Review Case ReportsRuptured vertebral artery-posterior inferior cerebellar artery aneurysm associated with pulseless disease--case report.
A 48-year-old woman with a 29-year history of pulseless disease presented with subarachnoid hemorrhage caused by a rare ruptured intracranial aneurysm of the right vertebral-posterior inferior cerebellar artery. The aneurysm was successfully clipped. ⋯ Almost all patients have ischemic disorders of the involved vessels, manifesting as syncope, visual disturbance, or a faint or absent pulse. The mechanisms responsible for pulseless disease and intracranial aneurysms are likely to be different.

ReviewAssociation of paranasal sinus osteoma and intracranial mucocele--two case reports.
Two young adult males presented with paranasal sinus osteoma associated with mucocele. A 20-year-old man presented with headache and seizure, and another 20-year-old man presented with headache, frontal deformity, and visual disturbances. ⋯ The higher aggressiveness of the lesions may be due to the presence of the mucocele. Calcification and ossification of the mucocele probably contributes to the unexpected enlargement of the osteoma.

ReviewBranches of the anterior cerebral artery near the anterior communicating artery complex: an anatomic study and surgical perspective.
The anatomy of the branches of the anterior cerebral artery (ACA) near the anterior communicating artery (ACoA) complex were investigated to minimize neurovascular morbidity caused by surgical procedures performed in this region. Thirty-one cadaver brains were perfused with colored silicone, fixed, and studied under the operating microscope. The recurrent artery of Heubner (RAH), orbitofrontal artery (OFA), and frontopolar artery (FPA) were identified as the branches of the ACA arising near the ACoA complex. ⋯ The RAH, OFA, and the FPA are three branches that arise from the ACA near the ACoA complex. These vessels have similar diameters, but can be distinguished by the final destination. Distinguishing these vessels is important since the consequences of injury or occlusion of the FPA and OFA are significantly less than of the RAH.

Review Case ReportsAcute surgery for ruptured dissecting aneurysm of the M3 portion of the middle cerebral artery.
A 65-year-old woman presented with a ruptured dissecting aneurysm of the M3 portion of the middle cerebral artery (MCA) manifesting as disturbance of consciousness and motor aphasia. Computed tomography revealed subarachnoid hemorrhage. Emergent angiography demonstrated segmental aneurysmal dilatation of the M3 portion of the left MCA. ⋯ Distal dissecting aneurysm may occur in the absence of infectious disease. Such ruptured distal dissecting aneurysm should preferably be treated surgically in the acute stage, immediately after detection of the aneurysm. The parent artery of the proximal and distal sides of the aneurysm should be trapped because of the probable weakness of the arterial wall, and bypass surgery performed to preserve the distal circulation.
