A Rare Cause of Pulmonary Embolism and Seizure in a Young Man: Antiphospholipid Syndrome.

Pulmonary embolism (PE) is a complication of underlying vascular thrombosis. The causes of PE are multi-factorial, and patients with PE present with various symptoms. We herein have presented the case of a 21-year-old man who initially developed palpitation, dyspnea, and seizure. Computed tomography of the chest ultimately indicated PE, and antiphospholipid syndrome (APS) was diagnosed with clinical thrombosis events and series presence of antiphospholipid antibodies. APS commonly causes vascular thrombosis within the vascular tree; however, nonthrombotic manifestations, such as seizure, may also occur. Clinicians should be aware of such non-thrombotic manifestations of APS to avoid misdiagnosis and inappropriate management.
