RETRACTED: An unusual cause of paralysis of the peroneal nerve: a report of 3 cases

We present 3 cases of a 12-year-old boy, an 8-year-old girl, and a 9-year-old boy with progressive paresis of the peroneal nerve. Peroneal intraneural ganglia are a rare cause of paralysis of the lower limb in children; more often these symptoms occur because of exostosis. Ultrasound imaging in both patients showed a cystic mass near the fibular neck. Magnetic resonance imaging examination revealed that the ganglion is communicating with the proximal tibiofibular joint. Surgical exploration in these patients confirmed a cystic formation involving the common peroneal nerve. The ganglion originates from the articular nerve branch to the proximal tibiofibular joint. Total recovery of nerve function was seen 2 years later for the first patient, whereas the other 2 showed immediate postoperative improvement of peroneal nerve function and complete recovery within 6 to 8 weeks. On the other hand, patients with exostosis showed varying outcomes. In children with symptoms suspicious of nerve compression, fast diagnosis and immediate treatment are necessary to ensure the best possible recovery.
