[Brain abscess secondary to rhinosinusitis. Therapeutical modalities. Exposition of one case].
Brain abscess (BA) as complication of sinusitis represent around 3% of the cases. Other suppurative intracraneal complications such as epidural abscess, subdural empyema and meningitis are more common than BA. The frontal and ethmoid sinuses form an integral part of anterior and to a lesser extent middle skull base to which the dura is intimately related. Thrombophlebitis of veins associated with paranasal sinuses is considered to be the main route of intracraneal spread of infection. However, osteitis is an uncommon mechanism that typically involves frontal sinus. Chronic sinusitis more than fulminant course of acute sinusitis is often responsible for BA. Epidemiology of BA has changed with the increasing incidence of this infection in inmunocompromised patient and the decreasing incidence related to sinus infection. Mortality rate of BA were around 35-55% before CT scan era and with surgical excision as the rule of surgical treatment.
