The echogenic ependymal wall in intraventricular hemorrhage: sonographic-pathologic correlation.

Fifty-one patients with ultrasound diagnosis of intraventricular hemorrhage (Grades III and IV) were studied retrospectively for the presence of ependymal echogenicity. The sonographic findings were then correlated with histologic findings in six autopsy cases. Forty-one out of fifty-one newborns with intraventricular hemorrhage developed ependymal echogenicity on serial ultrasound studies. This echogenicity appeared approximately seven days after the hemorrhagic event and usually disappeared in about six weeks. Histologic examination revealed disruptions in the ependyma with proliferation and extension of subependymal glial cells onto the ventricular surface in those cases in which ependymal echogenicity was present at the time of death. This layer of proliferating subependymal glial cells may account for the ependymal echogenicity.

Closed spinal dysraphism: analysis of clinical, radiological, and surgical findings in 104 consecutive patients.

We reviewed 104 consecutive cases of closed dysraphism in patients seen at one institution between December 1984 and June 1987. All patients had myelographic studies, and 43 had associated CT examinations. Clinical and surgical findings (64 patients) were correlated with myelographic information. Twenty-three patients (22%) with clinical or plain film findings compatible with dysraphism had normal-appearing cords on conventional myelography, movement between supine and prone positions, and no lesions in the spinal canal. Cerebellar tonsillar ectopia (majority of tonsils between foramen magnum and C1) was found in 17 patients (16%). Six patients (6%) exhibited varying degrees of hydromyelia. In the supine position, CT-myelography of meningoceles, meningomyeloceles, or lipomeningomyeloceles may limit demonstration of the neural placode and nerve roots because of compression of the CSF-containing sac. In the decubitus position, CT scans improved demonstration of neural tissue-CSF space relationships. CT scans were useful in demonstrating anomalous paraspinal bones, diastematomyelia spurs, and spinal and sacral bone deficiency. Axial CT-myelography of intradural lipomas showed apparent neural tissue extension into the lipomas.

Computed tomography and spinal dysraphism: clinical and phantom studies.

Two cases illustrating the value of CT in the assessment of spinal dysraphic tissue are presented. In one case, the configuration and origins of two osseous diastematomyelic spurs were shown well; in the second case, the CT recognition of a sacral lipoma led to air myelographic confirmation of the tumor and tethered cord. CT phantom studies indicated that dysraphic tissues, such as fat, cartilage, and fibrous tissue, are better identified and quantitated in the spinal canal when surrounded by air. Varying degrees of image degradation occur with water (simulating CSF) or metrizamide.

Cerebral venous angioma: correlation of radionuclide brain scan, transmission computed tomography, and angiography.

Three cases of intracerebral venous angioma, a rare vascular malformation, were studied by radionuclide brain scan, transmission computed tomography (TCT) and angiography. In each case, the radionuclide flow study demonstrated a typical area of abnormal increase in activity during the venous phase; in two of the cases the arterial phase was also abnormal. Each contrast angiogram demonstrated a normal arterial distribution and a characteristic network of abnormal veins that converged to a large transcerebral draining vein. The TCT scans showed enhancing, curvilinear densities; while not specific, this finding should suggest the possibility of venous angioma in the brain.

Quantitative multiregional CSF kinetics using serial, metrizamide enhanced computed tomography.

Two rhesus monkeys studied by serial metrizamide (Amipaque) enhanced computer tomography (CT) imaging were used to quantitatively analyze cerebrospinal fluid (CSF) kinetics in multiple anatomical regions. Time--density curves were generated for the cisterna magna, suprasellar cistern, quadrigeminal cistern, and sylvian fissure, If clinical, biochemical, and routine static CT scanning indicate a profile suggesting normal pressure hydrocephalus, then CSF kinetics may be quantitatively and dynamically studied by CT imaging with metrizamide enhancement. This multiregional approach may be applied in an attempt to accurately distinguish normal pressure hydrocephalus from cerebral atrophy as a means of predicting which patients will likely profit from surgical diversionary shunting.

Claw hammer technique for extraction of knives.

A knife deeply imbedded in a patient's shoulder could not be pulled out easily before post-withdrawal angiographic study. The claw of a hammer was placed beneath the hilt of the knife for additional leverage, and the weapon was thereupon successfully removed. The advantage of a post-withdrawal angiogram to assess the degree of extravasation is stressed.

Transcatheter embolization of the spleen for control of splenic hemorrhage and in situ splenectomy: an experimental study using silicone spheres.

Silicone spheres were used for the transcatheter arterial embolization of dogs. This material successfully stops splenic hemorrhage in the lacerated organ, and also reduces spleen size. Use of silicone emboli to produce in situ splenectomy is not associated with morbidity or mortality in dogs. The authors discuss the value of using these methods in treating the high-surgical-risk patient.

131-I rose bengal liver scanning in the differential diagnosis of neonatal jaundice.

Results of a series of 2i liver scans with 131-I rose bengal in 21 patients who developed progressive jaundice in the neonatal period are described. Using the 131-I rose bengal scan alone, an attempt was made to separate the patients into two groups, the first with total bile obstruction (biliary atresia) and the second with only partial biliary tract obstruction (intrinsic liver disease). The diagnostic accuracy of the scan was 82%. An additional diagnostic criterion, the count radio, is suggested. The determination of this ratio requires no additional effort or expense and would improve the diagnostic accuracy of the scan used alone in this series of patients.

Incomplete, false, and true diastematomyelia: radiological evaluation by air myelography and tomography.

Six cases of possible diastematomyelia studied by air myelography with tomography were thought to involve fibrous or bony septa, but in each case no septum was found. Surgical findings included prominent midline posterior fissures in the cord associated with fibrous bands, an unusual tentlike extension of the arachnoid over the spinal cord, and hemicords with no intervening septum. Recognition of an osseous septum on the plain film does not necessarily mean that the cord is completely divided by bone, as other structures derived from the mesoderm, such as fat or cartilage, may contribute to the septum. The importance of defining tethering of the cord posteriorly at the septum or conus level is stressed. Air myelography with appropriate projections appears to show posterior fixation of the cord to best advantage.

The "starry night" splenic angiogram. Contrast material opacification of the malpighian body marginal sinus circulation in spleen trauma.

In traumatized human spleens, focal 0.3-1 cm. areas of contrast material staining appear to represent the malpighian marginal sinus circulation. This circulation, when seen, is static or very slow moving. Extravasation of blood and contrast material also may be present in the marginal sinus network. The identification of diffuse or localized small areas of contrast material in the splenic angiogram of the traumatized patient suggests splenic contusion, intrasplenic hematoma, or both. The splenic angiographic appearance described may be compared to the globular appearance of stars, as depicted by van Gogh in his painting "The Starry Night."
