A 57-yr-old man with a chronic lung cavity presumed to be related to ankylosing spondylitis and/or old cavitary tuberculosis presented with hemoptysis and rapidly developed lower extremity paresis and hypoesthesia. On chest radiograph he had a left upper lobe lesion suggestive of aspergilloma combined with a large left empyema with bronchopleural fistula. Serologic analysis demonstrated precipitins and very high titer IgG antibodies to Aspergillus fumigatus antigens. Decompressive laminectomy from T1 to T5 was performed, with drainage of A. fumigatus culture-positive material from an epidural abscess compressing the spinal cord. Chest drainage was required for control of the empyema. With a total course of 3 g of intravenously administered amphotericin B, rehabilitative therapy, and chronic empyema drainage, he is now at home and ambulatory with assistance. He is also being followed by regular serum assays of IgG antibodies to Aspergillus proteins. We report the case of an apparent long-term survivor of a formerly lethal and/or nonreversible paraplegic condition. The critical factors compared with previous cases with a poor outcome would appear to be prompt neurosurgical intervention, restoration of a normal number of T-cells, effective long-term chest drainage, and high dose amphotericin treatment.
