A retrospective case note survey of chronic subdural haematomata was carried out in an attempt to throw some light on the difficulties encountered in clinical diagnosis. The combination of raised intracranial pressure headache, fluctuating drowsiness and mild hemiparesis, although highly suggestive of subdural haematoma, is not always encountered, and epilepsy, aphasia, hemianopia and dense hemiplegia can all occur contrary to 'text book' descriptions. Head injury or other aetiological factors are commonly absent. The presentation may mimic tumour, dementia, cerebrovascular accident or subarachnoid haemorrhage. Non-invasive investigations may yield false negative results, although in the case of radionucleide scanning and computerized axial tomography the reliability is approaching 90 per cent. The diagnosis will, however, remain an unexpected finding at angiography in a percentage of cases.

We describe 3 children with a progressive encephalopathy that was characterised by irritability, convulsions, cranial nerve palsies, ataxia, nystagmus, walking difficulties, delayed psychomotor development, hemiplegia/tetraplegia, visual disturbance, vomiting, neck stiffness, and non-specific signs of raised intracranial pressure. A final diagnosis was made in all 3 patients from necropsy material. The clinical features were ascribed to multiple inflammatory, predominantly lymphocytic, reactions and raised intracranial pressure. This condition is an atypical form of haemophagocytic lymphohistiocytosis, which normally presents with fever, hepatosplenomegaly, and cytopenias. By contrast, the disease pattern in our 3 children was dominated by cerebromeningeal involvement, which can precede the typical systemic symptoms of haemophagocytic lymphohistiocytosis. An awareness of this condition is important because treatments are available.

Long-term extracranial shunting for hydrocephalus has numerous drawbacks related to shunt malfunction and infection. In some cases outcome has been very disappointing. We successfully managed 5 patients with acquired aqueductal stenoses with no significant morbidity by the use of an intracranial cerebrospinal fluid diversion, namely a third ventriculostomy. First advocated by Dandy, ventriculostomy was largely passed over in favor of extracranial procedures. With improved surgical techniques, however, ventriculostomy is now considered to be a viable alternative in selected cases. In a further 19 patients, we subsequently broadened our patient selection to include those with Arnold-Chiari malformations, congenital noncommunicating hydrocephalus, and tumors. Two thirds of these children remain without shunts and apart from 1 child developing hemiplegia postoperatively, there has been no significant morbidity. Although the best results have been seen in the late onset groups, even early onset, noncommunicating hydrocephalus has been successfully managed. Even in patients in whom third ventriculostomy has failed and who have subsequently required ventriculoperitoneal shunts, we anticipate that they will remain less dependent on shunts because their hydrocephalus is now communicating, which tends not to have such a rapid onset or extreme levels of raised intracranial pressure.

In congenital porencephalies, diverticulation of the lateral ventricle is a dynamic process producing compression and stretching of the brain tissue bordering the diverticulum, bulging of the overlying skull, macrocephaly, and occasionally progessive neurologic signs (hemiplegia, raised intracranial pressure), even when the rest of the ventricular system is not dilated and the CSF pressure is normal. Ventriculoperitoneal shunting can result in remarkable improvement of focal motor deficits and may apparently also play a beneficial role on further mental development. Successive computed tomography scans demonstrate that the brain parenchyma, which had been stretched by the porencephalic pouch, is capable of regaining near normal thickness. Congenital porencephalies are initiated by a limited destructive brain lesion, but the gradual expansion of the ventricular herniation may imply a mechanism identical to that which has been postulated in normal pressure hydrocephalus. Nine cases of unilateral "expanding" congenital porencephalies are presented and the treatment of this condition is discussed.

Intracranial metastases of central nervous system are relatively common in patients with systemic cancer. Computed tomography (CT) scans of 60 patients of intracranial metastatic disease of unknown primaries, at the time of surgery, were retrospectively analyzed. These patients primarily presented with neurological dysfunction. They were operated upon for various reasons and histopathological diagnosis was obtained. There were 39 male and 21 female patients, with age range of 18 to 74 years. The common clinical symptoms were raised intracranial pressure without lateralization, acute onset hemiplegia and seizures. Multiple cranial nerve palsies were observed in 4 patients. Histopathologically the intracranial lesions consisted of metastatic adenocarcinoma (32 cases) or metastatic squamous cell carcinoma (28 cases). Among cases of adenocarcinoma, CT revealed solitary lesions in 17 and multiple lesions in 13 cases. Two had extraaxial deposition in the region of petrous apex. Out of squamous cell carcinomas, 17 lesions were solitary, while 10 were multiple and one had extraaxial deposition in the region of petrous apex. This study is unique as it consisted of CT features of intracranial metastases of unknown primary malignant disease elsewhere in the body.

Mycoplasma pneumoniae (M. pn.) commonly causes respiratory tract infections in humans. In a certain percentage of cases it may also be associated with various peripheral and central nervous system manifestations. We report a case of a 38-year-old previously healthy man who presented with hemiplegia and somnolence after he had suffered from a febrile respiratory infection 10 days earlier. Clinical features and laboratory investigations supported the diagnosis of an acute M. pneumoniae-associated meningoencephalitis. He was treated by an aggressive antibiotic and immunomodulatory regimen over the course of several weeks in the neurocritical care unit. Decompressive hemicraniectomy was performed due to life-threatening raised intracranial pressure. However, the patient recovered almost completely and presented with a mild neurological deficit after 3 months. Based on this case we give a review of the literature and discuss potential pathomechanisms and diagnostic approaches.

Raised intracranial tension affects the course of tuberculous meningitis adversely. The development of hydrocephalus may account for the raised intracranial pressure. Insertion of a ventriculoatrial shunt significantly alters the course of the disease. The results in seven cases have been detailed and discussed. The levels of consciousness improved, hemiplegia and aphasia practically cleared up, and vision returned even in children who were blind for 4 to 6 weeks. Operation could be performed even in an active stage of the disease without much fear of miliary dissemination.

High-altitude cerebral oedema (HACO) is the most fatal high-altitude illness seen by rural physicians practising in high-altitude areas. HACO presents clinically with cerebellar ataxia, features of raised intracranial pressure (ICP) and coma. Early identification is important as delay in diagnosis can be fatal. We present two cases of HACO presenting with focal deficits mimicking stroke. The first patient presented with left-sided hemiplegia associated with the rapid deterioration in the sensorium. Neuroimaging revealed features suggestive of vasogenic oedema. The second patient presented with monoplegia of the lower limb. Neuroimaging revealed perfusion deficit in anterior cerebral artery territory. Both patients were managed with dexamethasone and they improved dramatically. Clinical picture and neuroimaging closely resembled acute ischaemic stroke in both cases. Thrombolysis in these patients would have been disastrous. Recent travel to high altitude, young age, absence of atherosclerotic risk factors and features of raised ICP concomitantly directed the diagnosis to HACO.
