Pathological intracranial extradural hematoma in a 10-year-old child

A nontraumatic spontaneous extradural hematoma, in a fully conscious 10-year-old male child, caused by a solitary eosinophilic granuloma of calvarium presented as a case of localized painful swelling of the head, which rapidly expanded and decreased in size. A plain CT-scan of the head with bone window revealed eroded right parietal bone with subperiosteal debris and extradural hematoma of mixed density. Immediate evacuation of the extradural clot and complete excision of the lesion was performed to prevent the deterioration of the patient and to achieve the histological diagnosis for further management.
