摘要:

From autopsy and neuroradiological studies a maximum prevalence of unruptured intracranial aneurysms (UA) of 0.5% in the general population is revealed. Studies concerning the incidence of aneurysmal subarachnoid haemorrhage (SAH) revealed 10 cases per 100,000 inhabitants per year. From these epidemiological parameters a minimum annual risk of 2% of rupture of an UA is calculated. It is in accordance with clinical studies, which also demonstrated an annual risk of UA rupture of at least 2%. No critical size of the UA predisposing to rupture has been found. Operation on diagnosed UA is recommended because of the serious prognosis after aneurysmal SAH (morbidity 20%-25% and mortality 50%-60%) and because the morbidity (4%) and the mortality (0%) after operative treatment of UA are very low.

摘要:

A theoretical evaluation of the lifetime probabilities of different outcomes in patients with unruptured intracranial aneurysms (UA) has been made using a life table method. The calculations were performed for aneurysm presenting ages from 20 to 70 years of age for men and women assuming an annual risk of aneurysm rupture of 1 %, 2% and 3% and a rate of mortality after rupture of 50%. At 10, 20, 30, 40, 50 and 60 years after the diagnosis of an UA the probability of survival without bleeing is reduced below the expected probability of survival according to the life tables by the following percentages (assuming an annual risk of bleeding of 2%): 19%, 34%, 46%, 56%, 64% and 72%, respectively. A survey of the lifetime probabilities of four different outcomes for patients with an UA indicates a substantial reduction in life expectancy after the diagnosis of an UA. In most ages the surgical risks are more than balanced by the risks associated with an untreated unruptured aneurysm

摘要:

We describe two patients with neurofibromatosis, each of whom was found to have an arteriovenous malformation (AVM), an uncommon manifestation of the disease, presenting as an extradural space-occupying lesion in the cervical spine. In one patient the finding of an unsuspected AVM at operation led to massive blood loss; in the other magnetic resonance imaging (MRI) of the neck allowed the diagnosis to be made and the hazard of an operation to be avoided. Solid tumours that may occur in the disease of neurofibromatosis are known to cause neurological deficits as the result of space occupation. We wish to draw attention to another pathological entity which may cause neurological deficits: that of AVMs. We also propose that in the investigation of such a patient MRI be borne in mind as a non-invasive radiological tool, particularly as, hopefully, its cost reduces and its availability becomes more widespread.

摘要:

CSF shunt malfunction is nowadays a common emergency. It may occasionally simulate some more sinister underlying central nervous system disease. We describe three examples where simple mechanical revision of a faulty shunt reversed bizarre and misleading neurological syndromes.

摘要:

An opera singer, who“made her living with her diaphragm”, developed a post-traumatic unilateral radiculopathy due to cervical disc lesions, C3 to C6. During one year of severe neck and left arm pain she gradually lost the ability to sing difficult operatic passages which brought an end to her music career. Following a three level anterior cervical decompression and fusion, the neck and arm pain was immediately relieved. One week later her voice and singing ability returned to its full strength and power permitting her to resume her activities as a vocalist. The diagnosis of paresis of the left hemi-diaphragm as part of the cervical disc syndrome was implied by postoperative retrospective inference.

摘要:

Lymphocytic adenohypophysitis is a rare auto-immune disease usually bearing a temporal relationship to pregnancy. We report a 37-year-old woman with this condition, who presented with bitemporal hemianopia in the postpartum period. She represents the mildest expression of the disease entity yet described, and showed spontaneous tumour regression.

摘要:

A case of transsphenoidal meningohydroencephalocoele is presented. The clinical features and pathogenic factors are discussed briefly. An awareness of this condition should prevent attempted biopsy—which might otherwise prove disasterous. Air or contrast cisternography, with plain or computerised tomographic radiology, would seem to be the investigation of choice.

摘要:

Tumours related to intracranial aneurysms are rare. The authors report the metastasis of a parotid acinic cell carcinoma which spread to an intracavernous carotid aneurysm in a 51-year-old female. The tumour and aneurysm were partially excised at craniotomy with relief of the patients presenting headache.

摘要:

Diffuse cerebrospinal gliomatosis is extremely rare. We report the case of a 47-year-old man who presented with clinical features of intracranial hypertension. He developed ascending paraplegia and died. This latter clinical feature has not previously been reported. Clinical features and diagnostic difficulties are discussed.
