Extradural Hematoma Following Frontal Sinusitis: Report of a Case and Review of the Literature

A review of spontaneous intracranial extradural hematoma in sickle-cell disease

“…Non-traumatic intracranial extradural hematomas (EDHs) are rare, and reports have associated their etiology with infections [3,9,14,20,25,29,31,33,37], coagulation disorders [39,43], hemodialysis, cardiac surgery [28,38], neoplasms [6,15,18,22,41], and vascular malformations [35]. The first case report of a spontaneous EDH was described in 1951 [37].…”

Spontaneous intracranial extradural hematoma: Case report and literature review

“…Till date including our case only 19 cases [ Table 1] were documented in the literature. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] Of the 18 patients documented in the literature, adjacent cranio-facial infections were the causes in 14 patients: Paranasal infection in nine (3,5,(8)(9)(10)(11)(12)(13), chronic otitis in four (1,2,4,6), and furuncle on the ala nasi in one (1). The proposed mechanism was intracranial spread of the infection from the craniofacial site and the vasculitis associated with the infection, bleeding from the rupture of vasculitic vessel and subsequent expansion.…”

“…Till date there are 18 such documented cases in the literature. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] The first documentation of spontaneous EDH was by Schneider and Hegarty in 1951. [1] We report spontaneous EDH in patient with chronic kidney disease (CKD) on intermittent hemodyalisis.…”

Hematoma epidural espontâneo: relato de dois casos

“…Em relação às infecções pericranianas, os casos apresentados na literatura estão associados a sinusite frontal 7,8,11 ou otite média 5,6,9,10 . Nesta categoria dois mecanismos são propostos para explicar a ocorrência do HED.…”

“…Cerca de 83 a 95% dos casos estão associados a fraturas de crânio [2][3][4][5] ; porém, quando não há história ou sinais de traumatismo e na ausência de fraturas de crânio, pode-se dizer que o HED ocorreu espontaneamente 5 . Alguns casos de HED espontâneo têm sido relatados, associados a doenças infecciosas (sinusites e otite média aguda) [5][6][7][8][9][10][11] , malformações vasculares da dura-máter 5,12,13 , distúrbios da coagulação 14,15 e metástases na calota craniana 16 . Neste artigo apresentamos dois casos de HED espontâneo, um deles associado a distúrbios da coagulação e o outro a pansinusite.…”
