title: Ganglion cyst at the fibular head causing common peroneal neuropathy diagnosed with ultrasound and electrodiagnostic examination: a case report.
abstract: The common peroneal nerve is a major source of innervation to the lower limb, but it is sometimes compressed or entrapped at the fibular head. The authors present what they believe is the first reported case where peroneal nerve impingement caused by ganglion cyst compression of the nerve at the fibular head was diagnosed using a combination of ultrasound imaging and electrodiagnostic studies. The authors described the history, physical examination, electrodiagnostic findings, and musculoskeletal ultrasound findings of a patient with a left foot drop caused by a ganglion cyst compressing the common peroneal nerve at the fibular head. The increasing role of ultrasound imaging to evaluate musculoskeletal pathology is discussed.
