Intracranial mycotic infections in neurosurgical practice.
Intracranial mycotic infections requiring neurosurgical intervention are being diagnosed more frequently. This study is a review of 17 cases of intracranial mycotic infections that were treated in a neurosurgical unit in Saudi Arabia over an 8-year period. A primary focus of infection was identified in 41% of patients while 18% of patients had a predisposing factor. Forty-seven percent of patients presented with a brain abscess (solitary 29%, multiple 18%) while 35% had a granuloma. 18% meningitis and ventriculitis and 12% hydrocephalus. The Aspergillus species and Ramichloridium machenziei were the commonest pathogens. Following the appropriate surgical and antimicrobial treatment, the mortality rate was 41% and there was evidence of residual disease at follow-up in 18%. The reason for a fatal outcome was failure to consider a fungal aetiology and to obtain a tissue diagnosis early-because of late referral (2 cases), as well as failure to respond to antimycotic therapy (4 cases) and rupture of the internal carotid artery due to Aspergillus arteritis (one case). It is concluded that an early tissue diagnosis is crucial in the management of intracranial mycotic infection so that the appropriate surgical and antimycotic treatment can be started early.
