The records of 137 patients with supratentorial oligodendroglioma treated surgically between 1953 and 1986 were reviewed. The tumors were rated histologically benign or malignant. In the 105 patients followed up with a minimum observation time of 5 years to December 1991, the mean postoperative survival was 90.2 months (standard error, 9), the median 64(More)
This report presents a retrospective prognostic study of 65 patients with intramedullary astrocytoma surgically treated between 1953 and 1990. Median survival and statistical survival at 5 years were assessed in relation to clinical, histological and therapeutic factors for each patient. Results showed that factors positively influencing the prognosis are(More)
The precise localizations of the neural substrates of voluntary inhibition are still debated. It has been hypothesized that, in humans, this executive function relies upon a right-lateralized pathway comprising the inferior frontal gyrus and the presupplementary motor area, which would control the neural processes for movement inhibition acting through the(More)
With the aim of understanding better the behaviour of an uncommon lesion such as the choroid plexus papilloma, we have analysed a surgical series of 33 cases operated on at the Neurosurgical Department, University of Rome “La Sapienza”, between 1955 and 1992 and have reviewed the relevant literature. Our results support the view that a radical resection of(More)
Glioblastoma multiforme (GBM) is a diffuse brain tumor characterized by high infiltration in the brain parenchyma rendering the tumor difficult to eradicate by neurosurgery. Efforts to identify molecular targets involved in the invasive behavior of GBM suggested ion channel inhibition as a promising therapeutic approach. To determine if the Ca(2+)-dependent(More)
To contribute to a better understanding of the prognostic differences between atypical and malignant meningiomas as defined by the World Health Organization (WHO) and the influence of the grade of initial surgical excision on postoperative course, 42 cases of atypical and 29 of malignant meningioma were studied, along with long-term follow up. The two(More)
Forty-five (9.9%) of 453 pituitary adenomas operated on between January 1973 and November 1988 demonstrated hemorrhagic changes at surgery: 24 had a blood collection, 12 had a blood collection associated with hemorrhagic necrosis, and 9 had hemorrhagic necrosis. Thirteen patients (28.9%) experienced the acute symptoms of pituitary apoplexy, whereas another(More)
BACKGROUND We review the surgical anatomy of the brain stem in relation to the surgical approaches adopted for treatment of cavernomas and identify possible "safe entry zones" on the anterior face of the brainstem. METHODS Twelve symptomatic patients with cavernoma or telangectasia of the brain stem were surgically treated. The brain stem was divided into(More)
This retrospective study focuses on 14 patients with ganglioglioma of the cerebral hemispheres who received surgical treatment in the Neurosciences Department/Neurosurgery of “La Sapienza” University of Rome between 1953 and 1990. The data are analyzed together with those on 98 published cases of ganglioglioma confined to the cerebral hemispheres. These(More)
BACKGROUND Intraventricular neoplasms are rare tumours (1% of the tumours of the central nervous system). The surgical approach sometimes is quite difficult, particularly in the dominant hemisphere. The best choice of surgical approach is discussed. METHODS The authors describe a series of 25 patients who underwent surgical treatment for tumours situated(More)
