[Solitary neurofibroma of the lumbosacral plexus. Case report]

The article describes a case of a solitary neurofibroma of the plexus lumbosacralis causing pain and incomplete leg paresis. Complete relief was obtained by total extirpation of the tumour, a procedure which must be regarded as the method of choice. Pain and pareses in the lower extremities require differential diagnostic consideration of rare neurogenic tumours of the peripheral nervous system in the regions of the pelvis and plexus lumbosacralis. Neurological examination by a specialist is of significant importance preoperatively to determine the seat of the tumour and to assess the postoperative course.
