From: Intimal flap detected by three-dimensional curved multiplanar reconstruction image in isolated posterior inferior cerebellar artery dissection: a report of two cases

Fig. 2

Brain magnetic resonance image (MRI), time-of-flight MR angiography (TOF-MRA), and high-resolution vessel wall MRI (HR vw-MRI) in case 2. Diffusion weighted imaging (DWI) shows acute infarction in the left cerebellar hemisphere (a). The left posterior inferior cerebellar artery (PICA) is not seen on TOF-MRA (b). Three-dimensional (3D) oblique sagittal T2 weighted HR vw-MRI reveals intraluminal high signal intensity (white arrow head) and mild dilation of the left proximal PICA (c). Curved MPR image reconstructed from 3D T2 weighted HR vw-MRI shows an intimal flap (white arrow head) in the left proximal PICA and dilation (long arrow) and beaded stenosis (short arrows) in the left proximal PICA (d). Illustration of angiographic images shows an intimal flap and dilation with thrombosis of PICA dissection (e). This figure is illustrated by HGK
