MRI detection of cysts of the knee causing common peroneal neuropathy.
In 10 consecutive patients with footdrop due to common peroneal neuropathy without an obvious cause, MRI of the knee showed pathology at the fibular head in 6, including 5 patients with clinically unsuspected cysts of the tibiofibular joint. All 6 of the patients improved with surgery.
