Finally, there is a mucinous type of bronchogenic Ca that can be very cystic-like but I don't remember if it can happen in non-smokers (5 years of 3 ppw in TN is a non-smoker) similar to bronchoalveolar.Baleeirohttps://www.blogger.com/profile/03993066135160692535noreply@blogger.comtag:blogger.com,1999:blog-12660458.post-1118933185953685552005-06-16T10:46:00.000-04:002005-06-16T10:46:00.000-04:00I left out other cystic lesions such as pericardia...I left out other cystic lesions such as pericardial and bronchogenic cysts. Because of resolution and number of cuts (Jeff, I'm not complaining, just making up excuses) I cannot follow the lesion well to see whether it is indeed continuous with some of the other structures around. On the second image (right upper) it seems very close to the bronchus with a thick posterior density suggesting it is pushing away part of the pulm artery to that area. I guess a bronchogenic cyst could explain it all and would be simpler than echinococcosis (though less exciting).Baleeirohttps://www.blogger.com/profile/03993066135160692535noreply@blogger.comtag:blogger.com,1999:blog-12660458.post-1118923798654638082005-06-16T08:09:00.000-04:002005-06-16T08:09:00.000-04:00When CB gives his differential diagnosis first, it...When CB gives his differential diagnosis first, it is hard to think of anything else to add.<BR/>I did see that abnormality on CXR, but thought it was a function of my monitor being lousy.<BR/>I assume you have some sort of tissue analysis to determine the etiology...<BR/>We anxiously await.Mike Lhttps://www.blogger.com/profile/12177750268091750583noreply@blogger.comtag:blogger.com,1999:blog-12660458.post-1118869578697956562005-06-15T17:06:00.000-04:002005-06-15T17:06:00.000-04:00Yeah, not sure what's up with that.

The structure apperas cystic, fluid-filled. Pulmonary sequestration could look like thata. It should not lead to the relative eosinophilia but it seems to be pushing against bronchi leading to partial obstruction and bronchospasm. We don't have lower cuts but it does not look like a diphragmatic hernia.<BR/>I don't see a "double-crescent" but I see a small crescent posteriorly. So, to stay in the realm of esoterica with his travel history I will add hidatid cyst (echinococcosis) to the differential: it would cause the cystic lesion, eosinophilia and local bronchial compression/obstruction.Baleeirohttps://www.blogger.com/profile/03993066135160692535noreply@blogger.com
