We are presenting a case of a patient diagnosed with Moya\u2010Moya disease and antiphospholipid syndrome (APS) who presented with clinical and laboratory characteristics of catastrophic APS versus TTP. The diagnosis was a challenge because characteristics were overlapping. Nevertheless, a decision to treat the patient for TTP was made with afterward improvement. MMD has been associated with multiple immune disorders; however, only one case of acquired thrombotic thrombocytopenic purpura has been documented in association with this disease. None has been associated with catastrophic antiphospholipid syndrome.
