C Jackman, D Sokol, K Applegate, K Kayes, W Mahmud. Foot Drop Due To Peroneal Ganglion Cyst In An Adolescent. The Internet Journal of Neurology. 2004 Volume 3 Number 2.
Nerve compression by a ganglion is rare in children. Compression of the peroneal nerve by a ganglionic cyst causing foot drop is reported in an adolescent male.
A 14 year-old male tennis player presented with a gradually progressive left foot drop. Three weeks prior, he found a knot behind his left knee that resolved. Sagital MRI T2-weighted images of the left knee demonstrated a lobulated, cystic mass, antero-lateral to the fibular head. Upon excision, a ganglion cyst was found to be compressing the common peroneal nerve. The child recovered at three months.
Nerve compression by a ganglion is rare in children (1). Rapid, repetitive actions involving acceleration/deceleration have been theorized to predispose ganglion cyst formation (2).
