GUEDES-CORREA, José F.; AMORIM, Rogério Pires de; MEGALI, Raquel  and  SIQUARA, Ana Moura. Mononeuropatía hipertrófica localizada: reporte de un caso y revisión de la literatura. Rev. argent. neurocir. [online]. 2010, vol.24, n.2, pp.67-70. ISSN 1850-1532.

The authors report the case of a 39 year-old female, who presented with 10 years history of intense progressive pain, hypoesthesia in hypotenar region and motor deficit in the left hand. The physical exam showed hypotenar muscles atrophy, "claw hand", and Tinel's sign in the forearm (8 cm distal from the medial epicondyle). Magnetic resonance imaging showed a mass lesion along ulnar nerve path in the forearm. Surgical treatment was, then, suggested. Nerve conduction could not be registered during intra-operative stimulation. Microsurgical resection of the damaged nerve fascicles and sural nerve grafting were performed. Histopathological diagnosis was difficult and could only be confirmed as localized hypertrophic mononeuropathy after revision of the biopsied material. The patient is being followed up and she is showing signs of hypoesthesia improvement in addition to complete remission of the pain.

Keywords : Mononeuropathy; Ulnar nerve.
