Intraneural cysts are rare, benign tumors of the peripheral nerves that were first described by Zum-Bush in 1895. Its origin is characterized by the infiltration of the neural sheath by a mucoid substance that forms an intraneural tumor, compressing the nerve fascicles towards the periphery. There is no epithelial lining and the pathogenesis is controversial. A 58-year-old male with a history of health reported increased volume in the upper and lateral area of the right leg, without pain on palpation or mobilization, signs of present tinel, inability to dorsi(s) flexion and eversion of the foot manifested by steppage gait and hypoesthesia area at the level of the lateral aspect of the ankle and dorsum of the foot. Pain in the lateral area of the leg during walking and relieves during rest. Evolution of 3 months.
