- FIG 1.
COVID-19-associated left MCA vascular territory acute infarcts in a pediatric patient. Axial diffusion (A), ADC map (B), and FLAIR (C) images demonstrate foci of restricted diffusion (blue arrows) and cytotoxic edema (yellow arrow) within the left middle cerebral artery vascular territory, consistent with acute infarcts. Anterior projection from a TOF-MRA of the head (D) demonstrates a focal segment of moderate stenosis within the left M1 middle cerebral artery (red arrow).
- FIG 2.
Vessel wall enhancement within the M1 left MCA. Vessel wall imaging targeted to the left middle cerebral artery with axial pre- (A) and postcontrast (D) 3D T1 volume isotropic turbo spin-echo acquisition sequences, with reformatted coronal images; B and E, respectively). Pre- (C) and postcontrast (F) reformatted sagittal images en face to the M1 left middle cerebral artery at the level of the blue and yellow arrows, respectively. There is wall thickening (blue arrow) and marked concentric contrast enhancement of the M1 left middle cerebral artery at the segment of stenosis (yellow arrows). The imaging findings, in conjunction with the clinical history, were consistent with FCA-inflammatory type.
