We are back with another #RadiologyRounds for 2024 featuring high-yield imaging findings and teaching points for you to review

In this immunosuppressed patient, you find a reverse halo sign, right pleural effusion and left lower lobe consolidation.

Given the profound neutropenia, the patient was predisposed and mucor was identified on lung tissue biopsy and IV Amphotericin-B was continued.
