Objectives: To describe the clinical course, image findings and literature review of choroidal fissure cysts. summary and background data: there are few reported cases of choroidal fissure cysts. Results: We report two patients with complex partial seizures and temporal choroidal fissure cysts. The seizures were controlled in both patients. Conclusion: The choroidal fissure cyst diagnosis must highlight the importance of considering this lesion in the differential diagnosis of temporal lobe cyst and temporal lobe seizure. REsumO Cistos da fissura coroidal temporal e epilepsia do lobo temporal: dois relatos de casos Desenho do estudo: Dois relatos de caso de cisto de fissura coroidal no corno temporal associado com crise parcial complexa. Objetivos: Descrever o curso clínico, achados radiológicos e fazer uma revisão da literatura a respeito de cistos da fissura coroidal. Resumo dos dados da literatura: existem poucos casos descritos de cistos da fissura coroidal. Resultados: Nós descrevemos dois pacientes com crises parciais complexas e cistos de fissura coroidal. As crises foram controladas em ambos os pacientes. Conclusão: O diagnóstico de cisto da fissura coroidal deve ser levado em conta no diagnóstico diferencial de cistos do lobo temporal e em crises de lobo temporal.

Small aneurysms are more prevalent than large aneurysms in patients with ruptured aneurysms. P2 and P3 aneurysms are usually managed by the subtemporal approach. This is a case report of rupture saccular aneurysm of posterior cerebral artery on P2P segment. The authors show the surgical steps of these rare aneurysms with an illustrative case.

Design Case report. Setting University hospital. Participants Four cases. Main Outcome Measures Postoperative course after EC-IC bypass surgery. Results In case 1, the parent vessel was occluded postoperatively. The radial bypass was sufficient to replace the internal carotid artery (ICA) flow, and a prophylactic was turned into a definitive bypass. In case 2, the superior thyroid artery was used because the radial artery was not long enough to reach the external carotid artery. The recipient vessel was modified from the middle cerebral artery to the ophthalmic segment of the ICA. In case 3, the graft was occluded after surgery because of carotid artery reconstruction. In case 4, after surgery/radiotherapy for meningioma, the patient developed wound de...
