Atypical presentations of thrombotic thrombocytopenic purpura in middle-aged women with recurrent cerebral macrovascular thrombosis: a case report

Dear Editor, In the current clinical practice, minimal criteria to define thrombotic thrombocytopenic purpura (TTP) are the presence of signs of microangiopathic haemolytic anaemia and low platelet (PLT) count [1].
