Title: [abstract] MALIGNANT EXTERNAL OTITIS CAUSED BY PSEUDOALLESCHERIA BOYDII TREATED WITH HYPERBARIC OXYGEN.

Abstract: A 62-year old diabetic was in 1986 treated for a mastoiditis of the left ear. In January 1988 he returned with pain and secretion from the ear. combined with paralysis of the Vth and IXth cranial nerves. CAT-scan was normal. Surgical exploration of the left ear showed the mastoid cavity to be filled with granulation tissue containing microabscesses. A scintigram revealed increased utake of Tc99 in the bony part of the external auditory canal of the left ear. Despite different antibacterial antibiotics were tried and repeated cultures from the ears were negative, the condition deteriorated. In September a new Tc99-scan revealed increased isoptope uptake in the right temporal bone and a CAT-scan confirmed an apicitis. Analysis of CSF showed a severe barrier damage and leukocytosis. Cultures from the external auditory canals yielded growth of P. boydii. Oral intraconazole was given 200 mg daily for one year. Hyperbaric oxygen treatment was started and conducted at 2.4 ATA. 90 minutes daily for 60 days. A Tc99 scan after HBO was normal. Repeated cultures from the cars have been negative. A NMR-scan revealed no signs of infectious spread in the soft tissues of the face and neck. Repeated CSF-tests were normalised by March 1989. The patient has no signs of cranial nerve engagement. Conclusion: A long-lasting external otitis deteriorated until microbial cultures yielded growth of Pseudoallescheria boydii. Hyperbaric oxygenation was used as an adjuvant therapy to antifungal therapy and surgery. Normalization of techentium bone scans were demonstrated after HBO-therapy. The patient is without evidence of disease. one and a half years after diagnosis.
