Magnetic resonance imaging angiography in a case of eclampsia.

We experienced a typical case of eclampsia. After the onset of eclampsia, we performed magnetic resonance imaging angiography (MRI angiography) to estimate the function of the cerebral artery. MRI angiography showed that spasm occurred in many cerebral arteries. The spasm was still observed in some arteries 13 day after the onset of eclampsia. Vasospasm of eclampsia was clearly, easily and noninvasively confirmed in this case by MRI angiography. This observation suggests that MRI angiography is very useful and informative for diagnosis and in treatment of eclampsia.
