Pregnancy is a recognized risk factor for aneurysmal subarachnoid hemorrhage (SAH). Headache is very frequent in normal pregnancy and it is a common sign shared between several intracranial diseases. We present a case series of 10 women in the third trimester of pregnancy admitted to our intensive care unit (ICU) with neurological signs and symptoms. 4 of these patients were diagnosed with SAH. Data in this study suggest that a timely diagnosis and an appropriate treatment is crucial for mother and baby.
