Summary

A cat with weight loss and jaundice had ectopic liver tissue in its pericardial sac. This rare condition, confirmed by necropsy, caused significant hepatic disease and heart abnormalities.

Area of Science:

  • Veterinary Medicine
  • Comparative Pathology
  • Cardiology

Background:

  • Ectopic tissue can occur in various locations, but hepatic tissue within the pericardial sac is exceptionally rare in domestic animals.
  • Hepatic disease in cats can manifest with diverse clinical signs, including weight loss, jaundice, and gastrointestinal disturbances.

Purpose of the Study:

  • To describe a unique case of ectopic hepatic tissue within the pericardial sac of a domestic short-haired cat.
  • To detail the clinical, diagnostic, and post-mortem findings associated with this rare condition.

Main Methods:

  • Clinical examination, laboratory diagnostics (blood work), radiography, and ultrasonography were performed.
  • Post-mortem examination (necropsy) was conducted to determine the definitive cause of the clinical signs.

Main Results:

  • The cat presented with emaciation, jaundice, enlarged liver, ascites, and an enlarged heart.
  • Ultrasonography revealed fluid and tissue within the pericardial sac.
  • Necropsy confirmed ectopic hepatic tissue in the pericardial sac, connected to the liver, with both tissues showing chronic active pericholangitis and nodular hyperplasia.

Conclusions:

  • Ectopic hepatic tissue within the pericardial sac is a rare but significant finding in cats.
  • This condition can mimic other cardiac and hepatic diseases, necessitating thorough diagnostic investigation.
  • The presence of ectopic liver tissue can lead to severe hepatic pathology and secondary complications.
