International Journal of Radiation Oncology Biology Physics, 83(5), E633-E637. Purpose: To evaluate the efficacy of fractionated proton radiotherapy for a population of patients with benign cavernous sinus meningiomas. Methods and Materials: Between 1991 and 2002, 72 patients were treated at Loma Linda University Medical Center with proton therapy for cavernous sinus meningiomas. Fifty-one patients had biopsy or subtotal resection; 47 had World Health Organization grade 1 pathology. Twenty-one patients had no histologic verification. Twenty-two patients received primary proton therapy; 30 had 1 previous surgery; 20 had more than 1 surgery. The mean gross tumor volume was 27.6 cm(3); mean clinical target volume was 52.9 cm(3). Median total doses for patients with and without histologic verification were 59 and 57 Gy, respectively. Mean and median follow-up periods were 74 months. Results: The overall 5-year actuarial control rate was 96%; the control rate was 99% in patients with grade 1 or absent histologic findings and 50% for those with atypical histology. All 21 patients who did not have histologic verification and 46 of 47 patients with histologic confirmation of grade 1 tumor demonstrated disease control at 5 years. Control rates for patients without previous surgery, 1 surgery, and 2 or more surgeries were 95%, 96%, and 95%, respectively. Conclusions: Fractionated proton radiotherapy for grade 1 cavernous sinus meningiomas achieves excellent control rates with minimal toxicities, regardless of surgical intervention or use of histologic diagnosis. Disease control for large lesions can be achieved by primary fractionated proton therapy. (C) 2012 Elsevier Inc. (08/2012) (link)

INTRODUCTION: Neurosurgical treatment of spontaneous intracerebral hemorrhage (ICH) is controversial, with a lack of evidence-based guidelines contributing to the high variety of treatments. In our study we examine the outcome and complication from use of intralesional tissue plasminogen activator (IL tPA). METHOD: Patients who have been treated with IL tPA for spontaneous ICH were reviewed retrospectively. We compared clot sizes before and after tPA infusion, and outcome based on the modified Rankin score. RESULTS: Nine patients received IL tPA during the period 1999-2009. No immediate complications with use of IL tPA were found. There was a statistically significant volume reduction in clot sizes on computed tomography. Four patients recovered to independent functional status. Three patients were discharged to SNF, and two patients died as a result of ICH. Our results appear to demonstrate superior outcome to supportive management and no worse result than surgical management. CONCLUSION: It appears a subset of ICH patients benefits from use of IL tPA. This study demonstrates that IL tPA use is safe and has the potential to improve outcome compared to conservative management without the risk of surgical complications. Our patient size is small, and larger prospective studies are needed to provide solid guidelines for management of ICH. (2011) (link)
• Johnson W D, & Petrie M M. (2009). Variety of spinal vascular pathology seen in adult Cobb syndrome Report of 2 cases. Journal of Neurosurgery-Spine, 10(5), 430-435. Cobb syndrome is a rare clinical entity that includes the combination of a vascular skin nevus and an angioma in the spinal canal present at identical dermatomal level(s) (cutaneomeningospinal angiomatosis). To date, 38 cases have been reported, only 18 of which are in adults (> 18 years of age). The majority of these cases have been described in the era predating current neuroimaging techniques, and most authors have assumed that each case involves similar vascular pathology. This report highlights 2 patients presenting with similar thoracic cutaneous vascular nevi yet with markedly differing spinal vascular pathology. A 29-year-old man presented with cutaneous hemangioma and a progressive paraparesis and paresthesia of the lower extremities. A 20 x 20-cm port-wine stain over his right upper midback (T6-10) correlated precisely with MR imaging that demonstrated an enhancing epidural mass between T-6 and T-10 causing compression of the cord and cord edema. A 34-year-old man also presented with progressive myelopathy and a 15 x 20-cm port-wine stain within the same dermatomal region as a Type III spinal arteriovenous malformation. Workup for each patient included pre- and postoperative contrast-enhanced MR imaging with vascular sequencing and spinal angiography. The first patient was treated with bilateral laminectomy at the T6-10 levels, with significant postoperative improvement in motor strength. The second patient underwent coil embolization of an intranidal aneurysm, with follow-up embolization 8 years later. Cobb syndrome is an unusual entity in the adult population and should be considered when there is a constellation of cutaneous manifestation and underlying neurological deficit. The vascular skin nevus associated with Cobb syndrome is accompanied by a wide variety of vascular pathologies. (DOI: 10.3171/2009.1.SPINE08334) (05/2009) (link)
