Lyla, a gentle 2y female collie, presented with a collection of fluid under the tongue on the right (a sublingual rannula) and a cystic fluid swelling in the upper part of the right neck.
The cystic structure was dissected and removed along with a group of salivary glands in the vicinity which are the usual suspects for these swellings. The cystic structure was full of thick brown gelatinous fluid. The wound was closed over a drain. The mouth was then checked and the sublingual rannula had decompressed, so it was inferred that it had been continuous with the cystic structure that had been dissected from the neck.
We would often “marsupialise” such rannulae to allow them to drain to the mouth, but in this case we decided to not marsupialise the rannula for fear of giving an access route for food into the wound cavity on the neck.
