Pneumonia / Lung Infections

Review the different ways lung infections can present on imaging, a practical method for categorizing lung infections, and what the role of medical imaging is in their diagnosis.

thank you for posting this educational video. I’m a community Intensivist. Appreciate you sharing the knowledge Make me feel I’m in an academic center and can continue my lifelong learning

[@DanielC-ck2ds]

Thank you so much! This is literally the best video on yt on pneumonia. Please keep up the good work!

[@nezarmohamed5850]

Perfect and excellent thanks

My Husband has stage 4 cancer he has fungal infection in the Lungs 17 weeks he on antibiotics How long does it take to complete he wants to get back on the chemotherapy

Prayers 🙏 for your husband

can you explain halo and reverse halo signs in fungal infection

[@radiologyframeworks]

Sure thing! Halo sign = solid nodule or mass surrounded by a zone of ground-glass opacity (i.e. solid opacity centrally, ground-glass peripherally). Reverse halo sign = ground-glass with consolidation along its margins (ground-glass centrally, solid opacity peripherally). Halo sign can occur with invasive aspergillosis, endemic fungal infections, and mucormycosis. However, halo sign is not specific for fungal infection and can occur with many other disorders, e.g. septic pulmonary emboli, nocardia, primary lung cancer, GPA, and lung mets from melanoma, choriocarcinoma, and angiosarcoma just to name a few. Although we tend to think of organizing pneumonia, slowly resolving lung infections, and pulmonary infarcts first when we encounter reversed halo sign, one fungal infection in particular comes to mind too - mucormycosis. I'll share some images of one such case in the "Community" tab for this channel.
