A middle-aged man presented with headache, nausea, dizziness, and vision changes for one month duration worsening in the past few days. Imaging revealed multiple embolic infarcts involving the right parietal lobe, left inferior cerebellar hemisphere, and a near-complete blockage of the right internal carotid artery. Additionally, an aortic valve vegetation and a small atrial septal defect was found in a transesophageal echocardiogram. Nonbacterial thrombotic endocarditis was suspected due to negative blood cultures. Elevated autoimmune markers suggested antiphospholipid syndrome. Warfarin and high-dose steroids were started. There was no evidence of atrial fibrillation during a 15-day hospitalization. Follow-up imaging confirmed Libman Sacks endocarditis and ruled out vasculitis. This complex case underscores the importance of interdisciplinary collaboration and thorough investigation in order to achieve a comprehensive diagnosis and effective management of rare conditions like Libman Sacks endocarditis.
