Seven children with rapid enlargement of the head and other clinical features resembling hydrocephalus are described. All children remained with relatively large heads, developed slowly and all but one had various degrees of mental and motor handicaps. The EEG was disturbed in all cases; two children developed seizures. Increased intracranial pressure was present. In all patients the subarachnoid space was markedly widened while the ventricular system was normal or minimally dilated. The characteristics of this syndrome, the features distinguishing it from similar conditions as well as its possible mechanism are discussed.

Twenty cases of cysticerosis involving the central nervous system were seen during a 6-year period. Twelve patients presented with symptom and signs of raised intracranial pressure, 6 with seizures and 1 each with subacute meningitis and psychosis. The diagnosis of cerebral cysticercosis was established by brain biopsy in 8 patients, at autopsy in 3, and by biopsy of a subcutaneous nodule in 7. It was presumed on the basis of typical intracranial calcification in 1 case and soft tissue calcification in another. The protean clinical manifestations of this condition and the diagnostic difficulties it raises are discussed.

The authors report a boy aged 9 years in whom a giant meningioma of the small wing of the sphenoidal bone was removed surgically. Attention is called to the rarity of these tumours in the first decade of life. Developmental retardation, speech beginning at the age of 4 years, large head and epileptic seizures developing at the age of 7 years without signs of intracranial hypertension suggested the possibility of organic brain disease and development of massive hemiparesis, speech disturbances and choked disc in the last period of the disease were the cause of referral of the child to a neurosurgical unit. Plain skull films and angiography demonstrated changes typical of raised intracranial pressure and presence of an expanding lesion in the left cerebral hemisphere. Meningioma was found on operation hidden within the left frontal and temporal lobes but connected by means of a narrow band to the dura of the small wing of the sphenoidal bone. A good result was obtained. Follow-up examination after 2 years demonstrated slight neurological abnormalities and a very good general state of the child.

Two hundred and thirty-four cerebrospinal fluid (CSF) specimens from 183 different children were analysed for total lactate dehydrogenase (LD) activity and LD isoenzyme distribution. The LD activities were elevated in the CSF of patients with meningitis, especially with bacterial infections, and with central nervous system (CNS) leukaemia. The CSF LD isoenzyme patterns of both groups generally reflected the number and distribution of lymphocytes and granulocytes in the CSF. Increases in CSF LD levels also occurred in patients with other neurological disorders, such as hydrocephalus, raised intracranial pressure, and epileptic seizures. However, no significant increases in CSF LD activity nor abnormality of the isoenzyme distribution were noted in children who had had a non-specific febrile convulsion.

Neurocysticercosis was diagnosed in 0.89% of children enrolled in our Child Neurology Clinic in the years 1979 to 1990. The commonest presenting symptom was seizures (90%) followed by raised intracranial pressure (44%). CT scans revealed a variety of lesions including low and high attenuation cysts, periventricular edema, hydrocephalus and calcification. ELISA was useful in substantiating the diagnosis in almost 70% of cases. Only 18 patients who had active disease merited treatment with praziquantel. The clinical and CT response was good. Follow-up revealed spontaneous quiescence in many patients with inactive disease.

We report two cases of Langerhans' cell histiocytosis with unusual central nervous system (CNS) involvement. The first patient had behavioural disturbances, memory loss and diabetes insipidus. His response to a range of treatments was poor. The second patient presented with seizures and headaches suggestive of raised intracranial pressure. Etoposide (VP16) chemotherapy led to a dramatic clinical and radiological improvement. The various CNS manifestations of Langerhans' cell histiocytosis and their management are discussed.

Intraventricular neurocytoma (IN), a recently recognized, benign cerebral tumor of young adults, can be confused with oligodendroglioma and other neoplasms. The authors compared the radiologic features of six pathologically confirmed cases of IN with those of 26 previously reported cases. The presenting symptoms were headache (62%), raised intracranial pressure (41%), and seizures (12%). Radiologically, the tumor frequently demonstrated a characteristic attachment to the septum pellicidum and confinement to the lateral and third ventricles. Calcification, which is common in IN and an important diagnostic feature, was seen to best advantage on computed tomographic (CT) scans. The results indicate that IN can be suggested radiologically on the basis of its CT appearance and should be included in the pathologic differential diagnosis of intraventricular tumors.

Despite the introduction of a number of new injectable agents, ultrashort barbiturates continue to be popular. Some of the reasons include rapid, smooth onset of action; predictable hypnotic effects; relatively rapid, smooth recovery; and inexpensiveness. Ultrashort barbiturates also possess some pharmacodynamic properties that make them ideal agents for use in patients with certain diseases or undergoing certain procedures. These include patients with raised intracranial pressure, patients with a history of seizures, patients with corneal lacerations or glaucoma, patients for examination of vocal cord and arytenoid cartilage function, patients with hyperthyroidism, and patients thought to be susceptible to malignant hyperthermia.

Increased intracranial pressure is present in more than 80% of patients with fulminant hepatic failure. However, patients with encephalopathy secondary to chronic liver disease are thought not to develop elevated intracranial pressure. We report two patients with chronic liver disease in hepatic coma with raised intracranial pressure documented by an epidural intracranial pressure monitor. One patient rapidly deteriorated to coma over a period of 4 h. The other patient progressively worsened following intravenous sedation administered during upper endoscopy. Both patients had generalized tonic-clonic seizures, and one demonstrated decerebrate posturing and papilledema. Although all metabolic and structural abnormalities should be excluded in patients with hepatic encephalopathy, if the etiology remains in question, the possibility of increased intracranial pressure should be considered in patients with chronic liver disease.

Tuberculomas of the brain are relatively uncommon in developed countries nowadays. We report the only two cases that were seen in our Department in the last five years. Both patients presented with seizures and were found to have space occupying lesions on cranial CT scanning. They had no past history of tuberculosis, no evidence of current extracranial tuberculosis and the diagnosis of tuberculoma was made at the time of surgical excision. Underdiagnosis of tuberculoma of the brain is likely to occur in industrialised countries where tuberculosis is rare. The radiological investigation of choice is CT scanning with contrast enhancement and the presence of a target lesion is considered to be pathognomonic of a tuberculoma. Most tuberculomas of the brain can be treated medically with antituberculous chemotherapy. We recommended obtaining a definitive histological diagnosis with CT-guided stereotactic techniques prior to commencing antituberculous therapy. Surgical excision is necessary in patients with raised intracranial pressure secondary to the lesion and not responding to medical therapy.
