mystery chest x-ray competition

I'm now settling into my job at HTD (Hospital for Tropical Diseases), though unfortunately I've had to start by going straight into a week of nights. It isn't too bad so far, and there have been some pretty interesting admissions.

I'm currently a bit mystified by one guy who came in today, so I thought I'd make this into a kind of Tropical Quiz question - hopefully someone will read this and e-mail me the diagnosis...

So: 22yr old caucasian man, recently returned from 2 months in Uganda. He suffered with malaria while out there, treated successfully with quinine. Also self-medicated with praziquantel for possible schistosomasis after swimming in high-risk water. No sexual activity whilst in Uganda. On return to UK, he has been having some vague fevers, but otherwise not too bad - not coughing or losing weight. He's normally fit+well.

At HTD, he has been found to have an eosinophilia (0.8) and also this bizarre chest x-ray:


Alternative settings to show bizarre lesions...



So not actually sure what he may have. My top ideas so far are
1. Schistosomiasis - ?Loefflers lungs appearance?
2. some other wormy-type thing eg Paragonamiasis, strongyloides
3. TB
4. ?? Lymph nodes

I hope some clever doctors out there can see these x-rays and make a spot diagnosis... Prize of a special mention on my blog for anyone who seends a sensible suggestion !
I'm just going to wait for all the tests to start giving an idea.
