Calcifications in Cerebral Infarcts: Report of Two Cases

Abstract

Calcification in cerebral infarcts has been reported as an uncommon finding. CT hyperdensity in an infarct can also be due to hemorrhagic transformation and in MRI can be mimicked by cortical laminar necrosis seen as gyriform T1 hyper and T2 hypointensities. Susceptibility-weighted imaging (SWI) with phase image has been reported to differentiate calcification and hemorrhage. We report 2 cases of cerebral infarcts with a review of the literature. The first patient showed early gyriform calcification 10 days after the onset and showed partial resolution of the calcification on follow-up. The second patient showed plaque-like calcification within perisylvian infarct that was confirmed by SWI phase imaging.
