Computerized tomography: abnormal intracerebral collections of blood in children.

Three children with unusual abnormal intracerebral collections of blood were examined by computerized tomography. These cases demonstrate the complementary relationship of this technique with other neuroradiological diagnostic methods. An intracerebral aneurysm and an arteriovenous malformation of the vein of Galen are demonstrated on computerized tomograms.

Slowing of hepatic blood flow by halothane: angiographic manifestations.

Extreme slowing of hepatic arterial flow occurred in 2 children who had angiographic examination under general anethesia with halothane. The incidence of this striking angiographic "halothane effect" was 32%. It was thought to be caused by a specific increase in hepatic vasomotor tone at the arterial, sinusoidal or venous level. The functional significance of the effect is unclear and its role in the production of hepatic dysfunction or massive hepatic necrosis is conjectural. No untoward effects were noted in our patients.

Early venous filling and controlled hyperventilation in cerebral angiography.

Controlled hyperventilation is a useful adjunct to angiography of tumours and inflammatory disease, giving increased demonstration of normal penetrating arteries and abnormal vessels. This shunting effect commonly causes early filling of the deep ependymal veins which should not be mistaken for early venous return due to tumour. While the effect could theoretically mask early venous flow secondary to tumour, this has not been our experience.

Computed tomography in infants and children: intracranial neoplasms.

Cranial CT proved exceptionally accurate in detecting and localizing cerebral neoplasms in children, with only one false negative case in 40 tumors. CT had its greatest diagnostic value in cerebral and cerebellar hemispheric lesions, tuberous sclerosis, and as a screening device for craniopharyngiomas. While CT may provide a definitive diagnosis, additional information form other neuroradiologic studies is often necessary.

Cranial computed tomography in infants and children.

Cranial computed tomography has been performed in adults for the past 2 years but relatively few children have undergone this procedure. The specific uses in children are in detecting intracranial mass lesions and identifying the character of the lesion, and evaluating congenital cranial diseases such as cerebral dysplasia, tuberous sclerosis and leukodystrophies. This safe, rapid, noninvasive technique will soon replace or supplement standard neuroradiologic techniques in infants and children.

The tethered conus.

The tethered conus is a real and treatable entity. It presents with a variable though fairly constant symptom complex. The diagnosis is probably not even considered in many patients with this condition. Recognition of the possibility of this condition by both the clinician and radiologist is needed. Properly performed oil or air myelography is the only method of preoperative confirmation of a tethered conus and should be done in all cases where it is suspected.
