Bilateral upper-lobe cavities in AIDS, pt PC
Copyright: n/a
Notes:
This patient, thought initially to have pulmonary aspergillosis in AIDS, has bilateral upper-lobe cavities, more marked on the left. He presented with fever, nonproductive cough and dyspnoea. Bronchoscopy yielded Aspergillus fumigatus. He refused therapy and died with progressive disease. He is reported as patient 8 in Denning DW, Follansbee S, Scolaro M, Norris S, Edelstein D, Stevens DA. Pulmonary aspergillosis in AIDS. N Engl J Med 1991; 324: 654-662.
