A series of 15 patients who underwent neurosurgical procedures for recurrent spheno-orbital meningioma is reported. There were 11 women and four men, with a mean age of 46 years. The mean duration between the first and second operations was 46 months. Progressive proptosis without neurological deficit was the most common symptom. All tumors were large at the time of reoperation and involved the greater and lesser wings of the sphenoid bone and the orbit. Aggressive resection in all patients resulted in no deaths and only slight morbidity, with the exception of one patient who developed blindness 24 hours after surgery due to central retinal artery occlusion. Fourteen patients were improved cosmetically and one patient, treated early in the series, had persistent proptosis due to inadequate bone removal. No attempt was made to remove tumor within the cavernous sinus in patients who were neurologically normal. Although postoperative imaging demonstrated complete gross excision of tumor in nine patients, 10 underwent conventional radiation therapy for residual tumor visualized at the time of surgery in the dura of the superior orbital fissure, the cavernous sinus, or the basal optic canal. Although this study is inconclusive and requires further long-term documentation, no recurrences have been seen to date in the follow-up period, ranging from 16 to 95 months. The following important points are discussed: 1) the failure by experienced surgeons to radically excise bone, tumor, and involved dura at the first operation; 2) the importance of early aggressive therapy, depending upon the patient's age and medical condition; 3) the almost invariable intracranial dural involvement, which at times was seen only by gadolinium-enhanced magnetic resonance imaging and not visualized on computerized tomography; 4) an illustrated stepwise surgical technique for complete resection through a small craniotomy without the need for complicated reconstruction of the orbit or temporal fossa; 5) the role of radiation therapy when removal is incomplete or deemed hazardous because of cavernous sinus involvement; and 6) the excellent cosmetic results possible with minimal morbidity and no mortality.

Transarterial NBCA embolization with the aid of a wedged catheter in flow-arrest conditions is a safe and an effective treatment for intracranial DAVFs.

Within the population of very severely head injured patients (GCS score 3-5), the simple combination of age and admission GCS score appears to predict accurately non-functional outcome in almost one third of patients. If confirmed at other centers, this may have wide-ranging implications regarding counseling of families, utilization of resources, and the design of head injury studies.
