Caudal abdominal masses

  • 10 year old male neutered lab, recent history of straining to defaecate, now not eating
  • Plain abdominal xray showed displaced colon with bony material within it, thorax normal
  • Bloods unremarkable
  • Two masses around anus which feel deep seated and have been sampled, pending cytology
  • The liver, spleen, kidneys and adrenals were normal

    • The liver, spleen, kidneys and adrenals were normal
    • There are large (6+ cm) heterogenous and cavitatory sublumbar lymph nodes but also another group of round hypoechoic structures (like a ring of sausages) which lie adjacent to colon and the most caudal one has a cavitatory centre. I don’t think are connected to anything…. are these also lymph nodes? 
    • The bladder is displaced cranially I think the prostate is small, hypoechoic and normal. 
    • I think the distal part of th colon becomes thickened.
    • Can you make out the primary pathology? or could it be the masses around the anus?
    • Any help much appreciated
    • Sorry for long post
