An aneurysm of the vein of Galen can have a varied CT appearance in infancy. The classical picture is a spherical posterior third ventricular mass with the density of circulating blood contiguous with a dilated straight sinus and with uniform contrast enhancement. With varying degrees of thrombosis of the aneurysm which may occur in late infancy, the mass(More)
On the basis of myelographic findings, spinal adhesive arachnoiditis was classified into three types: type I (peripheral or marginal), type II (central), and type III (advanced). Depending on its location and extent, it may be divided into group A (lumbar), group B (thoracic), and group C (cervical). In view of the fact that intrathecal injection both of(More)
Computed tomography has proved to be the most effective mode of evaluating cerebral infarction in 143 documented cases. This was especially true when multiple focal infarcts were present. The incidence of contrast enhancement in acute infarcts was 88%. Concomitant acute and old infarcts were observed in 20% of cases. In the acute stage of stroke,(More)
Pituitary tumors commonly produce suprasellar extension. We have found that in assessing lateral suprasellar extent, the pneumoencephalogram and arteriogram are least accurate. CT scanning significantly increases the accuracy, and it is recommended that all patients with pituitary tumors have an initial CT scan.
