An extremely uncommon complication of ITP: spontaneous rupture of an ovarian follicle cyst and massive intra-abdominal bleeding.

Idiopathic thrombocytopenic purpura usually presents with minor bleeding such as petechia and purpura. Rarely, life-threatening events as intracranial and intra-abdominal bleedings can be seen. We would like to present a rare case diagnosed as idiopathic thrombocytopenic purpura, presenting with abdominal pain and paleness. In this 17-year-old female patient, extensive abdominal sensitivity was revealed on physical examination and massive intra-abdominal hemorrhage secondary to distended ovarian follicle rupture was seen on ultrasonography and abdominal computed tomography. The case was treated successfully with intravenous immunoglobin, thrombocyte suspension, and pulse methylprednisolone.
