I have a Lesser Pastel (really nice looking) named Bananas (because his alien heads look like banana slices) who has regurged strangely. The first regurge was (from memory) 20 Nov 2014. We waited and fed again and all seemed fine, then another strange regurge in December. The regurges were strange because they did not smell and were covered in a thin layer of mucus. I have only had one actual regurge from one of my females, and it smelled to high Heaven. These were clearly different (like they never made it to the stomach)

So we waited again and then fed smaller prey. All good, he ate fine. This continued (him eating fine) until 25 July 2015 and he regurged a 39 gram rat. He can take 70 gram rats, no problem (or he should be able to). Ok, something is up! So I did a little homework on local vets and due to an completely inaccurate care sheet for snakes I excluded one of the two remaining from my search and made an appointment.

The vet was surprised (I took my log book with weights and feed records) at my husbandry and knowledge. So excluding impaction and illness the next step was x-rays. Which I hope to get copies of so I can post them. Unfortunately the x-rays showed a mass, most of the way down the esophagus but before the stomach. The mass comes from the side of the body and pushed on the esophagus.

The vet wants to have the x-rays reviewed by some peers. Then do a micro needle biopsy of the tissue. She used a term, an acronym, NAG, to describe the three (most likely) things it could be. Anybody know this term and can break it down for me? I tried a search but didn't get good results. Basically, cancer, infection, or malformed tissue, is my understanding.

I'm betting we have an infection and I think its growing. Thus the need for smaller and smaller prey (not clearly stated above).

Hopefully I haven't just seen that I'm going loose this male. I also hope I can post the x-rays, the mass is clearly visible and shows the need to have a good vet.
