sclerosis were seriously considered; (2) the thoracic site of the tumor; (3) the associated syrinx; and (4) the possibility of a multiple process, suggested by the fact that the “glove” hypesthesia and paresthesia vanished after operation. Perhaps a syringomyelic cavity of the cervical cord may have been drained through the central canal when the cord was opened at the thoracic level. The difficulty of early diagnosis in this and similar cases should carry a note of warning, especially since remissions may occur during the development of neurological symptoms and signs

scar on microscopic examination. The hard gritty band of scar tissue was excised, together with about 3 cm. of the distal stump. In this was found a fair-sized syrinx occupying the ventral half of the gray matter and extending from the site of the lesion well beyond the lower limits of the excision and the surgical exposure. Immediately after the operation, the patient had continuous clonic spasms of his legs which lasted for 12 hours, thus proving the absence of spinal shock following secondary transection in this case. After that, spontaneous reflex spasms

The Surgical Treatment of Arnold-Chiari Malformation in Adults

An Explanation of Its Mechanism and Importance of Encephalography in Diagnosis

W. James Gardner and Robert J. Goodall

similarity of the appearance of the cerebellar tonsils in platybasia and in Arnold-Chiari malformation. He believes that the accumulating cerebrospinal fluid in these cases may dilate the central canal with resulting hydromyelia and may also perforate the ependymal lining with the formation of a syrinx. Ingraham and Scott 11 in 1943 presented an excellent review of the literature and described 20 cases of Arnold-Chiari malformation in infants associated with myelomeningocele. The majority of their patients had associated microgyria and craniolacunia but only 2 had

closed. A syrinx below the tumor explained the block at the 4th thoracic level. Microscopic Examination . The tumor was very vascular. It was composed of spindle-shaped cells with indistinct cell borders and with dark-staining nuclei that showed little variation in size and shape. Occasional ovoid areas of hyalinized material were present and blood vessels with partially hyalinized walls were visualized. In spite of the absence of radial arrangement, the individual cellular elements were considered characteristic of ependymoma. Course . Following surgery symptoms

chain or ganglia may presumably result in hyperhidrosis during a stage of irritation; that is, before a pathological sympathectomy by tumor compression or invasion has occurred, although the author has not seen such a phenomenon. In this case the differential diagnosis on clinical grounds lay between intrinsic disease of the spinal cord such as a glioma or syrinx, and an extradural or paravertebral tumor such as a dumb-bell type of ganglioneuroma, neuroblastoma, or neurofibroma. The absence of spinal cord signs and the subsequent normal cerebrospinal fluid and

trauma of several laminectomies that had been done, caused a proliferation of connective tissue in the leptomeninges, leading to infarction of the cord and subsequent formation of syrinx. Finneson et al. 24 reported the history of a 64-year-old woman, with known Paget's disease, who exhibited the syndrome of acute compression of the cauda equina. Laminectomy revealed an osteogenic sarcoma arising in the lumbar vertebrae involved in the osteitis deformans. Berthold 10 has pointed out that spinal epidural granulomas may cause a transverse lesion of the cord in much

Embryonal Atresia of the Fourth Ventricle

The Cause of “Arachnoid Cyst” of the Cerebellopontine Angle

. Unfortunately, the spinal cord was not removed at necropsy. The diverticulum of the left lateral ventricle resembled those diverticula described by Northfield and Russell. 15 This lesion, we believe, has the same significance and is produced by the same cause as a syrinx of the cord; namely, by a rupture of the ependymal lining and creating of a blind passage of fluid extruded as a result of increased pressure within the lumen of the neural tube. The constricting band of meninges at the level of the foramen magnum in this case was similar to that encountered in other

Vertebral Artery Insufficiency in Acute and Chronic Spinal Trauma

With Special Reference to the Syndrome of Acute Central Cervical Spinal Cord Injury

Richard C. Schneider and George W. Schemm

gradual destruction of the spinal cord from atrophy. If it is more acute with infarction then liquefaction and formation of syrinx might occur. Obviously not all cases of syringomyelia will occur in this way, but it may be that a few may have this etiology. Further studies are being performed along these lines. SUMMARY In traumatic cervical injuries the acute central cervical spinal cord injury is characterized by more motor power in the lower extremities than in the upper ones with a varying degree of associated sensory loss. The lesion may be caused by: 1

AXIAL MYELOGRAPHY Contrast myelography of the clivus and foramen magnum may be indicated when air fails to give accurate information in suspected tonsillar hernia, Arnold-Chiari malformation, high cord tumor or syrinx, prepontine and foramen-magnum lesions. Forward rotation to the vertex-down position will bring the medium to the clivus. Reverse turn
