acting on normal, or even thinned dura could produce the same necrosis. As an alternative to this concept, we suggest that a defect in closure of the dura at an early age might cause hypoplasia of the surrounding bone, which alteration might persist through the growth period to finally result in meningocele formation. SUMMARY 1. Five of 8 cases of lateral intrathoracic meningocele have been associated with gross von Recklinghausen's disease. This establishes a strong presumption of common etiology. 2. We suggest that these lesions result from

cyanotic, and respiration rather rapidly became stertorous and irregular. He expired quickly without responding to any further treatment. Autopsy . Examination confirmed the operative observation of atresia of the esophagus with marked separation of the two segments. The tracheo-esophageal fistula had been successfully ligated, but there was some mediastinitis near the operative area. Multiple other anomalies were noted. There was a marked hypoplasia of the right kidney with a levoposition, and an anomalous right ureter. There was a Meckel's diverticulum, and an

carotid artery may be obtained by carotid angiography, which readily discloses to what extent one hemisphere may be supplied by arterial blood from the carotid on the opposite side. We shall attempt to demonstrate the collateral circulation which is called into activity in cases of obliteration of the internal carotid artery (1) at its beginning near the bifurcation of the common carotid artery; (2) at the point where the internal carotid artery bifurcates into the anterior and middle cerebral arteries; and (3) in cases of hypoplasia of the internal carotid artery

failure ensued. In spite of the aid of a respirator, stellate ganglion procaine blocks, serum albumin, plasma, lumbar punctures, metrazol and caffeine, death occurred. Postmortem examination confirmed the clinical evidence of cerebral edema with additional pathologic findings: 1) Bilateral gasserian ganglionitis, chronic, severe; 2) marked cerebral edema with pressure cone formation at the foramen magnum; 3) persistent thymus and relatively large lymph nodes; 4) hypoplasia of the breasts and mild hirsutism; 5) probable mild platybasia.

Cerebellar symptoms such as asynergia, dysmetria, ataxia, hypotonia and disturbances of balance were evident in 11 cases. Nystagmus or nystagmoid movements appeared in 6 patients with histologically verified neoplasms and in 3 of those diagnosed by clinical examination. Endocrine and hypothalamic disturbances were found in 17 cases: 1 female suffered from amenorrhea and another had poorly developed secondary sexual characteristics; 2 males had infantile genitalia with hypoplasia of the testes. The syndrome of precocious puberty was not diagnosed in any of the 32 cases

have been some improvement in the hemiparesis. This is difficult to interpret, however, as the patient has been receiving physiotherapy. Case 7 . Unit No. 068950. P.C., a 4½-year-old girl, was admitted on Nov. 10, 1951, because of severe left hemiparesis and bulging in the right parietal region which had become progressively more prominent. At the age of 2 she had fallen 15 feet, striking her head on a stone walk. She had been semicomatose for about 6 weeks. Neurological findings on admission were a spastic left hemiparesis with hypoplasia of the left extremities

. Extracranial anomalies and malformations have frequently been reported as associated with cerebral aneurysms 4 but were present in only 9 patients in this group. Patent foramen ovale or fenestration of the aortic valves was noted in 4, polycystic disease of the kidney in 1, and horseshoe kidney in another. Hypoplasia of one kidney or one adrenal was noted twice, reduplication of the ureter, once. Anomalous formation of the circle of Willis in the presence of cerebral aneurysm, however, was present in 118 of the 124 cases in which complete description was available

addition to severe diabetic nephropathy, hypoplasia of the pancreas, and extensive necrosis of the pituitary ( Figs. 3 and 4 ). (3) In C.J.E. an unexplained intracerebral hemorrhage developed as soon as the optic nerve was exposed. There was a sudden rise in blood pressure, with marked herniation of the frontal cortex through the trephine. Twenty-five cc. of intracerebral blood were aspirated, but it was necessary to resect the tip of the frontal lobe. This was the only patient in our series on whom a partial frontal lobectomy was done. The pituitary stalk was

The anterior margin of the left orbit was much larger than that of its mate on the right side. Fig. 6. Case 2 . Radiograph of skull, anteroposterior projection, showing aplasia of left sphenoid with absence of posterior wall of left orbit, expansion of left orbit anteriorly and compression of left ethmoidal air cells.
