Images of patient #7. A 3-year-old girl with typical clinical manifestations of neuromuscular choristomas (NMC) of the sciatic nerve, including leg length discrepancy and calf muscles atrophy, and right foot shorter than the left foot (A). Ultrasound imaging demonstrated that the right sciatic nerve of the upper and middle thigh was hypoechoic and fusiformly enlarged. The cross-sectional area of the nerve was 0.68cm2 (B), and the diameter was 0.47 cm in the longitudinal section (C). Comparing with the other side, the size and echo intensity were normal in the left sciatic nerve (diameter 0.19 cm, cross-sectional area 0.23cm2) (D). Neither progression of NMC nor neuromuscular choristomas associated desmoid-type fibromatosis (NMC-DTF) was found during the 8-month follow-up
