Ranula (Sialocele) in a Cat

This is a very uncommon condition to be found in a cat. In fact after 35 years in veterinary practice this is the first one that I have ever seen. This condition is more commonly seen in dogs, and even then we would not commonly see more than 1-2 in a year.

This is caused by the inflammation of the sublingual and sub-mandibular saliva glands. It is generally associated with trauma, but could also be associated with inflammation or infection. The condition causes a large swelling under the tongue. It is usually only on one side, however it could also be bilateral. This particular cat was presented with the typical very large swelling under the tongue, and inability to swallow due to the swelling and thus an inability to eat. The mouth was wet with excess saliva due to the inability to swallow. The cat had a fever, was lethargic and dehydrated. Antibiotics anti-inflammatories and pain medication was administered, but after 24 hours there was very little improvement. Therefore, after discussion with a medical and surgical specialists, we performed surgery on this patient. The large inflamed and edematous salivary ducts were resected on both sides below the tongue, using a method called marsupialization.

Within hours there was a huge improvement, the patient displayed a significant increase in it’s amount of comfort and was able to begin eating within 12 hours. Shortly thereafter it was in a sufficiently stable condition to be able to bedischarged, and on subsequent follow-up it has continued to do well, is able to eat well, and is returning to full and normal activity.

This was a rare and very interesting case particularly because it was in a cat, and we are all very gratified that the results which turned out so favorably.
