Objective:
To clarify the frequency of imaging findings similar to mycobacterial infection and the characteristics of comorbid pulmonary non-tuberculosis mycobacteriosis in the patients with allergic bronchopulmonary mycosis (ABPM).
Subjects And Methods:
Patients treated with ABPM at our hospital in the past 8 years were extracted from medical records, and 32 patients who met the clinical diagnostic criteria were retrospectively examined.
Results:
The median age was 62.5 years (range 24-79 years), and 21 patients were female. Twenty-two had asthma, and four had old tuberculosis. CT findings showed central bronchiectasis in 29 cases, centrilobular nodulars in 26 cases, and mediastinal lymphadenopathy in 3 cases. Pulmonary M. avium complex (pMAC) disease was complicated in 4 cases. Regarding the time of diagnosis of pMAC disease, 2 cases were diagnosed concurrently with ABPM, 1 case was before ABPM diagnosis, and 1 case was during ABPM treatment. The main lesion of ABPM occurred in a different site from that of pMAC disease.
Conclusions:
ABPM and mycobacterial infection not only have similar imaging findings, but they can also occur synchronously and metachronously. Complication of ABPM and pMAC disease may be due to risk factors common to both diseases, such as the patient's constitution and living environment.
