Abstract Intraneural lipomas are typically found within the epineurium of a nerve. Several cases of intraneural lipomas of the upper extremity have been reported, mostly related to the median nerve, but only a few cases involving the sciatic and tibial nerves have been described, due to the low incidence of these lesions in the lower extremity. Here we describe, possibly, the first case of a large intraneural lipoma with involvement of both common and superficial peroneal nerves in a 59-year-old woman. We would like to discuss management and long-term outcomes of this unique tumor, along with our observations during a follow-up period of 3 years. Level of evidence: Level II, diagnostic; therapeutic study. Keywords Common peroneal nerve . Compression . Intraneural lipoma . Lower extremity
Introduction Adipose tumors are common soft tissue tumors, predominantly occur in female patients, and show greater incidence during the 4th and 5th decades of life. Lesions are commonly located in the shoulders, the trunk, the extremities, the upper arms, and the neck, but are rarely found in hands and feet [1]. Even though they are commonly seen, they rarely affect peripheral nerves. Their etiology involves two different mechanisms that are based on the relationship between the epineurium and adipose mass. Extraneural lipomas arise outside the nerve; these can cause external compression of the epineurium and secondary neuropathy due to

a mass effect. In contrast, intraneural lipomas have encapsulated adipose tissue within the epineurium. As the adipose tissue is usually a component of the nerve, it can cause neuropathy due to mass effect [1, 2]. Intraneural lipomas are rare with unknown etiology, but quite a few cases have been reported thus far. The lesion is composed of homogeneous fibro–fatty tissue without any neural tissue, and it can cause interfascicular separation of the affected nerve. Furthermore, due to compression of the nerve, intraneural lipomas usually manifest as tingling sensations, pain, hypoesthesia, and motor function deficits [3]. Intraneural lipomas are mostly seen in the median nerve within the carpal tunnel. Alternative locations include the radial, ulnar, musculocutaneous, axillar, suprascapular, common peroneal, superficial peroneal, sciatic, tibial, and posterior interosseous nerves, as well as the brachial plexus [2, 3]. Here, we describe a case of a huge intraneural lipoma involving the common and superficial peroneal nerves. To the best of our knowledge, such a case has never been described previously.
