Chronic infarction left lentiform nucleus with extension into the adjacent frontal corona radiata. Other smaller chronic infarcts are also present.
Case Discussion
The left atrial mass was resected and proven to be a thrombus. This thrombus was the presumed source of emboli that caused this patient's stroke. The thrombus was initially discovered on echocardiography and confirmed on CT. The patient did undergo head CT and brain MRI at presentation (not shown) which confirmed an acute ischemic stroke, shown in the chronic stage on the head CT above.
