[Peroperative echography in neurosurgery. Its value and applications 10 years later].

Intraoperative ultrasound imaging has many advantages over other imaging methods. The authors present their experience from hundred patients over ultrasound scanning. A large iconography is exposed. Not only the intracerebral lesions such as gliomas or metastases but also abscess or cysts can be controlled or biopsied directly. Per-operative ultrasonography is interesting for spinal cord lesions and spinal traumas. Ten years from the first utilisation in neurosurgery, the method is always used, its cost is low and its practice is very easy.

[Intramedullary neurinoma. Apropos of a case. Review of the literature].

The authors present a case of intramedullary neurinoma. A 44 years old patient was admitted for lumbar pain and bilateral sciatica. Neurological examination was normal except for dysuria and diminution of Achilles tendon reflexes. Lumbar spine X-rays and spinal cord angiogram were normal, but myelogram and myelo-scan revealed a fusiform enlargement of the conus medullaris. MRI confirmed this aspect. Total removal of an intramedullary tumor was done, using ultrasonography, operating microscope and ultrasonic aspiration. The post-operative course was uneventful, with, as sequelae a perineal hypoesthesia. Histological examination of the excised tumor revealed a neurinoma. The epidemiology, clinical features, radiology, and surgical treatment of such rare intramedullary tumors are discussed.

[Intervertebral biopolymer implant for arthrodesis. A study of 45 cases].

The B.O.P. biocopolymer is a bioresorbable, biocompatible product which can ossify. It has been used in 45 spinal arthrodesis, 42 times in cervical region but three in lumbar spine. The authors report their results after a follow-up period of 8 to 28 months. Persistent cervical pain has been noted in 9 cases. This was the most important postoperative complaint. Graft ossification has nevertheless been observed only in 40% of cases, as proved by simple X rays or/and scanner examination over a 26 months period. An osseous overproduction with posterior osteophytes could otherwise be observed. The authors remains cautious about using moreover this kind of graft, at least in its actual presentation, though the clinical results can be compared with these obtained with osseous autograft.

[Cauda equina syndrome complicating cutaneous T-cell lymphoma (mycosis fungoides)].

Authors present a case of a cutaneous T. cell lymphoma (mycosis fungoides) complicated by a cauda equina syndrome. Crural and sciatic radicular pain were due to epidural lumbar involvement by tumoral process. After surgical decompression completed by chemotherapy the evolution was uneventful. This case is the second one reported in the literature.

[Solitary plasmacytoma simulating pituitary adenoma].

A case of solitary plasmocytoma of the sphenoid is reported, masquerading as pituitary adenoma. At the time of surgery, the patient had no findings of multiple myeloma. The tumor was removed by trans-sphenoidal route and radiotherapy delivered. The post-operative course was uneventful, and two years later, there is no sign of recurrency or extension of multiple myeloma.

[Cervical chordoma. Apropos of a case].

The chordomas are malignant tumors arising from the remnants of the posterior spinal chord. The chordomas of the cervical spine are rare (5% of the spinal chordomas). A new case of spine chordoma at C5 level in a 76 years old woman is reported. The diagnosis depends on the results of the histological studies and especially the studies of the labelled elements as Protein S100 or Cytokeratin. Firstly a double osteosynthesis was realized by an anterior and posterior approach. There was no radiotherapy after this operation. A new operation for a fracture of odontoid process was necessary one year later. There was no recurrence. The patient was complaining from pains, two years after the first operation in relation to lateral recurrence. A third operation by an anterior approach was realized. A radiotherapy of 50 Gy was applied on the same level. The first osteosynthesis was with acrylic cement and the second one with an autologous bone graft and a plate after removing the cement without problem. Actually she is in good health, 78 years old.

[Rupture of neoplastic intracranial aneurysm caused by metastatic uterine choriocarcinoma].

Authors report a case of 18 years old woman with intracranial neoplastic aneurysm. Its rupture occurred one month after delivery, and the diagnosis of metastatic aneurysm from choriocarcinoma was made by pathologist. The craniotomy has allowed to remove the hematoma and the aneurysm with good immediate follow-up. In spite of X-ray-therapy and chemotherapy, the patient died one year after the outset from choriocarcinoma dissemination, in a comatose state. The review of the literature shows that this form of aneurysm is very exceptional. It is resulting from the invasion of the arterial wall by metastatic cells, by a neighbouring metastatic tumor or by another type of brain-tumor. In some cases, the aneurysmal rupture was the first symptom, before any gynecologic manifestation of the choriocarcinoma. The prognosis has been bad in such cases in spite of a commonly good response after chemotherapy.

[The injured cervical spine with and without lesions of the nerve structures. Clinical results of surgical therapy].

The operative treatment of the cervical spine injuries with and without neurological deficit was active developed in the last 25 years. The surgical management has been determined by the type of deformity, and also by the anatomical and functional specialties. The indication, the diagnostical and therapeutical strategy and the results of surgical treatment of 304 cases are discussed.

[Hand-Schüller-Christian disease with tumor localization in the posterior fossa].

A 19-year-old girl had been suffering since the age of 4 from Hand-Schüller-Christian disease. The condition was diagnosed by biopsy of a cranial bone lacuna. Later on, she developed diabetes insipidus and bilateral exophthalmos, both being typical signs of Hand-Schüller-Christian disease. At the age of 14, an intracranial tumour in the posterior cerebral fossa was discovered by computerized tomography, but in view of her parent's refusal of surgery, she was operated upon only 4 years later for obstructive hydrocephalus with intracranial hypertension. Two years after this operation, she presented with neurological signs of compression of the medulla oblongata, including tetraparesis and respiratory disorders, and the tumour was resected. Following a brief improvement she died of major hydroelectrolytic disorders due to her irreducible unstable diabetes insipidus. A review of the literature on Hand-Schüller-Christian disease and its rare association with intracranial tumours is analysed. The occurrence of such tumours raise important therapeutic problems and make the prognosis considerably worse.

[Primary cerebral lymphoma. Diagnostic and therapeutic values. Apropos of 4 cases].

The authors report four recent cases, of primary cerebral Lymphoma discovered since the use of the C.T. scan. Even though rare, the incidence of this tumor seems to be in slowly increase. The lesions on the C.T. scan are too variables and the surgical biopsy is necessary for the diagnosis. The primary cerebral Lymphoma should be considered more and more like the others Lymphomas. For this reason, they have started the treatment after surgical biopsy, with chemotherapy followed by radiotherapy associated with corticotherapy. The two last patients, are still alive with a follow up of 36 months for one of them. The prognosis seems to us, better as much as the diagnosis and the treatment was started early.
