Contralateral approach to giant ruptured and unruptured ophthalmic artery aneurysms: patient series.

Background: Giant ophthalmic artery (OphA) aneurysms remain surgically challenging despite the progress in endovascular treatments. This study describes the contralateral interoptic corridor in select patients based on imaging criteria suitable for clipping. The aim of this study was to show that despite the growing use of novel endovascular techniques, such as coil embolization and flow diversion, for the treatment of OphA aneurysms, microsurgical clipping may still be preferred for giant ones under certain conditions.

Early reappearance of disappeared ruptured small aneurysm with concomitant vertebral artery dissection.

Thrombosis of a previously ruptured intracranial aneurysm is a frequent event and it most commonly occurs in large or giant aneurysms. We present a dynamic short-term follow-up and management of thrombosis in a ruptured small posterior inferior cerebellar artery aneurysm with concomitant vertebral artery dissection (VAD). Clinical and radiological follow-up findings and reviewed literature on thrombosis of small ruptured aneurysms are the focus of this presentation.

Cerebral proliferative angiopathy with tumor-like hemorrhage: A case report and literature review.

Cerebral proliferative angiopathy (CPA) is defined as a rare vascular disorder, characterized by diffuse arterial proliferation and distinctive angiogenetic features. Complication with hemorrhage is exceedingly rare, but once the bleeding occurs, the chance of re-bleeding is increased. Here we report a case of a patient with CPA complicated with bleeding and re-bleeding, and imaging findings mimicking a brain tumor, which has not been reported in the literature so far.

Kinetic evaluation of low-grade gliomas in adults before and after treatment with CCNU alone.

Object: The aim of this study was to evaluate the impact of CCNU chemotherapy alone on low-grade glioma (LGG) growth dynamics.

Methods: The authors measured the evolution of the mean tumor diameter (MTD) in adult patients with LGG before (n=28 patients) and after (n=38 patients) CCNU administration.

Results: Natural (spontaneous) growth of LGG in the present study was 4.
