numbness of the left cheek had developed and vision in the right eye had begun to fail. An encephalogram made under intravenous anesthesia revealed a normal ventricular system, but a rounded mass was seen in the region of the sella turcica which had elevated the cisternae chiasmatica and interpeduncularis ( Fig. 2 ). The impression was that the patient had an atypical pituitary adenoma, an uncalcified craniopharyngioma or a teratoma of the pituitary region. Fig. 2. Air in the displaced cisternae chiasmatis and interpeduncularis outlines the superior surface of

Unusual Size and Extension of a Pituitary Adenoma

Case Report of a Chromophobe Tumour with Unusually Extensive Compression of the Base of the Brain, and Review of the Literature on the Pathways of Extension of These Tumours

James C. White and Shields Warren

* : This is caused by projection of the tumour directly upwards into the third ventricle behind a prefixed chiasm, as is so frequently the case with craniopharyngiomas. Here the usual symptoms, apart from visual disturbances, are headache and drowsiness, with possible evidence of injury to the autonomic centres. Jefferson points out that temperature variations and cardiac or respiratory alterations are not common with tumours that merely indent the hypothalamus without actually invading its walls, but polydipsia and polyuria may be produced by involvement of the

craniopharyngioma. Fig. 2. Lateral film, showing marked calcification in suprasellar region. The curved linear lines supposedly characteristic of an aneurysm are present. There is some demineralization of the sella, particularly noticeable in both the anterior and posterior clinoid processes. The latter are tilted forward and depressed. The floor of the sella is not distorted. Actually there is minimal change in the sella for a tumor of this type and size. Fig. 3. Posterior-anterior view, which shows the extensive character of the aneurysm. It measured 6

Children's Hospital, there have been 15 neoplasms of this group in 20 years. * With a series as large as the present one, it is possible to survey a considerable range of histological structure and of clinical behavior as well as to evaluate different forms of surgical management. Since certain tumors of the central nervous system have much histological resemblance to the group under discussion but present entirely different surgical problems, it has been necessary to set arbitrary limits to the series. Craniopharyngiomas and sacrococcygeal teratomas have been

diagnosis: probably craniopharyngioma. Operation . On Feb. 3, 1942 a right frontal craniotomy was performed. The dura was tense and 30–40 cc. of fluid were aspirated from the right lateral ventricle. This allowed retraction of the right frontal lobe and a good exposure of the chiasmal region. The reddish, bulging surface of an obvious tumor appeared between the optic nerves, this tumor having the gross appearance of a craniopharyngioma. The left optic nerve was pushed upward and outward. The right nerve was compressed to a lesser degree. The capsule of the growth was

The Torkildsen Procedure

A Report of 19 Cases

Edgar F. Fincher, Gordon J. Strewler and Homer S. Swanson

published 4 cases in 1946. The patients were all alive and well 6 months to 4 years after a Torkildsen procedure. The nature of the lesion in 3 cases was unknown but presumably involved the region of the aqueduct. In the 4th case an astrocytoma of the vermis was partially removed and a “prophylactic” tube installed. Rossier, 20 the Swiss surgeon, related an experience with a craniopharyngioma 1 in a 30-year-old woman who 2 months after the insertion of a Torkildsen tube was completely free from intracranial pressure and hemianopsia previously present. Palliation in this

T here continues to be justifiable pessimism among neurosurgeons as to the surgery of the craniopharyngiomas. This has been occasioned by the high operative mortality and the large number of cases in which total removal is manifestly impossible. It is the purpose of this paper to analyze the results in 51 consecutive cases of patients operated upon for craniopharyngioma at the University Hospital following the publication of Peet 7 in 1927 from the same source. The operation at this particular institution has invariably been approached with the object in
