From: Nerve entrapment syndromes of the lower limb: a pictorial review
40-year-old man who had a skiing accident and sustained a high fibular fracture and syndesmotic injury. Soon after the injury, he presented with foot drop and symptoms of common peroneal nerve entrapment. CT at the level of the proximal fibula/calf shows periosteal new bone formation at site of the proximal fibular fracture (a). Sequential axial PDFS (b) and axial PD (c and d) sequences show the proximal superficial nerve (yellow arrows) and deep peroneal nerve (white arrows) shortly after the common peroneal nerve division. The deep peroneal nerve appears oedematous on the PDFS axial sequence. The superficial peroneal nerve appears oedematous, although to a lesser extent
