The authors present a case of chondrosarcoma involving the lateral mass of the C-2 vertebra, treated by an apparent total removal of the tumor. A review of the literature revealed that these patients can be cured in a significant number of cases if a radical removal is accomplished.
In recent years the traditional pathway for position sense in the lower extremities has been challenged and it has been proposed that in the upper spinal cord the relevant fibres ascend not in fasciculus gracilis but in the dorsolateral part of the lateral funiculus with the dorsal spinocerebellar tract. To determine whether this premise is correct we have… (More)
With the introduction of additional diagnostic methods, computerized axial tomography, interventricular tumors are discovered at a time when these lesions are still small and may have presented very insignificant or no clinical symptoms. If the lesion is a benign tumor as a meningioma and within the lateral ventricle of the dominant hemisphere a very… (More)
A case of plasmacytoma of the clivus is presented. The patient was asymptomatic until a coincidental traumatic lesion produced manifestations of vagus nerve dysfunction. Conduction was blocked in some fibers of the vagus nerve while, at the same time, episodes of activity were triggered in fibers of the same nerve trunk, resulting in an unusual combination… (More)
That blood in the subarachnoid space could possibly produce hydrocephalus was first suggested by Bagley in 1928 (3, 4). His conclusions were based on both experimental and clinical studies even though he actually failed to demonstrate a communicating hydrocephalus. Subsequent workers have repeatedly demonstrated leptomeningeal thickening associated with… (More)
Intraoperative stimulation of the distal section of the facial nerve was performed in 29 patients undergoing surgery for glomus jugulare tumor. A definite and persistent topical anatomical arrangement was observed.
The diagnosis and successful treatment of a cerebral aneurysm in a 1-month-old child are described. A review of the few aneurysms previously recorded in children up to three months of age reveals that such aneurysms tend to be large, but show no predilection for any particular site, although a relatively large number of them arise from the vertebrobasilar… (More)
The main anastomotic collaterals between intrathecal and extracranial arteries are shown in a tumor of the glomus jugulare. The significance of these collaterals in embolization therapy is pointed out.
