Frontal portable chest x-ray. There is low to moderate lung expansion with mild elevation of the right hemidiaphragm. There is a small to moderate right pleural effusion and patchy airspace disease in the mid and lower right lung and left lung base, increased from 7/13/2022. Additional confluent masslike density in the right perihilar region is present, increased from the prior exam. 

There is no interval imaging since chest x-ray 7/13/2022. If there are signs and symptoms of infection, then the findings may represent a residual progressive and/or recurrent inflammatory/infectious process, e.g. pneumonia/bronchopneumonia, and recommend appropriate therapy and short interval follow-up imaging to confirm resolution. If, however, there are no signs or symptoms of infection, a nonspecific right perihilar mass/masslike lesion in with nonspecific bilateral airspace disease, right greater than left, and right pleural effusion should be considered and CT correlation at this time the advised. 

Summarize what's written about masslike lesions in the above radiographic transcript. Provide the entire answer in JSON format.
