ITP manifests as a bleeding tendency, easy bruising (purpura), or extravasation of blood from capillaries into skin and mucous membranes (petechiae). Although most cases of acute ITP, particularly in children, are mild and self-limited, intracranial hemorrhage may occur when the platelet count drops below 10 × 109/L (< 10 × 103/µL);  [1]   this occurs in 0.5-1% of children, and half of these cases are fatal.  [2]
