What are the characteristic MRI findings of the thighs in patients with spinal muscular atrophy Type II?
MRI of the thighs in SMA Type II demonstrates a characteristic pattern of severe atrophy and fatty infiltration with selective preservation of the adductor longus, gracilis, and sartorius muscles.
We present magnetic resonance (MR) findings of siblings affected by spinal muscular atrophy (SMA) Type II. MRI of their thighs showed severe muscle atrophy and fatty infiltration. Selective preservation of the adductor longus muscle, the gracilis muscle, and the sartorius muscles was observed, suggesting a characteristic finding of SMA Type II. These findings were more severe in the older patient.

Ueno et al. (2003) conducted a case report in Spinal Muscular Atrophy Type II (n=2). Magnetic Resonance Imaging (MRI) was evaluated on Muscle atrophy and fatty infiltration on MRI. MRI of the thighs in two siblings with SMA Type II revealed severe muscle atrophy and fatty infiltration, with selective preservation of the adductor longus, gracilis, and sartorius muscles.
