We reported a case of subacute @entity510 with watery clear cerebrospinal fluid. Emergent magnetic resonance image was useful not only for diagnosis by fluid attenuated inversion recovery image but also for evaluation of @entity2806 and @entity2553 by magnetic resonance angiography, diffusion weighted image and perfusion weighted image. A 50-year-old @entity1 presented disturbance of @entity1662 and @entity4653 . Neither computed tomographic scan nor cerebrospinal fluid study could diagnose @entity510 clearly. However, emergent fluid attenuated inversion recovery image showed the show @entity510 as high signal intensity. Diffusion weighted image showed multiple, round hypersignals both in the white and gray matter. In the area with diffusion hypersignal, the apparent diffusion coefficient value was 0.57 x 10(3) @entity202 /sec. Perfusion weighted image showed normal cerebral blood volume but prolonged mean transit time in the territory of the right middle cerebral artery. Magnetic resonance angiography revealed an @entity439 at the anterior communicating artery and severe @entity2553 on the bilateral anterior cerebral artery, the right middle cerebral artery. Thus we are able to diagnose @entity510 due to a @entity6151 communicating @entity438 . The hyperintensity of the diffusion weighted image and the fluid attenuated inversion recovery image was caused by @entity2806 from @entity2553 . After conservative therapy during the period of @entity2553 , successful surgical clipping was performed with full clinical recovery.
