Abstract
- We present the case of a 28-year-old pregnant woman with subarachnoid hemorrhage who was initially unable to undergo a CT scan and exhibited interestingly high signal intensities only on T2-weighted MRI without any signal change on fluid attenuated inversion recovery and gradient-echo imaging. These findings could be explained by a combination of factors that increase the signal intensity with elevations in the concentrations of protein and oxyhemoglobin due to massive bleeding and with the decreased fluid void signal inferred by the presence of hydrocephalus.
