Multiple prior studies demonstrate increased bronchovascular markings in the right hemithorax , but on today 's exam these appear to be slightly more consolidative . In addition , there is a new halo - like opacity near the costophrenic angle which is worrisome for possible cavitation . Overall , these findings are concerning for pneumonia and / or aspiration .
