Hydatid cysts of the brain are very rare. Exceptionally, signs and symptoms are primarily those of acute cerebral ischaemia. Two cases of acute cerebral ischaemia are reported in a 21 year old and 40 year old women. A computed tomographic scan revealed a middle cerebral artery (MCA) infarct and an abrupt cutoff of the MCA at cerebral angiography. A few months later, a CT scan showed cysts in the territory of the infarct. Hydatid cysts were also found in multiple viscera, particularly in the heart. These two observations and some cases reported in the literature suggested that the myocardial cyst may have ruptured into the ventricular cavity, resulting in widespread intravascular dissemination of embryo and causing an acute cerebral infarction. The interest of these cases lies in the rarity of an acute cerebral ischaemia due to hydatid cyst embolism, and in the early diagnosis of cardiac cysts in young patients.
脑包虫囊肿非常罕见。极个别情况下，体征和症状主要表现为急性脑缺血。本文报告了2例急性脑缺血病例，患者分别为一名21岁女性和一名40岁女性。计算机断层扫描显示大脑中动脉（MCA）梗死，脑血管造影显示MCA突然中断。几个月后，CT扫描显示梗死区域有囊肿。在多个脏器中也发现了包虫囊肿，尤其是心脏。这两例观察结果以及文献中报道的一些病例表明，心肌囊肿可能已破裂进入心室腔，导致胚胎在血管内广泛播散并引起急性脑梗死。这些病例的意义在于因包虫囊肿栓塞导致急性脑缺血的罕见性，以及对年轻患者心脏囊肿的早期诊断。
