We describe a schwannoma of the obturator nerve in a woman 66 years old. It was diagnosed only postoperatively because of the aspecificity of the symptoms. The difficulty of making a correct diagnosis during surgery is discussed, and the potential serious consequences of total excision of the nerve are described.

    ABSTRACT: Schwannomas are usually benign tumors that arise from a nerve supporting the Schwann cells, those are mostly associated with the cranial or main peripheral nerves. The occurrence of retroperitoneal schwannoma is quite rare, and in such a case, surgical excision is the first option for treatment. In 1996, Melvin1 confirmed the feasibility of the complete resection of a retroperitoneal schwannoma using laparoscopy for the first time. Until recently, only few cases of laparoscopic resection of retroperitoneal schwannoma have been reported.

    ABSTRACT: A nine-year-old female Rottweiler presented with a 6-week history of progressive impairment of hindlimb adduction. Clinical examination showed abduction of both hind legs when walking on a smooth surface, pain at the medial surface of the left thigh, and an intrarectal palpable mass at the pelvic floor. Electromyography demonstrated fibrillation potentials in the adductor muscles on both sides. Pelvic radiographs showed severe osteolysis of the ischium. Gross post-mortem examination following euthanasia disclosed a large retroperitoneal mass, invading the obturator foramina and compressing both obturator nerves. Histopathological examination revealed a high-grade anaplastic sarcoma. Immunohistochemically, the tumour cells labelled positively for vimentin and alpha-smooth muscle actin, hence the tumour was considered a "myofibroblastic fibrosarcoma". This unique case report describes a novel cause of obturator neuropathy in veterinary medicine. To date, clinical descriptions of obturator nerve lesions have been limited to pelvic fractures in small animals and following difficult labour in large animals.
