A ganglion cyst is the cystic lesion originates from the joint capsule or tendon sheath. This lesion
is the most common soft tissue tumors of hand, wrist, and foot, and frequently observed in
women between 30-50 years. A peroneal ganglion cyst is an uncommon lesion and rarely composes
peroneal neuropathic symptoms. We report a 37-year-old man with swelling at the lateral
portion of knee below, foot pain, loss of sensation at the lateral portion of left inferior cruris.
Ultrasound (US) and magnetic resonance imaging (MRI) findings demonstrated a large cystic
lesion in the peroneal muscle, and preliminary diagnosis of peroneal ganglion cyst was proved
by cytology. The patient was asymptomatic one month after surgery. There was no evidence of
residue or recurrence on US imaging after 6 months.
