[Productive aspergilloma on the inner wall of a cavity].

Fungus ball type pulmonary aspergilloma is easily recognizable on chest X-ray. This is a report on "productive aspergilloma on the inner wall of a cavity" (PAIC), named from our clinical experience in 1980, which grew to form aspergillus strata on partial or overall inner walls of the cavity. Our 5 cases with this type supported the existence of this type and revealed an 18% incidence in patients with pulmonary aspergilloma, characteristic clinical features and immunological reactions, thus pointing to the necessity of early diagnosis and treatment for this type of aspergilloma. The species of aspergillus cultured from the patients with this type of disease was Aspergillus fumigatus.
