A Review of Scandinavian Literature on Neuro-Radiology, 1939–1944

This excerpt was created in the absence of an abstract.

The Scandinavian countries have always been rich sources of contributions to the literature on neuro-radiology, and during the war years this high standard has been maintained.

Hemmingson, H., "Roentgenologic Investigation of the Intra-cranial Subdural Space with a View to Revealing the Presence of Subdural Adhesions", Acta Rad., 1940, xxi, 379.

A description is given of the anatomy of the subdural space and of the work of Penfield and Norcross on cerebral dural scars.

Using the Penfield technique of making a trephine hole and opening the dura with simultaneous removal of 60–80 c.c. of cerebro-spinal fluid by lumbar puncture, the author has examined the subdural space in cases of post-traumatic epilepsy and encephalopathy. He was able to demonstrate subdural adhesions in four cases out of eleven examined, and all four were verified at operation. The method may have an important bearing in the future, when, it is to be feared, the cranial injuries of war may present their indirect sequelæ. It is to be hoped that the author will report the post-operative results in these cases. The results of treatment of adhesions elsewhere in the body have in many cases been not too encouraging.

LINDGREN, E., "Roentgenological Views on Basilar Impression", Acta Rad., 1941, xxii, 297.

The radiological diagnosis of basilar impression is usually made on the lateral projection by the measurement of the basal angle as described by Schüller and others.
