Abstract

The etiologies of intracranial artery dissection are various, the exogenous as well as inherited connective tissue disorders. We report on a patient who presented with diffuse subarachnoid hemorrhage who had been suffered from essential thrombocythemia. He was diagnosed to multiple dissecting aneurysms of left superior cerebellar artery, left posterior inferior cerebellar artery and right pericallosal artery and treated with endovascular coil embolization.

Figure

  • Fig. 1 Initial brain CT shows subarachnoid hemorrhage and acute hydrocephalus.

  • Fig. 2 A : MRI that shows multiple cerebral infarctions on both cerebellum and body of corpus callosum (white arrows). B : MR angiography. The white arrows indicate fusiform aneurysms on the left SCA and the left PICA. SCA : superior cerebellar artery, PICA : posterior inferior cerebellar artery.

  • Fig. 3 Conventional angiography. The arrows indicate intimal flaps of right pericallosal artery (A), left PICA (B), and left SCA (C). PICA : posterior inferior cerebellar artery, SCA : superior cerebellar artery.

  • Fig. 4 Postoperative conventional angiography. Left SCA is occluded. SCA : superior cerebellar artery.

  • Fig. 5 Postoperative diffusion MRI. Acute cerebellar infarction is detected (arrows).
