Epidemiology
According to the location of the abscess, the incidence of the condition will be different:
Intracranial Epidural Abscess
The most rare type of epidural abscess, it accounts for only 1 in 10 cases of the disease. Despite this fact, it is the 3rd most common focal intracranial infection, following brain abscess and subdural empyema. Before the arrival of antibiotics, the most common cause were sinusitis, otitis and mastoiditis. Today it happens most often following neurosurgical procedures and in IV drug users. The cases not related to iatrogenesis, occur more commonly in adolescent males, since they are more prone to sinusitis and its complications. This incidence is due to the increase of vascularity of the diploic system and development of frontal sinus between the 7th and 20th year of age, which contributes to the spread of the infection, since the sinus mucosa communicates with the marrow spaces of the frontal bone, as well as with the veins of the dura mater. [1] According to a study of Gallagher et al 15 out of 176 patients with sinusitis, developed some kind of intracranial suppuration as a complication. Of these, 23% developed epidural abscess. [2]
Spinal Epidural Abscess
The most common type of epidural abscess, it can occur in patients of all ages, however is more common in those with more than 50 years of age, with studies showing a male predominance of the disease. [3]
