Twenty-four patients of comparable age, blood pressure, and degree of dementia were classified by an "Ischemic Score" based on clinical features into "multi-infarct" and "primary degenerative" dementia. Regional cerebral blood flow (CBF) was measured by the intracarotid xenon 133 method. Both groups showed a decreased proportion of rapidly clearing brain(More)
Twenty-eight patients with aneurysms of the posterior circulation were managed by direct operations, 53.6% of these being done within 14 days of a subarachnoid hemorrhage. Transvenous cardiac pacing was used in 4 of the 13 patients with aneurysms of the basilar bifurcation in order to produce a short period of profound hypotension while final dissection and(More)
We report the radiological appearances of 5 children with hemimegalencephaly. There are few reports of this rare condition in the radiological literature. Two of the children have hemimegalencephaly as an isolated finding while the other three have Proteus syndrome. Four children have seizures which commenced within the first 6 months of life and two of(More)
BACKGROUND Twenty per cent of patients with bipolar affective disorder suffer an illness that responds inadequately to treatment and has a poor outcome. Many patients, but not all, with bipolar disorder show white matter abnormalities on T(2)-weighted magnetic resonance imaging (MRI). AIMS To explore the hypothesis that white matter abnormalities on MRI(More)
OBJECTIVE It is established that patients with bipolar disorder have an excess of births in winter or early spring. The authors investigated a link between season of birth and white matter lesions with magnetic resonance imaging (MRI). METHOD T(2)-weighted and proton density MRI scans were examined for 79 patients with bipolar disorder (DSM-IV) for the(More)
Eight cases of vertebral haemangioma causing spinal cord or nerve root compression are described, together with one other which was not causing organic signs or symptoms. The compression was due to extradural tumour in 5 cases, bony expansion encroaching on the neural canal in 2 cases, and a combination of bony expansion and extradural tumour in one case.(More)
The radiological appearances of the trigeminal cistern on metrizamide cisternography and metrizamide CT cisternography are described. The frequent demonstration of this cistern on metrizamide cisternography is emphasised. A case of nontraumatic CSF rhinorrhoea produced by a CSF leak between the trigeminal cistern and the sphenoid sinus is described.
A series of 38 cases of colloid cyst of the 3rd ventricle is described in most of whom the diagnosis, important for curative surgery, was made radiologically. The most useful investigative technique was pneumography, by which the tumour was outlined in almost all cases. The lateral "hanging head" projection generally demonstrated the lesion most(More)
The authors have reviewed 167 cases of subarachnoid hemorrhage (SAH) occurring in patients aged 20 years and younger in a 23-year period. The modes of presentation and etiology of SAH are similar in childhood and adolescence and in the adult population, but there was a different incidence of the specific pathology producing the bleeding in this series.(More)
Temporal lobe and limbic structures may be abnormal in bipolar disorder. T2-weighted magnetic resonance imaging (MRI) scans frequently show deep white matter lesions. MRI was performed on 50 young (19-39 years) euthymic patients with bipolar disorder and 26 controls. Mean temporal lobe volumes were reduced in patients (right, 9.42 cm3; left, 6.33 cm3) but(More)
