Subacute Invasive Pulmonary Aspergillosis

Abstract

Subacute invasive pulmonary aspergillosis (IPA) is an indolent cavitating infectious process which can mimic other chronic lung infections such as tuberculosis. This usually occurs in mildly immunosuppressed individuals and clinically evolves over weeks to months. Radiological presentation is in the form of thick-walled cavity with or without mycetoma, fibrosis, and pleural invasion. Here, a case of subacute IPA in a middle-aged female with rheumatoid arthritis is reported, highlighting a rare radiological appearance.
