Ovarian hyperstimulation syndrome (OHSS) is a potentially serious complication occurring in ovarian induction therapy. We report a case of ischemic stroke with OHSS. Previously healthy 33-year-old woman underwented In vitro fertilization-Embryo transfer (IVF-ET) 6 days ago. She admitted for dyspnea and abdominal distension. Chest X-ray arid simple abdomen showed massive pleural effusion and ascites. Left hemiparesis and sensory extinction were developed suddenly 2days after admission. She was administrated with recombinant tissue-plasminogen activator (rt-PA) intravenously witin 3hours of symptom onset. Hemiparesis was improved remarkably after rt-PA infusion. Magnetic resonance imaging showed acute ischemic infarction on the right basal ganglia, corona radiata, temporal lobe and parietal lobe, and left frontal lobe, and parietal lobe. Laboratory studies showed Hemoconcentration (hematocrit: 50.4%), elevated D-dimer and fibrinogen (5.03 μg/mL and 406 mg/dL respectively) and decreased protein S activity (51%). 20 days after admission, she discharged without neurologic sequelae. Screening test for hypercoagulable state should be considered before ovulation induction therapy to prevent cerebrovascular complication with OHSS.

일과성 전기억상실증은 최근 확산강조 자기공명영상에서 관찰되는 해마의 허혈성 변화로 가장 많이 보고되어 있으나 그 기전은 아직까지 명확히 밝혀져 있지 않다. 우리는 기억과 학습의 중요한 기능을 하는 것으로 알려진 고삐핵의 일과성허혈발작에 의한 일과성 전기억상실증을 경험하여 보고하는 바이다. 환자는 증상발현 7시간과 96시간 이후에 연속적으로 확산강조 자기공명영상을 시행하였고, 처음 영상에서 나타난 고삐핵의 매우 작은 고신호강도 병변이 이후 영상에서는 관찰되지 않았다. The TGA can be produced by the small and discrete thalamic structure like habenular nucleus that is thought to be related with the cholinergic network for learning and memory in the central nervous system.
