Abstract
BackgroundVolume isotropic turbo spin-echo acquisition (VISTA) is a new method similar to the 3D black-blood imaging method that enables visualization of a intramural hematoma. T1-VISTA has recently been applied in the diagnosis of intracranial arterial dissection. However, the identification of an intramural hematoma in posterior inferior cerebellar dissection (PICA-D) by T1-VISTA has only rarely been reported.Case presentationWe herein report two patients who suffered from PICA-D complicated with ischemic stroke. Initial magnetic resonance arteriography was not informative, however, T1-VISTA depicted high-intensity signal areas suggesting an intramural hematoma of PICA-D in both cases. The high-intensity signal areas gradually reduced and finally disappeared at 4 months and 5 months after the onset, respectively.ConclusionOur cases demonstrate that T1-VISTA was able to assist in the diagnosis and follow-up of PICA-D.

Volume isotropic turbo spin-echo acquisition (VISTA) is a new method similar to the 3D black-blood imaging method that enables visualization of a intramural hematoma
While vertebral artery dissection (VA-D) is the most frequent among intracranial arterial dissections complicated with ischemic stroke, posterior inferior cerebellar dissection (PICA-D) is rare [2]
One paper previously reported the identification of an intramural hematoma of PICAD using T1-VISTA [3], whereas no study has been available for its follow-up

T1-VISTA showed a slight expansion of the high-intensity area at 3 days after admission, but still no lesions on T1 images.
