cze Maligní schwannom nervus obturatorius Léze nervus obturatorius jsou vzácné, nádory a zvláště maligní schwannom tohoto nervu je extrémně vzácný. Autoři popisují vzácný případ gigantického schwannomu nervus obturatorius u 69ti leté pacientky. Kvůli expanzi v proximální části stehna bylo provedeno RMI vyšetření které prokázalo extenzivně rostoucí tumor vycházející z nervus obturatorius. Pacientka neměla neurologické projevy. K navazující péči byla referována na onkologii a radioterapii. Cílem tohoto sdělení je poukázat na extrémní vzácnost výskytu tumorů toho nervu a navrhnout možnosti terapie. léze nervus obturatorius; maligní schwannom; MPNST
eng Malignant schwannoma of the obturator nerve Lesions of obturator nerve are rare. Tumours and mainly malignant schwannoma of this nerve are extremely rare. The authors describe an unusual case of a gigantic schwannoma of the obturator nerve in 69 year old woman. Due to tumour expansion in the proximal part of the thigh MRI was performed and demonstrated extensive tumour originating most probably from the obturator nerve. The patient had no neurological symptoms. Biopsy from the lesion was taken at the Department of Orthopaedics with the following conclusion: malignant schwannoma. The patient received neoadjuvant chemotherapy due to diffuse metastatic spread on the chest X ray, after which metastatic spread subsided. The main lesion reduced its size by 1 cm. In 4 months after biopsy the patient was referred for operation to neurosurgery. The tumour was removed along its borders and except of minimal weakness of adduction of the right thigh there was no neurological deterioration. She was subsequently referred for further care to oncology and radiotherapy. The goal of this work is to emphasize the extremely rare occurrence of tumours of this nerve and suggest therapeutic options (Fig. 4, Ref. 11). obturator nerve lesion; malignant schwannoma; MPNST
