Large basilar perforator pseudoaneurysm: A case report.

Basilar perforator aneurysms are rare and a communication between a basilar perforator and a separate pseudoaneurysm cavity is extremely rare. We describe a case presenting with high grade subarachnoid hemorrhage which on further investigation delineated a 2-3 mm dissecting basilar perforator aneurysm communicating superiorly into a contained 6 mm pseudoaneurysm cavity. This case illustrates an unusual neurovascular pathology with low potential for successful endovascular treatment such as coil embolization or intracranial flow diverter stenting.

Subjective and objective evaluation of image quality in biplane cerebral digital subtraction angiography following significant acquisition dose reduction in a clinical setting.

Objective: Different technical and procedural methods have been introduced to develop low radiation dose protocols in neurointerventional examinations. We investigated the feasibility of minimizing radiation exposure dose by simply decreasing the detector dose during cerebral DSA and evaluated the comparative level of image quality using both subjective and objective methods.

Methods: In a prospective study of patients undergoing diagnostic cerebral DSA, randomly selected vertebral arteries (VA) and/or internal carotid arteries and their contralateral equivalent arteries were injected.

Familial incidence of the congenital torcular dural arteriovenous shunt: Case report and review of the literature.

Congenital dural sinus malformations are rare but can be major causes of mortality and morbidity in the pediatric population if not detected and managed urgently. Lesions involving large draining sinus structures such as superior sagittal sinus and torcular herophili can result in significant intracranial circulation impairment mostly due to venous drainage disturbance. Early detection plays a pivotal role in the outcome of the patients.
