Anti-Phospholipid Antibody Syndrome Presenting with Seizure and Atrial Mass: A Case Report

Antiphospholipid antibody syndrome (APS) has a broad spectrum of thrombotic and non-thrombotic clinical manifestations. Diagnosis requires a set of clinical criteria of thrombosis along with persistently positive anti-phospholipid antibody tests. In this report, we are presenting a case of APS, who is a 38 years old male, presented with complains of seizures and found to have stroke, which on further investigation revealed to have been caused possibly from a left atrial mass. High index of suspicion is required for the diagnosis of APS in young patients, who present with various neurological and cardiovascular manifestations, mostly secondary to thrombosis. APS usually is classified as primary and secondary, respectively, according to the absence or presence of an underlying disease as well as other autoimmune, malignancy, or drug-induced disorders.
