title: Continual intracavitary administration of amphotericin B as an adjunct in the treatment of aspergillus brain abscess: case report and review of the literature.
abstract: Aspergillus brain abscess is often a fatal disease, regardless of the mode of therapy. Most often seen in the compromised host, it is notoriously refractory to systemic antifungal agents and intrathecal antimycotics. Even with radical surgical debridement, only 13 patients, including the present case, have survived longer than 3 months after being treated for aspergillus brain abscess or granuloma. Studies have shown poor penetration of amphotericin B into the brain and cerebrospinal fluid. One way to achieve therapeutic levels of the agent near the abscess is through the direct introduction of the agent into the abscess site via an indwelling catheter. In the present case, a woman with an aspergillus abscess of the left temporal lobe was treated by a combination of systemic agents, radical debridement, and local therapy, resulting in a cure with a follow-up of 6 years. This is the first reported instance of the use of long-term, local antifungal therapy delivered to the area of the abscess cavity, using a closed reservoir system, and this patient is only the second renal transplant patient reported to have survived aspergillus brain abscess. This form of treatment produced no untoward long-term side effects or neurological sequelae. Local irrigation with antifungal agents should be considered in conjunction with systemic antifungal drugs and drainage and/or debridement in cases of fungal intracerebral aspergilloma. This technique may also prove useful with other fungal brain lesions.
