✓ Three cases of large supratentorial teratomas in patients under 1 year old are reported. One 320-gm tumor was successfully totally removed; one patient died without surgery 7 days after birth, and one died 10 days after subtotal removal. The symptoms and diagnosis of intracranial teratomas in infancy are discussed. Treatment by total removal is recommended.

✓ Anterior clinoidal meningiomas are frequently grouped with suprasellar or sphenoid ridge meningiomas, masking their notorious association with a high mortality and morbidity rate, failure of total removal, and recurrence. To avoid injury to encased cerebral vessels, most surgeons are content with subtotal removal. Without total removal, however, recurrence is expected. Recent advances in cranial-base exposure and cavernous sinus surgery have facilitated radical total removal. The author reports 24 cases operated on with vigorous attempts at total removal of the tumor with involved dura and bone. This experience has distinguished three groups (I, II, and III) which influence surgical difficulties, the success of total removal, and outcome. These subgroups relate to the presence of interfacing arachnoid membranes between the tumor and cerebral vessels. The presence or absence of arachnoid membranes depends on the origin of the tumor and its relation to the naked segment of carotid artery lying outside the carotid cistern. Total removal was impossible in the three patients in Group I, with postoperative death occurring in one patient and hemiplegia in another. Total removal was achieved in 18 of the 19 patients in Group II, with one death from pulmonary embolism. In the two patients in Group III, total removal without complications was easily achieved.

✓ An operative technique for total removal of large global meningiomas at the medial aspect of the sphenoid ridge is described, and experience with 11 patients reported. The technique involves extradural liberation of the dural and tumor attachments to the underlying bone, and extradural occlusion of the blood supply through bone and middle meningeal artery. Subsequent procedures are carried out sequentially in the parasellar area to free the optic nerve and carotid, in the subtemporal tentorial region to release tumor from neighboring structures, and in the Sylvian fissure to isolate the middle cerebral artery.

✓ Experience with large cerebral abscesses in six newborn or very young infants is the basis for this report and discussion. Hydrocephalus, an afebrile state, and an elevated white blood cell count were characteristic. Diagnosis by aspiration was usually fortuitous in the process of subdural tap or ventriculography. Treatment by multiple aspirations was reasonably successful, but ultimate excision of the shrunken abscess may be wise. In only one case was the source of infection obvious.

✓ A series of 250 surgically treated cerebral arteriovenous malformations (AVM's) is presented, in which 22 lesions were located primarily in the thalamus and caudate nucleus. A standardized interhemispheric approach through the posterior corpus callosum and into the atrium of the lateral ventricle was utilized for the surgical removal of these AVM's. Total removal was confirmed by angiography in 18 patients; removal was subtotal in four cases. There were no deaths in this group of patients. Disturbances of recent memory pre- and postoperatively were seen in half of the patients, but most of these deficits were temporary. Other complications included: postoperative homonymous hemianopsia (six cases), transient hemiparesis (three cases), hemisensory loss (two cases), Parinaud's syndrome (one case), and recurrent hemorrhage 2 years after surgery (one case). All 22 patients returned to their previous occupations and are leading independent lives. The results of this experience indicate that thalamocaudate AVM's can be effectively treated by resection.

Object. The extended transsphenoidal approach, which requires a bone and dural opening through the tuberculum sellae and posterior planum sphenoidale, is increasingly used for the treatment of nonadenomatous suprasellar tumors. The authors present their experiences in using the direct endonasal approach in patients with nonadenomatous suprasellar tumors. Methods. Surgery was performed with the aid of an operating microscope and angled endoscopes were used to assess the completeness of resection. Bone and dural defects were repaired using abdominal fat, collagen sponge, titanium mesh, and, in most cases, lumbar drainage of cerebrospinal fluid (CSF). Twenty-six procedures for tumor removal were performed in 24 patients (ages 9–79 years), including two repeated operations for residual tumor. Gross-total removal could be accomplished in only 46% of patients, with near-gross-total removal or better in 74% of 23 patients (five of eight with craniopharyngiomas, six of seven with meningiomas, five of six with Rathke cleft cysts, and one of two with a dermoid or epidermoid cyst); a patient with a lymphoma only underwent biopsy. Of 13 patients with tumor-related visual loss, 85% improved postoperatively. The complications that occurred included five patients (21%) with postoperative CSF leaks, one patient (4%) with bacterial meningitis; five patients (21%) with new endocrinopathy; and two patients (8%) who needed to undergo repeated operations to downsize suprasellar fat grafts. The only permanent neurological deficit was anosmia in one patient; there were no intracranial vascular injuries. Conclusions. The direct endonasal skull-base approach provides an effective minimally invasive means for resecting or debulking nonadenomatous suprasellar tumors that have traditionally been approached through a sublabial or transcranial route. Procedures in the supraglandular space can be performed effectively with excellent visualization of the optic apparatus while preserving pituitary function in most cases. The major challenge remains developing consistently effective techniques to prevent postoperative CSF leaks.

✓ A patient is reported with a purely pial arteriovenous malformation (AVM) supplied from the posterior parietal artery. The prominent middle meningeal artery contributed to opacification of the angular branches distal to the AVM, but did not contribute to the AVM. After total removal of the AVM, the angular branches became opacified from the middle cerebral artery. Review of the literature suggests that hypertrophied dural arteries which do not contribute to the AVM's but which do opacify the cortical branches distal to the AVM's are rare.

✓ A case of a cavernous angioma of the cauda equina is presented. The patient was a 28-year-old man who experienced sudden low-back pain and headache without neurological symptoms. Lumbar puncture revealed subarachnoid hemorrhage. He had suffered a similar episode 3 years previously. Selective spinal angiography did not demonstrate any abnormal vascularity. Metrizamide myelography and magnetic resonance imaging were useful in demonstrating the presence of a tumor. Laminectomy at L1–3 and total removal of the tumor were performed without neurological deficit.

Object. The goal of this study was to provide epidemiological and clinical data on the management of cavernomas of the basal ganglia and brainstem from a long-term series at one institution. Methods. All 68 patients who were referred to the authors' department between 1992 and 2000 for deep cavernomas were evaluated by clinic examinations, review of neuroimaging examinations, and review of charts and operative notes. Twenty-nine patients underwent microsurgical procedures, which carried a 69% risk of transitory neurological deterioration. Radical excision was achieved in 25 of these patients, as determined by a review of neuroimages; the remaining four patients all experienced new hemorrhages that led to increased morbidity or even to mortality. Surgical results were better if surgery was performed early, within 1 month posthemorrhage, than if operations were postponed. In selected patients, deep lesions not reaching a pial surface could be safely removed from the thalamus, basal ganglia, or medulla oblongata. Of five patients who underwent gamma knife surgery, two experienced hemorrhages, one at 2 and the other at 5 years following treatment. Patients who did not undergo surgery had a yearly incidence of hemorrhage that was 2% in cases of incidental cavernomas and 7% in symptomatic ones. Conclusions. Over the long term, outcomes were worse following conservative treatment or shunt insertion surgery than after microsurgery of symptomatic cavernomas. Incidental cavernomas carried a low risk of neurological deterioration. Surgery should follow generally accepted indications, but only with the confidence that total removal can be safely achieved. Surgery that is performed within 10 to 30 days following ictus may be preferable to delayed surgery.
