Example of sural nerve pathologies. A Long-axis view of the sural nerve in a patient with open leg trauma showing abrupt end of the nerve and a terminal hypoechoic swelling denoting complete nerve transection with formation of proximal stump neuroma. B Short-axis view of the sural nerve at lateral ankle just distal to the lateral malleolus in a patient with soft tissue swelling at the lateral ankle showing a well-defined hypoechoic non-compressible swelling with posterior acoustic enhancement and internal septa consistent with ganglion cyst. The cyst is located between the lateral dorsal and the lateral calcaneal branches of the sural nerve
