other operative complications. Again in 1910, 15 Cushing reported upon his last 100 patients with brain tumor, saying, that in 30 instances there had been tumor extirpations or cyst evacuations with apparent cures, and 67 palliative procedures. There were only 11 deaths and none of the “oldtime postoperative complications.” These figures may not sound very optimistic now, but it must be recalled that the most eminent neurologists of those days (Starr, Knapp and Mills in this country, and others abroad) had estimated from collected operative and postmortem material

A more detailed example of the use of foam is given in the following case history: K.G. CH #238090. A well developed and nourished 12 year old school girl was admitted with complaint of headache and vomiting. Four years previously she had had an incomplete removal of a cystic astrocytoma of the right cerebellar hemisphere. Physical examination showed high grade papilledema, ataxia; in short

-months pregnant, an ovarian cyst was removed. She has one child, a boy of 13. Personality . She has always been a sensitive, seclusive and worrisome individual. Throughout childhood and adolescence she worried over her family's financial status, over school grades, and many other matters without adequate cause. Present Illness . In September 1939 the patient began to express ideas of reference and self-condemnation. Her husband was experiencing financial reverses and the patient suspected that people were conspiring against them. She blamed herself for every misfortune to

I n the course of certain experiments on the rabbit's brain we have performed a standard decompressive operation in about 270 animals (Russell and Falconer, 1941; 2 Falconer, McFarlan and Russell, 1943 1 ). Apart from the main results in these experiments we have noticed, as an apparently independent side-issue, certain pathological changes in the subcortical white matter beneath the centre of the site of operation in about 50 per cent. of the animals, with the formation of a cavity or cyst in about 30 per cent. These changes appear to be intimately

Intracranial Dural Cyst

With Report of a Case

C ysts located solely within the dura mater are a rarity. Apparently the only one on record was situated in the spinal canal. The case in point, described by Voss, 9 concerned a boy aged sixteen who over a period of about three months had developed symptoms of compression of the lower thoracic cord. Myelography disclosed subarachnoid block at the levels of the fifth and the eighth thoracic vertebrae. There was also a uniform dilatation of the spinal canal in this region. At operation a non-pulsating, pale cystic structure extending from the sixth to the tenth

beneath it. In this case no actual gap appears. THE APPLICATION OF THE THEORY OF ELASTICITY TO TISSUE DAMAGE AND CYST FORMATION The brain, like inanimate substances, can be permanently damaged by being subjected to too great a stress. It is a priori not unreasonable to suppose that the criterion of permanent damage or injury to cerebral tissue is that the shearing stresses must exceed a certain critical value, just as with inanimate substances. Hence the liability to injury is proportional to the amount by which the stress departs from a purely hydrostatic

Since the cystic tumor was obviously too deep to be removed, the wound was closed carefully in layers as usual. The patient was in good condition at the end of operation.” Course . At the time of discharge 26 days after admission the patient had recovered remarkably. She was able to walk without assistance and the papilledema had almost entirely subsided. Interval Note .

. The scalp was reflected forward almost to the level of the supraorbital ridge. Periosteum was reflected from the loose frontal bone fragment, which was then removed. The dura was defective posteriorly where the propeller passed through it. The dura was turned forward as a flap. In the line of the initial injury the soft granulating cerebral tissue was resected en bloc . The underlying white matter was yellowish and contained innumerable cysts of various size. The right frontal cerebral lobe was amputated so far back as the pathological changes extended. This
