Internal Medicine and Subspecialties

64 yo M w/ HTN, DM2, OSA admitted with cough, malaise and subjective fevers x 10 days. CXR on admission is the first picture. Second picture is hospital day 6. He had lymphopenia, normal procalcitonin and mild elevations of ferritin and d-dimer. He is COVID positive. O2 says in low 90’s on 2 L, worsened to 4-5 L NC and then improved to low 90’s on room air at rest by time of discharge on hospital day 7. Interesting thing about this case is the discordance between his cxr findings and his symptoms/O2 requirements. I would expect worsening symptoms and O2 requirements given the cxr. He received 5 days of azithromycin and hydroxychloroquine.
