Another example of the course of arteriopathy in TCA. Conventional contrast angiography performed at 2 weeks (A) and 7 months (B) after stroke in a 7-year-old boy. (A) There is a long segmental irregular stenosis of the M1 of the MCA with beading at initial angiography. (B) Transient worsening of the disease with severe focal stenosis of the proximal M1 of the MCA (left arrow) and a long segmental stenosis of the M1 (right arrow). The beading, typical for the acute phase of TCA, is less prominent. Repeated angiography 22 months after stroke was identical, proving stabilization of arterial abnormalities (not shown).
