Case Of the Week (COW) 01 May 2016
ACUTE INFARCT WITH LUXURY PERFUSION
Findings
T2/FLAIR hyperintensity noted in the left corona radiata and ganglio-capsular region, which shows diffusion restriction and low ADC, no evidence of blooming noted. On contrast the areas shows significant enhancement noted. ASL shows increased perfusion in left lentiform nucleus.
Discussion
Typical case of infarct gangliocapsular region. T2 /FLAIR hyperintensity Restricted diffusion Low adc signal Enhancement on contrast increased perfusion on ASL images. CAUSES OF INCREASED PERFUSION IN INFARCTS: Luxury perfusion Reperfusion Spontaneous recanalisation Thrombolytic induced recanalisation LUXURY PERFUSION is considered as a reason for the increased perfusion in this case.This is due to local autoregulatory dysfunction mechanism in case of stroke. Sluggish transit of intravascular arterial spins may account for focal high ASL signal intensity.
