[Orthopedic foot abnormalities as a important sign of lumbosacral spinal lipoma in an 11-year-old boy].

A case of an 11-year-old boy with giant lumbosacral spinal lipoma is presented. Hobbling on the left foot and its dropping was observed at the age of 9 after which left equinovarus foot and excavated foot deformities developed. Diurnal and nocturnal enuresis, infection of the urinary tract, and bilateral vesico-ureteral reflux were found. At birth, the patient had cleft palate and cleft upper lip, and bending of the interbuttocks groove, which is suggestive of occult spina bifida. It seems that in the case of orthopedic foot abnormalities developing in a previously healthy child, MRI investigation of the lumbosacral spine should be considered.
