The Gamma Knife radiosurgical treatment of 20 patients suffering from trigeminal neuralgia is reported. Eleven patients received radiosurgical treatment with the goal of pain relief. Six had secondary trigeminal neuralgia due to AVM, large cavernous sinus and petrous bone meningiomas, trigeminal neurinoma, or chordoma; 5 others had essential trigeminal neuralgia. Radiosurgical treatment was considered only after the failure of conventional medical and surgical treatment. For the other 9 patients, the control of the tumor was the main objective (four acoustic and one trigeminal neurinoma, one petroclival chordoma, and three tumors of the cavernous sinus: one hemangiopericytoma, one metastasis, one meningioma). We have not been using this method for sufficient time to evaluate long-term results. However, we believe that a large majority of our patients benefited greatly from this technique with a rapid clinical improvement, which is a reflection of the relevance of the chosen target.

A 55-year-old male presented complaining of pain at his right fourth toe and dorsal fourth web space. Physical examination findings pointed to a lesion affecting the superficial peroneal nerve. A schwannoma of the superficial peroneal nerve was subsequently excised, relieving the patient's symptoms. In the differential diagnosis of nontraumatic and/or nonarthritic toe and foot pain, benign tumors, including schwannomas of the tibial and peroneal nerves, should be considered.

Clinical and pathological findings in 33 cases of brachial plexus neurinoma are reported. In 30 cases (90.91%) the diagnosis was proved to be correct by postoperative histological sections, and in other 3 cases (9.09%) the diagnosis couldn't be made preoperatively. The 33 cases were subjected to surgical resections and 18 (54.55%) of them still felt numbness and pain within two weeks after surgery. Sixteen cases were followed up for three months and 14 (87.5%) of them felt numbness by percussion over the incision. All the 33 cases had no brachial plexus traumatic complication postoperatively.

Schwannomas are benign nerve sheath tumors that most commonly occur singularly in otherwise normal individuals. Multiple schwannomas in a single patient are most often seen in neurofibromatosis 2 (NF2), but several recent reports suggest that schwannomatosis may also be a distinct clinical entity. We studied the clinical, radiographic, and pathologic features of 14 patients with multiple schwannomas who did not have vestibular schwannoma diagnostic of NF2. Most patients had peripheral nerve tumors that presented with pain. Many also had spinal nerve root and cranial nerve tumors. Three had multiple tumors limited to a single limb. We found that these 14 individuals did not exhibit phenotypic overlap with the neurofibromatoses. Only 1 of 14 patients had a positive family history. We conclude that patients with multiple schwannomas, who do not have vestibular schwannoma, comprise a distinct clinical problem, but further molecular genetic analysis is needed to define the pathophysiology of this disorder.

We report herein the case of a 62-year-old woman who presented to our hospital for investigation of occasional pain in her left breast. Although there was no mass palpable in her left breast, mammography and ultrasonography revealed a round tumor in the upper outer quadrant of the right breast. Although the mammography findings indicated that the tumor was benign, the possibility of a malignant neoplasm could not be ruled out by the ultrasonographic images. A final diagnosis of schwannoma was established by histopathological examination of the excised mass.

Between 1991 and 1994, 582 operations were performed in our service; 19 (3.26%) were on primitive tumors of the chest wall. We analyze the data for these patients, including age, sex, clinical findings, chest images, diagnoses, therapy and course. Ten tumors were benign and 9 were malignant. The most frequent clinical findings were pain and/or tumor. Diagnosis was achieved before surgery in only 2 cases. Except when there are clear macroscopic and X-ray signs that the tumor is benign, we performed broad exeresis of the chest wall, sometimes also resecting adjacent structures. The defect was repaired directly in 12 cases. The defects were covered by prostheses and/or muscle plasty in the remaining patients. The most frequent tumor was chondrosarcoma (3 cases), followed by 2 cases of osteoblastoma and osteochondroma. Only 1 each of the following tumors were found: plasmocytoma, chondroma, fibrous dysplasia, eosinophilic granuloma, osteosarcoma, Ewing's tumor, epithelioid sarcoma, fibrosarcoma, hemangioma, benign neurilemmoma, desmoid tumor and liposarcoma. Two patients with chondrosarcoma were operated on for recurrences and there was also recurrence in the patient with Ewing's tumor. We conclude that: 1) chest wall tumors are infrequent, 2) radical exeresis is the treatment of choice and prosthesis is often necessary, and 3) chondrosarcoma, with poor outcome in our patients, is the most frequent tumor.

Schwannomas are extremely rare tumours deriving from cells within the neurilemma. The authors report a case of giant intrasacral schwannoma presenting in the presacral region. The tumour presented with a lumbosacral pain and it was removed totally by two-stage surgical intervention. When seen five years after the second surgical intervention, the patient was asymptomatic. The rarity of such cases prompted this report.

A rare case of radicular pain in the arm due to compression of the C6 nerve root by coiling of the vertebral artery is reported; the diagnosis was confirmed by computed tomography (CT), magnetic resonance (MR) angiography and echocolordoppler. Although the enlargement of an intervertebral foramen by a tortuous vertebral artery has been described previously, the occurrence of radicular pain is exceptional. Magnetic resonance imaging (MRI), MR angiography and echocolordoppler allow to differentiate foraminal enlargement due to vascular anomalies of the vertebral artery from that more commonly due to tumor compression, mainly from neurinoma. Surgical decompression may be considered in symptomatic cases.

A 75-year-old man presented a twelve-day history of double vision and retro-ocular pain with rapid deterioration of visual acuity. Neurological examination on admission demonstrated right oculomotor palsy and abducence palsy, visual loss in the right eye, and hypesthesia and pain in the right supraorbital nerve. CT scan and MRI disclosed a mass in the right orbital apex. An emergency operation via a frontotemporal extradural approach was performed to decompress the optic nerve. The anterior clinoid process and minor wing of the sphenoid were drilled to expose the optic canal and superior orbital fissure. When the periorbita just beside the optic sheath was opened, a grayish colored mass was observed beneath the superior rectus muscle. The mass was dissected from the surrounding intraorbital tissue and was removed completely. The postoperative course was uneventful. The patient experienced complete disappearance of the ocular pain and complete restoration of his visual acuity. Orbital neurinoma is a benign tumor accounting for between 2.1 and 6.8% of all orbital tumors in the large series. The salient clinical symptom is exophthalmos followed by mass palpability. However, an orbital neurinoma presenting orbital apex syndrome is quite rare. In the case with orbital apex syndrome, it is sometimes impossible to recover visual acuity even though the optic nerve decompression is promptly performed. In such a case, only an emergency approach to the lesion can rescue the visual acuity.

The preoperative diagnosis of peripheral nerve schwannoma was correctly made by US in 3 patients referred to US because of upper extremity palpable mass. The patients complained of no pain and neurological symptoms, except in two cases where there was painful sensation radiating distally during lesion compression. In all cases, sonography demonstrated a sharply delineated hypoechoic homogenous mass with distal acoustic enhancement. The lesions were noted to be in a direct continuity with the cord-like echogenic structure consistent with a nerve. These features enabled a reliable diagnosis of peripheral nerve tumor, most likely schwannoma, to be made. Following a surgical excision, the diagnosis of schwannoma was confirmed by histopathology in all cases.
