Image ๐๐ป shows a "HALO SIGN"
The central "nodule" contains the fungal hyphae, the "halo" around represents hemorrhage caused by the angio-invasiveness of the fungus.
This is an EARLY FINDING !!
It is NOT SPECIFIC for IPA, can be seen in GPA etc.

A couple of weeks pass by, you treat with voriconazole and the patients neutropenia has also recovered ๐ช๐ผ
You repeat a CT and see this๐๐ป
This is an "AIR CRESENT SIGN" and signals an improvement in the immune response against aspergillus !!

Another sign to be familiar with is the "HYPODENSE SIGN" shown ๐๐ป
This is seen on the mediastinal window and is quite specific for IFI.

I'm not a radiologist, just a hematologist who frequently deals with these patients.
Would request the radiologists to add more to this short thread ๐งต
