Echo-encephalographic measurements (A-scan) of the lateral ventricles in children; its reliability.
A positioning of the probe on the skull has been developed to increase the diagnostic accuracy of hydrocephalus. Echo-encephalography in the trigonum region of the ventricles is usually possible in children up to 13 years of age. In this region sources of error as the medial wall of the temporal lobe or the lateral wall of the temporal horn are eliminated. In hydrocephalic ventricles the ultrasound measurements in this region corroborate very well with the measurements found in the pneumo-encephalograms. This in contrast to the measurements found with the probe placed in the more conventional region. As the largest diameter of the skull, corresponds with the trigonum region, a very practical topographic mark for a reliable standardized method has been found. With more confidence the ventricle indices of 93 normal children, in the age of 1 to 13 years, were measured.
