A unique case of brain abscess treated with intracavitary amphotericin.

Here we present a case of a poorly controlled diabetic who developed extensive rhinocerebral mucormycosis. Systemic and intrathecal amphotericin were not able to improve his life threatening infection. Therefore, salvage therapy with intracavitary amphotericin B deoxycholate was used to instill antifungal therapy directly into the patient's brain abscess. For proper dosing of intracavitary amphotericin B deoxycholate, we devised a formula which can be theoretically applied for all intracavitary therapies. Unfortunately, the patient's family withdrew care 6 days after starting intracavitary amphotericin and efficacy of this therapy could not be evaluated.
