Chronic intradiploic hematoma in patients with coagulopathy.

Intradiploic hematomas occur rarely. They have been reported in patients with and without coagulation disorders. The presentation of intradiploic hematomas varies depending on their location and the severity of the coagulopathy. We describe a patient with a huge hemicranial chronic intradiploic hematoma. Surgery involved opening the thinned outer table and evacuation of a jelly-like material and an organized clot, leaving behind the inner table. The rarity of this disease, possible pathogenesis and related surgical aspects are discussed.
