Miliary nodules: An unusual presentation of allergic bronchopulmonary aspergillosis.

[allergic bronchopulmonary aspergillosis]

Allergic bronchopulmonary aspergillosis (ABPA ) is an immune-mediated inflammatory disease caused by hypersensitivity to Aspergillus fumigatus . A wide spectrum of plain radiographic appearances has been described in ABPA , though none are pathognomonic of ABPA . The common radiological abnormalities encountered are fleeting pulmonary opacities , bronchiectasis , and mucoid impaction . Uncommon radiological findings encountered in ABPA include pulmonary masses , perihilar opacities simulating hilar adenopathy , and pleural effusions . However , miliary nodules as a radiological presentation of ABPA are very rare and only one case has been reported in literature . It is often misdiagnosed and mismanaged as tuberculosis ; thus , the clinician should be vigilant enough to diagnose this very rare entity .
