Learning objectives To differentiate between contrast enhancement of luxury perfusion and the appearance of some types of brain tumors. Also, to differentiate luxury perfusion from cortical laminal necrosis.
Read more Background Luxury perfusion is a vascular response to ischemia that is characterized by increased perfusion to the infarcted area in order to meet the local metabolic requirements, through dilatation of multiple vascular channels, particularly venous channels.This is observed in the infarcted area of the brain 24-48 hours after ictus, in both treated and untreated cases, usually in the subacute phase, but has been documented as early as within the first 24 hours. The peak occurs in the second and third week,...
Read more Findings and procedure details On a contrasted CT scan and MRI scan,  this phenomenon of luxury perfusion is perceived as an area of enhancement at the margin of the infarct, with a gyriform pattern or in the deep parenchyma. This can have a confused and bizarre appearance, mimicking tumors, and be misinterpreted as contrast uptake from a malignant tumor, especially so if prior knowledge of the infarct is not known and in younger patients.Primary and secondary brain tumors can imitate luxury perfusion because of...
Read more Conclusion Imaging is crucial in ensuring that malignant tumors are identified and distinguished from luxury perfusion, as this has a substantial impact on therapy for tumors requiring removal.
