Had a recent case:

• 6yo MN Ferret
• 3 days ADR, then acutely ill, icteric, bloody diarrhea
• b/w pending
• US revealed : GB sludge filled, thick walls; dilated cystic & CBD.
• Dilated CBD to papilla
• Other findings: ascites, hypoechoic lymph nodes; right adrenal mass

See below for stills/video of duopap & GB.  Has anyone seen this in a ferret?  If so, how common is it & has a bile obstruction been successfully treated?
