Eosinophilic Granuloma of Skull with Fluid Level and Epidural Hematoma: A Case Report and Review of the Literature.

Intracranial Langerhans cell histiocytosis commonly presents as skull lesions in children. An intratumoral cyst with fluid level and epidural hematoma occurring with eosinophilic granuloma is very rare. We report a 15-year-old boy who presented with a spontaneous epidural hematoma which was the result of a temporal eosinophilic granuloma. Multiple explanations for epidural hematoma in such cases have been discussed. Intratumoral hemorrhage followed by cyst formation and rupture may explain the pathophysiology of epidural hemorrhage formation.
