Abstract
Thrombotic thrombocytopenic purpura (TTP) is a rare but life-threatening hematologic disorder characterized by thrombocytopenia, microangiopathic hemolytic anemia, neurologic symptoms, renal impairment, and fever. The etiology of TTP often involves a severe deficiency in ADAMTS13 activity, resulting in the accumulation of ultra-large von Willebrand factor multimers and subsequent microvascular thrombosis. Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can affect multiple organ systems, and although the initial presentation of SLE with TTP is rare, it necessitates a comprehensive diagnostic and therapeutic approach. We present a case of a 27-year-old male with no significant past medical history who developed altered mental status, headache, and right-sided numbness, leading to the diagnosis of TTP and subsequent detection of SLE.
