of the anterolateral compartment, which also correlated clinically [Figure 2].
