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.

Forty-two cases of perineurioma have been reported in the literature. This report adds the first intratemporal facial nerve perineurioma to the literature and reviews the others. Unlike schwannoma and neurofibroma, the histological features of perineurioma demonstrate onion bulb-like structures with a strong positive immunoreactivity for epithelial membrane antigen. The clinical history of gradual facial nerve paresis was 15 years in the case presentation and the clinical diagnosis of tumor was overlooked.

In this study, the authors present their experience of using extreme later transcondylar approach (ELTC) for treating 7 patients with lesions in the anterolateral foramen magnum, upper cervical spine and cerebellopontine angle reaching upto jugular foramen. The tumours included meningiomas, neurofibromas (2 cases each), chondrosarcoma, epidermoid and aneurysmal bone cyst (one case each). The approach was used alone, in combination with retrolabyrinthine presigmoid approach in a patient with lower cranial nerve neurofibroma extending extracranially through the jugular foramen, or in combination with partial C1-C3 laminectomy in two patients with meningiomas situated anterolateral to the cord from the foramen magnum to C3. In two patients with extradural vertebral artery (VA) entrapment by a chondrosarcoma and aneurysmal bone cyst respectively, the vertebral artery was ligated distal to the tumour. The tumours were totally excised in five cases and partially in two. There was no preoperative mortality. The major complications included cerebrospinal fluid leak from the wound (3 cases) and increase in lower cranial nerve paresis (2 cases). At follow up, ranging from 6 months to 2 years, 5 patients showed no tumour recurrence. There was improvement in neurological status. One patient, with a partially excised aneurysmal bone cyst, showed no added deficits or increase in the tumour size. However, there was a massive regrowth in the patient with chondrosarcoma after 6 months. This technique provided a wide surgical exposure with direct visualization of the tumour-anterior cord interface, early proximal control of the VA and preservation of lower cranial nerves.

The incidence of solitary neurofibroma of the facial nerve originating in the parotid region is extremely low. We report a case of a solitary neurofibroma in a 30-year-old male, who initially presented with a parotid mass without facial paresis or paralysis. A chain of small nodules had been palpable in the right parotid region for the previous 2-3 years. MRI and CT scans revealed several small ovoid lesions extending from the frontal margin of the parotid gland to the retromandibular region. The lesions were surgically removed. The main trunk of the facial nerve was adherent to the dorsal side of the largest nodule; however, this mass was resected atraumatically. Histopathological examination indicated neurofibroma. The incidence, presentation, diagnosis and surgical treatment of intraparotid neurofibroma are discussed and compared with those of Schwannoma.

The objective of the study was to evaluate the dependence of facial nerve paresis, as a symptom of cerebellopontine angle tumour, on the histopathological subtype of vestibular schwannoma, diagnosed from a post-operative histopathological examination. We retrospectively analysed 91 surgically treated patients with vestibular schwannoma. We studied the histopathological subtype and the preoperative condition of the facial nerve. The following WHO 2000 subtypes were distinguished: neurinoma cellular (51 cases), neurinoma conventional (23 cases), neurinoma ancient (11 cases), (other types: 2 neurofibroma and 2 ganglioneuroma). We analysed the dependence of facial nerve paresis on the histological subtype of tumours and their sizes. The analysis was based on the traditional classification: Antoni A (11 cases), Antoni B (12 cases) Antoni A/B (23 cases) and Antoni B/A (40 cases). 30 patients (30%) in the analysed group had paresis of the facial nerve preoperatively. Preoperative facial paresis occurred frequently in subtypes "cellular" and Antoni B, and rarely in subtypes conventional and Antoni A and B/A. In the small tumour cases (up to 20 mm), facial nerve paresis occurred frequently in subtypes cellular and conventional, as well as in Antoni A and A/B.

Although lateral popliteal sciatic nerve damage is not one of the commonest diseases in the general population, it is quite frequent among athletes. Several physiopathologic mechanisms have been thought to bring about this damage in athletes. Soft tissue ganglions with neurological involvement of the lateral popliteal sciatic nerve or its terminal rami are in differential diagnosis with several lesions of this area, as direct or indirect trauma, subcutaneous rupture of anterior tibialis muscle and long peroneal muscle, disc hernia, intraspinal tumor, anterior tarsal tunnel syndrome, cysts, neurofibroma, baker's cyst, vascular claudication, stenosing or inflammatory pathology of 2(nd) motoneuron, antimicrobial agents for urinary tract infection (nitrofurnantoin). The authors report the case of a 34-year-old amateur athlete with a recent paralysis of the hallux extensor, paresis of the toe extensor and hyposthenia of the tibialis anterior. The patient had been suffering from episodes of lumbalgia for a long time. He was sent to us because neurological damage due to disc herniation was suspected. Electromyography, sonography, and CT showed peripheral compression of the deep peroneal nerve caused by a mucous cyst at the capitulum peronei, a ''rare'' condition. The patient underwent surgery to excise the cyst, which led to the rapid resolution of the nerve deficit shown by clinical and electromyographical tests. A meticulous anamnesis and accurate objective examination, followed by specific tests (radiographs, sonography, and possibly CT scan) generally enable a correct diagnosis to be made. If diagnosis and therapy are carried out correctly, and without delay, symptoms quickly resolve and the nerve deficit progressively regresses.
