“…In our case 2, we did not consider embolization because many PICA aneurysms are dissecting- or pseudo-aneurysms,[111523] and thus are prone to perforation during coil embolization. [81018] However, our findings in case 1 suggest that the aneurysm in case 2 was a true aneurysm; therefore, endovascular treatment was an appropriate treatment option. We performed selective aneurysmal coil embolization and completed the procedure successfully without perforation.…”

BackgroundWhile hemodynamic stress can result in aneurysm formation, it rarely contributes to the development of peripheral aneurysms in collateral pathways. We report two patients with ruptured distal aneurysms in a collateral pathway associated with stenosis of a major cerebral artery.Case DescriptionA 67-year-old man presented with intracerebral hemorrhage in the right frontal lobe. Digital subtraction angiography (DSA) revealed severe stenosis of the right middle cerebral artery and two aneurysms in the collateral pathway of the right anterior cerebral artery. The ruptured aneurysm was trapped and resected; histologically, it was a true saccular aneurysm. The unruptured aneurysm was clipped and the patient was discharged without additional neurological deficits. The second patient was a 73-year-old woman with subarachnoid hemorrhage. DSA revealed three arterial dilations. On the 7th day of hospitalization, one of the aneurysms in a posterior inferior cerebellar artery–anterior inferior cerebellar artery anastomosis that functioned as a collateral pathway in the presence of severe basilar artery stenosis was found to be enlarged. It was treated by selective aneurysmal coil embolization with parent artery preservation. Her postoperative course was uneventful and she was discharged without any neurological deficits.ConclusionWe document the successful treatment of two patients with ruptured aneurysms in the peripheral portion of a collateral pathway. We discuss the histology of peripheral aneurysms and present a review of the literature.

“…In these diseases, myxoid degeneration of the wall may worsen the arterial damage, most commonly in the form of dissections. Some authors have found the presence of myxoid degeneration in apparently healthy arteries [10, 11, 12]. Our patient had no signs or history of the above-mentioned clinical entities.…”

“…With regard to extracranial arteries, there have been two reports of nondissecting aneurysms caused by myxoid degeneration in the cervical portion of the carotid artery [8, 9]. Four cases of intracranial dissecting aneurysms in adults have also been reported [10, 11, 12, 13]. Therefore, intracranial aneurysms with myxoid degeneration are extremely rare.…”

A 9-year-old girl presented with a subarachnoid hemorrhage. Cerebral angiography showed a saccular aneurysm arising from the horizontal portion of the right middle cerebral artery. The aneurysm was successfully clipped, and the dome of the aneurysm was excised for pathological study. Histological examination of the aneurysm wall showed that the entire thickness of the wall showed an increased myxoid degeneration. No dissection was present. Most intracranial aneurysms in childhood are believed to be of the saccular type similar to that in adults, but the pathogenesis of the aneurysm formation remains controversial. Myxoid degeneration may cause intracranial saccular aneurysm with eventual rupture, even in the absence of dissection. This is the first case reported of a ruptured saccular aneurysm caused by myxoid degeneration in a child. The possible pathophysiology is discussed.
