Rapid spontaneous resolution of acute epidural hematoma in an infant:a case report]

Resolution of acute epidural hematoma (AEDH) usually takes several weeks. The authors present an infantile case of AEDH that rapidly decreased within a day and review the literature. A 7-month-old boy fell from a height of approximately one meter and sustained a head injury. On presentation, a skull fracture in the right temporoparietal region was found and a small AEDH was observed on computed tomography (CT) 1 hr after the injury. He was transferred to our institute because of growing AEDH, shown by CT images taken 3 hr after the injury. We decided to treat him conservatively as he did not exhibit any neurological deficits on admission. CT images 24hr after the injury showed significant reduction of the AEDH. There was also an increase in the subcutaneous hematoma. Follow-up CT images did not show enlargement of the AEDH. The patient was discharged with no neurological deficits 3 days after admission. Rapid resolution of the AEDH might have been due to transmigration of the hematoma into the epicranial layer through the fracture gap.
