Diffuse neonatal hemangiomatosis.

Diffuse neonatal hemangiomatosis is an often fatal disorder characterized by widespread capillary hemangiomas of the skin and visceral organs. Ultrasound and computed tomographic scans may be useful in determining the extent of visceral disease. The organs most commonly affected are the gastrointestinal tract, brain, liver, and lung. Complications include high-output cardiac failure, gastrointestinal bleeding, hydrocephalus, and consumption coagulopathy. Despite therapy with corticosteroids, the mortality rate is high.

Left ventricular outflow obstruction produced by a pedunculated fibroma in a newborn: clinical, angiographic, echocardiographic and surgical observations.

An unusual case of a one-day-old infant with significant left ventricular outflow obstruction produced by a pedunculated fibroma is described. The clinical findings were indistinguishable from severe valvular or subvalvular aortic stenosis. The tumor was difficult to detect by echocardiography. It produced an echo-free widening of the left ventricular outflow tract. Left ventricular cineangiography clearly demonstrated a mobile mass beneath the aortic valve.

CT detection and course of intracranial hemorrhage in premature infants.

Twenty neonates with a suspected intracranial hemorrhage were studied by computed tomography (CT). The exact site and extent of the hemorrhage in all infants were clearly demonstrated on serial CT scans. In intraventricular hemorrhage, a dense subependymal halo lined the ventricular system and could be recognized for up to 2 weeks. Discrete hemorrhage adjacent to the ventricular system also appeared as discrete nodules rather than as a diffuse hemorrhage. Blood in the ventricular system could be recognized up to 2 weeks when there were blood-cerebrospinal fluid levels. Hydrocephalus was a common sequela and was readily detectable before a measurable change in head size.
