Do NOT use CT for screening!. 50% of early cases have no findings on CT.
Findings include peripheral and peribronchovascular GGOs, basilar predominant OP pattern.

Usefulness of delayed phase acquisition (bottom) for exclusion of left atrial appendage tip thrombus on LAA and Pulm Vein studies. Arterial phase (top) w incomplete opacification and pseudothrombus.
🚨Here's your quarterly reminder to pay attention to the myocardium non-cardiac CT! 🫀Small apical lateral wall embolic infarction with pap muscle involvement.
👀Splenic infarct also present.

for catching this one!
🫀Cor Triatriatum:
🔸fibromuscular membrane dividing the left atrium into a pulm venous and true atrial chambers.
🔸Failure of incorporation of the common pulm vein.
🔸Associated w PAPVR, ASD, BAV, etc
🔸Adults typically asymptomatic (wide communication)

Here's a wonderful case spanning multiple subspecialties. And yes, pimping again for this one.
Patient in their 60s with cough, chest pain and dyspnea for one month before the initial chest CT below.
What are your thoughts?

🫁 This, as many replied, is a case of Carney triad. Multiple pulmonary chondromas, gastrectomy for GIST, and a mediastinal paraganglioma (round, enhancing and FDG-avid periaortic mass). Some chondromas can be FDG avid.
