Abstract

This case report presents a rare occurrence of a 14-year-old boy who was initially admitted with convulsion and subsequently diagnosed with acute epidural hematoma (AEDH) on the right side. He was born preterm, with low birth weight, and as the second twin of a dichorionic diamniotic pair. He had a history of surgery at the age of one for a diagnosis of hypospadias and bifid scrotum; however, intraoperative bleeding findings were normal. This AEDH was unrelated to any fractures, and intraoperative findings ruled out bleeding associated with the middle meningeal artery or other fractures. These peculiarities prompted speculation regarding the etiology of the bleeding. During surgery, approximately 1,500 ml of blood was observed. Subsequent postoperative investigations, prolonged low platelet counts indicated a high likelihood of immune thrombocytopenia (ITP). Platelet count was elevated after helicobacter pylori eradication. ITP-associated non-traumatic AEDH is under-reported. Therefore, with or without a history of trauma, hematological diseases, including ITP, should be considered as a course of AEDH.
