[Isolated idiopathic amyloid tumor of the sacrum. An important differential diagnosis].

Primary amyloidosis may present as a pseudotumoral mass. Often associated with myeloma or paraproteinemia, it may also be isolated, without preexisting or associated disease. Isolated pseudotumoral bone involvement is rare and especially in the spine. Differential diagnosis is very important, because the prognosis of primary amyloidoma is excellent after surgical removal.

Unusual occurrence of a pseudo-aneurysm of the middle cerebral artery in a patient with fibromuscular dysplasia.

Our patient is the first reported case of pseudo-aneurysm due to the rupture of an intracranial artery in the context of fibromuscular dysplasia (FMD). As we assume that our case is probably not unique, we conclude that this diagnosis may be sometimes overlooked for lack of confirmation either by surgery or autopsy. The retrospective study of the arteriograms suggests some clues that should be taken into account to foresee the existence of an intracranial pseudo-aneurysm in order to avoid unexpected peroperative difficulties: 1.) the rapid growth of the lesion within a few weeks and 2.) the unusual location of the aneurysmal neck at some distance from a arterial bifurcation.

Gram-negative bacillary meningitis in neurosurgical patients.

The authors report 34 cases of Gram-negative bacillary meningitis related to traumatic cranial lesions or neurosurgery observed between 1973 and 1980 at two neurosurgical units (Institut J. Bordet, Brussels, and Inselspital, Bern). As a typical nosocomial infection, meningitis developed after prolonged hospitalization in most patients, and was mainly due to highly resistant organisms, such as P. aeruginosa and Klebsiella sp. At least 65% of the patients were colonized with the pathogen responsible for the meningitis before the onset of the infection. Ventriculitis, including four cases of ventricular empyema, complicated meningitis in all the 17 patients in whom a ventricular tap was performed. The results of treatment were unsatisfactory. Fifty percent of the patients were cured of their infection, but only 30% survived; 15% of the patients died within 48 hours following diagnosis. The optimum treatment of postsurgical Gram-negative meningitis remains in doubt. The choice of initial antibiotics should take into account the sensitivity patterns of colonizing microorganisms. Chloramphenicol is ineffective against most pathogens commonly involved in this infection. Intrathecal aminoglycosides may fail in the presence of ventriculitis. Intraventricular aminoglycosides are probably justified in critically ill patients. The role of the newer cephalosporins and of co-trimoxazole remains to be defined.

[Normotensive hydrocephalus. Retrospective clinical study of 47 cases].

The clinical observation of 47 patients, undergoing surgery for "normotensive hydrocephalus" during the period January 1975 to January 1981 have been analysed retrospectively. The condition of half the patients improved following insertion of a cerebrospinal fluid bypass. Complications of varying degrees of severity were noted in 21 percent of cases. The correlation between the post-operative results and the clinical data was subjected to statistical analysis. Some factors appeared to have an important predictive value. These were the age, the absence of cortical atrophy on C.T. scan and the prolonged ventricular filling on cisternography. Other factors, although without statistical significance, seem to predict a better result: the existence of prior etiological data, presence of a frontal syndrome and evidence of periventricular hypodensity on C.T. scan. Finally, some other factors in our series appeared to have no influence on the prognosis. These were: duration of the preoperative evolution of the disorder, the degree of mental disturbance and difficulties of gait, the presence of urinary incontinence, the value of the ventricular cranial ratio. None of the recognized significant criteria was sufficiently reliable to predict the quality of surgical result, when studied in isolation. The association between the different significant criteria, such as have been described above notably, improves the chances of a favorable post-operative outcome but it is insufficient to predict it with great certitude. The continuous monitoring of the intracranial pressure during periods of 24 to 48 hours appears to be the most reliable factor on which to make a decision to operate in the light of the findings described in recent literature.

Effects of 1% and 2% enflurane on intracranial pressure in man.

We have studied the effects of enflurane on intracranial pressure (ICP) in 9 neurosurgical patients, whose ICP was continuously monitored for therapeutic or diagnostic purposes. The control ICP was under 15 Torr in 5 cases, under 20 Torr in 3 cases and of 25 Torr in one case. In order to achieve stable ventilatory conditions, the patients were kept under controlled ventilation, breathing a mixture of 60 to 70% nitrous oxide and oxygen. The PaCO2 was kept constant, at the pre-study level. Mean arterial pressure (MAP) was maintained stable with the administration of fluids and/or a phenylephrine drip. Cerebral perfusion pressure (CPP) was calculated as the difference between MAP and mean ICP. After a control stabilization period of about one hour, enflurane was introduced in the circuit at successive concentrations of 1 and 2% during 20 to 30 minutes. In seven patients, enflurane did not produce any change of ICP. ICP rose only in 2 patients, whose control values were of 16 and 25 Torr. The overall changes, however, are not significant. There is a small significant decrease of MAP and CPP under 2% enflurane when compared to control, of probably no clinical importance (under 10% change). Our results do not show that enflurane is entirely without effect on ICP, but we think that 1 to 2% enflurane may be used in neuroanesthesia with a reasonable margin of safety, in association with slight hyperventilation and other means or reducing ICP, in accordance to clinical requirements.

[Solitary vertebral osteochondroma with spinal cord compression (author's transl)].

Solitary vertebral osteochondromas with spinal cord compression are very rare. Here we report a case of an osteochondroma of the 5th cervical vertebra protruding into the spinal canal. The therapeutic approach is discussed in relation to the natural evolution and the favourable prognosis of these lesions. The usefullness of the C.T. scan is shown both in diagnosis and post-operative follow-up.

[Epidural metastases at the spinal level. Clinical study of 82 cases].

This is a retrospective review of 82 cases of spinal epidural metastasis. A warning vertebral or radicular pain was present in 85% of the cases. In 33% of the patients, who complained only of pain without any neurological deficit, a complete myelographic block was already present. It is thus of prime importance not to neglect a vertebro-radicular pain in cancer patients, and even in patients without known cancer since the epidural metastasis was the first manifestation of the neoplasm in 30% of our cases. The indications for myelography are defined. The functional result (i.e. ability to walk) after treatment depends on the neurological state before treatment. In our series, total paraplegia was always irreversible. Early diagnosis and treatment are thus very important. The surgical treatment alone is judged insufficient. We were not able to prove the superiority of one of the following therapeutic modalities: laminectomy followed by radiotherapy or radiotherapy alone. Radiotherapy is indicated in all cases, often as the sole treatment. The indications for surgery are defined; they are based on our own experience and the literature. High dose steroids are indicated as adjuvant therapy.

[The surgery of peripheral nerves. New perspectives in treatment by the microsurgical techniques (author's transl)].

The author describes the different techniques of reconstructive surgery of peripheral nerves and the failures that marked these trials until the advent of microsurgical techniques. After stressing the importance of the biology and physiopathology of a traumatized nerve and its stem cells, the author detailes the regeneration stages of the nerve cell when ideal conditions of axonal alignment are established by microtechniques. Considering the different notions of biology and pathology in relation to the time delay between the traumatism and referral to the surgeon, the author insists on the absolute necessity of operating during the period of full regeneration of the nerve cell, i.e. within the first 6 months.

Non traumatic cerebellar hematomas.

Five cases of spontaneous cerebellar hematomas are reported. In four cases the diagnosis was made by computerized tomography. The clinical diagnosis being difficult, surgical treatment was often applied too late and the diagnosis sometimes never made. Systematic use of computerized tomography should allow earlier treatment of this type of lesion, the clinical evolution determining the prognosis. (Acta neurol. bels., 1980, 80, 73-79).
