Sonographic appearance of the torcular Herophili.

Sonographic demonstration of Galenic arteriovenous malformations in the neonate.

Cerebral arteriovenous malformation with aneurysmal dilatation of the vein of Galen often presents in the neonatal period with congestive heart failure. Five cases of galenic arteriovenous malformations diagnosed primarily by sonography are presented together with their angiographic and computed tomographic findings. A midline cystic structure posterior to the third ventricle with dilated strai...

A Case of Hypertrophy of Both Eyelids; Deficiency of Cranium over Torcular Herophili; Tumours over Both Eyebrows and Right Side of Face and over Trunk and Extremities

Total cerebral blood flow in the monkey measured by hydrogen clearance.

Total Cerebral Blood Flow in the Monkey Measured by Hydrogen Clearance • Simple hydrogen-sensitive polarographical electrodes of thin platinum wire were inserted into the torcular Herophili of Rhesus monkeys. Hydrogen was administered by inhalation for ten minutes, after which the hydrogen clearance was recorded from torcular blood. At a Paco, of 32 mm Hg (SD ± 2.3), flow in the fast flow compa...

Thrombosis of the torcular herophil

Results Six cases that were prenatally diagnosed by ultrasound between 22-28 weeks of gestation were reviewed. Four cases were further evaluated with fetal MRI. Associated findings included torcular and superior sagittal sinus dilatation in all cases and ventriculomegaly in two (33%) cases. Serial sonographic follow-up scans demonstrated a favorable antenatal course with complete resolution bef...
