Session: Incidental Lacunes on Brain Imaging: How to Manage Them
Moderators: Dr. Christopher Lewandowski, Dr. Edip Gurol
Panelists: Dr. Hugo Aparicio, Dr. Eric Smith, Dr. Myriam Fornage, Dr. Jose Gutierrez
This invited symposium overviewed incidentally discovered lacunar infarcts on brain imaging. Dr. Aparicio from Boston University began by discussing prevalence and risk factors for incidental lacunar infarcts. Based on data from the Rotterdam Scan Study and Cardiovascular Health Study, “covert” brain infarcts (CBI) are not uncommon, making up about 1 in 10 in late middle age and 1 in 4 in the elderly, with an overall prevalence of 8-28% amongst predominantly non-Hispanic White and Asian study populations. Lacunar infarcts make up the majority of CBIs (83%) and share risk factors for stroke, especially age and hypertension; however, CBIs possibly have as high as 5-fold increased incidence when compared to stroke.
