In a follow-up CT scan performed 6 days later, the infarcted area is now isodense and barely distinguishable from surrounding normal brain tissue.
Case Discussion
While acute cerebral infarcts are hypodense lesions, after a week or so, the fogging phenomenon often occurs. This refers to an evolution in density of the lesion from hypodense to isodense to surrounding brain parenchyma.
