must be mentioned. This was Cushing's paper, 29 published in 1929 in collaboration with Louise Eisenhardt, on the tumors of this category arising from the tuberculum sellae. The importance of the contribution lies in calling attention to a diagnostic symptom-complex for a specific lesion so that a more intelligent operative attack could be planned. To use Cushing's own phraseology, Not only is it essential that the presence of a tumor and of its precise location be reasonably assured before it is attacked, but it should be possible to make at least a presumptive

A hyperostosis of the tuberculum sellae is apparent. B. ( A.

reflected toward the midline. The lateral ventricle is tapped to relieve pressure, following which the frontal lobe is retracted from the floor of the frontal fossa to expose the optic chiasm and perichiasmal region ( Fig. 1 ). The optic chiasm in hydrocephalus lies close to the tuberculum sellae. A thin arachnoid membrane stretches upward from the superior surface of the chiasm to the under surface of the frontal lobes. Immediately behind this membrane lies the cisterna chiasmatis, the posterior wall of which is the lamina terminalis. In typical cases of hydrocephalus

revealed an eburnation and thickening of the roof of the left orbit as far back as the tuberculum sellae, the lesser wing of the sphenoid, and the reflection of the greater wing of the sphenoid on the lateral cranial vault. The edges of the thickened bone were smooth and the increase in density homogeneous ( Figs. 5 and 6 ). These changes had resulted in a diminution in volume of the left orbit. Undoubtedly the skull changes long antedated the injury. Diagnosis: Sphenoid wing meningioma. Figs. 5 and 6. Case 3 . Thickening of roof of left orbit and of sphenoid

field in the other eye. Lateral roentgenograms of the skull suggested the presence of a tuberculum sellae meningioma. Right percutaneous carotid angiography was done using a total of 55 cc. of 35 per cent thorotrast. Within a few minutes it was evident that she had a motor aphasia and left motor and sensory hemiparesis with delusion of body scheme (anosognosia of Babinski). These symptoms were severe for about 30 minutes and then gradually receded over the succeeding 2 hours with complete recovery. At operation the tuberculum sellae meningioma was found to be

literature 53 cases of lateral ventricle meningioma. Including our 10 cases, we have been able to find no more than 70 cases of such tumors to date. But, it has become our impression that the lateral ventricle may be regarded as one of the most important seats of predilection for occurrence of meningiomas, on a par with the parasagittal region, the convexity, the sphenoidal ridge, the tuberculum sellae, the olfactory groove and the falx. SUMMARY Five cases of lateral ventricle meningioma verified at operation are reported with special reference to the angiographic

The tumor mass was of moderate size compared to the many years it had been growing, measuring in its AP diameter approximately 7 cm. inferiorly (along the floor of the middle fossa) to about 3 cm. or 3.5 cm. superiorly. Medially, it extended over the tuberculum sellae beneath the chiasm to the left of the midline. The lesser wing of the sphenoid and the orbital plate

. 3 and 4 ). This position is of importance in measuring the lateral displacement of these veins in the anteroposterior projection. When the head is rotated at the time the angiogram is exposed, stereoscopy aids in determining the presence or absence of lateral shift of these veins through the relationship of the internal cerebral vein to other fixed midline structures such as the superior and inferior sagittal sinuses, the tuberculum sellae and the crista galli. The internal cerebral vein, the anterior cerebral artery and the pineal body are considered midline

enlarged the optic foramen without extending intracranially. In the intracranial group the plain roentgenograms of the skull proved to be abnormal in all cases. In 4 of these patients the optic foramen was enlarged and in 2 the sella turcica was eroded. The characteristic deformity of the sella turcica associated with glioma of the optic pathway was first described by Martin and Cushing in 1923. 27 This is a pear-shaped configuration of the bony contour produced by erosion of the tuberculum sellae and the anterior clinoid process ( Fig. 7 ). In 3 patients both

hospitals. On the other hand, Horrax el al 5 have been reluctant to carry out such investigations in patients with definite clinical evidence of small adenomas impinging on the visual apparatus. However, all agree that pneumoencephalography or cerebral angiography is indicated if the symptoms are atypical and compatible with such diagnoses as craniopharyngioma, large aneurysm, meningioma of the tuberculum sellae or extrasellar extension of a pituitary adenoma. In order to rule out lesions simulating small pituitary adenomas, pneumoencephalograms were made on 6 of the 20
