Abstract BACKGROUND We report an unusual case of a true dural aneurysm arising from the posterior meningeal artery that fed a symptomatic dural arteriovenous fistula located at the right transverse-sigmoid sinus junction. CLINICAL PRESENTATION A 29-year-old right-handed white woman presented with aneurysmal dilatation of hypertrophied posterior meningeal artery feeding a partially treated dural arteriovenous fistula. INTERVENTION The aneurysm, which measured approximately 3 mm in width and 5 mm in length, was located in the intracranial space with a thin-walled dome projecting toward the cerebellum. Its afferent and efferent vessels were identified, secured, and the lesion was excised en bloc. CONCLUSION A thorough evaluation of all diagnostic studies should be performed for patients with vascular malformations to help identify these or other unusual lesions that may aid in the risk stratification process and management plan.

Abstract OBJECTIVE This is the first report of a ruptured aneurysm involving a collateral branch to the posterior inferior cerebellar artery (PICA) in a patient who had a subarachnoid hemorrhage. CLINICAL PRESENTATION A 56-year-old man initially presented with a subarachnoid hemorrhage and underwent 2 catheter-based 4-vessel angiograms with negative results. A delayed angiogram 4 weeks later revealed a dissecting aneurysm of the posterior meningeal artery, a branch of the vertebral artery. INTERVENTION A 3-dimensional reconstruction of the vertebral angiogram showed proximal occlusion of the proximal left PICA and distal filling via a collateral branch from the posterior meningeal artery. A far-lateral approach was used for this patient. The aneurysm was found along the course of the collateral posterior meningeal artery and was clipped successfully. CONCLUSION Aneurysms involving collateral branches of the PICA are rare. It is important to recognize such collateral flow preoperatively because inadvertent sacrifice of these vessels during a surgical approach could lead to stroke and neurological deficits of the PICA territory.

ABSTRACT OBJECTIVE The posterior meningeal artery (PMA) normally arises from the vertebral artery; however, its origin varies considerably as the result of its embryological development. This gains clinical significance when associated with vascular pathology. CLINICAL PRESENTATION A 65-year-old man presented to his local hospital with a sudden-onset, severe headache. Computed tomography of the head revealed diffuse subarachnoid hemorrhage, mostly in the left posterior fossa. A computed tomographic angiogram demonstrated an anomalous origin of the PMA from the posteroinferior cerebellar artery (PICA). Cerebral angiography showed the PICA to be enlarged, with a reduced caliber at the takeoff of the PMA, which is consistent with possible dissection. INTERVENTION The patient was taken to the operating room for trapping of the dissecting segment of the PMA. A clip was placed across the PMA at its origin from the PICA, and the vessel was coagulated and transected. The PICA was wrapped in muslin gauze. CONCLUSION The variable origin of the PMA and PICA may be the result of the persistence of embryological anastomoses between the arteries, with regression of the normal channel. Physical stress at the junction of the anomalous PMA and the PICA may have contributed to the abnormality of the PMA, consistent with possible dissection. Because the PMA has multiple anastomoses with the arteries of the falx cerebri, the proximal PMA may be occluded with no compromise to its vascular territory.
