OBJECTIVE To present results of early angiographic diagnosis and endovascular treatment of traumatic intracranial aneurysms (TICA). METHODS From June 2002 to December 2006, diagnostic angiography was performed on patients with moderate to severe traumatic brain injury that involved a cranial base fracture or a penetrating brain injury with a tract from(More)
Six patients are reported with nephrotic syndrome and relatively rapid progression to irreversible renal failure. The renal histologic findings are unusual. The most striking changes are collapse of glomerular capillary loops, such as might occur with glomerular hypoperfusion; significant tubulointerstitial damage is also seen. These patients appear to have(More)
There is limited data on the genetic origin and natural history of cerebellar liponeurocytoma. To the best of our knowledge there has been only one report of a familial presentation of this rare entity. We report a 72-year-old female with a posterior fossa tumor presenting with progressive cerebellar signs and symptoms. The patient underwent total tumor(More)
Endoscopic techniques are an integral part of the neurosurgical armamentarium with a growing list of indications. We describe the purely endoscopic removal of an atypical parasagittal meningioma in a patient who could not undergo standard craniotomy due to severe scalp atrophy following childhood irradiation for tinea capitis. A 68-year-old man in good(More)
BACKGROUND We evaluate a new technique for plateless fixation of a bone flap after fronto-orbital craniotomy. METHODS From September 1999 to October 2004, we performed fronto-orbital craniotomy reconstruction using the Craniofix titanium clamp in 108 consecutive patients with a variety of lesions in the anterior skull base. Postoperative computed(More)
Aneurysmal bone cyst (ABC) is a benign cystic lesion characterized by blood filled cyst-like cavities separated by connective tissue septa containing spindle cells, osteoclasttype multinucleated giant cells and reactive woven bone or osteoid [7]. Most ABCs arise de novo (primary ABC), but others (secondary ABC) are associated with another benign or(More)
The sitting position during surgery is thought to provide important advantages, yet it remains controversial. We compared surgical and neurological outcomes for patients operated on in the sitting versus lateral position. Technically difficult procedures performed from the years 2001-2008 for complex lesions in the posterior fossa (vestibular schwannomas,(More)
