As breeders, your concern for the possible presence, severity, duration, management an heritability of both Chiari-Like Malformation and Syringomyelia will likely give rise to questions that we have endeavored to anticipate and answer in a helpful and instructive manner in the appropriate areas on this site. We encourage you to visit the topics explored in the menus under each subject.

Definition

What is chiari-like malformation (also known as COMS)? Chiari-like malformation (CLM), formerly known as Caudal Occipital Malformation Syndrome (COMS) is a condition in which part of the brain, the cerebellum, descends out of the skull through the opening at its base, called the foramen magnum, crowding the spinal cord.

Clinical Signs

The hallmarks of this disorder are pain and abnormal sensations like itchiness. We can usually tell if a dog is in pain with CLM/SM. An affected dog will often cry out and adopt a “nose down” position when his/her neck is hurting. Although neck pain is very common with this disorder, we have also seen a large number of dogs who exhibited back pain as well. Dogs with CLM/SM often appear to have increased sensitivity to being touched.

Diagnosis

Before the advent of MRI, the diagnosis of CLM and SM were commonly confused with that of intervertebral disk disease, allergic dermatologic disorders, epilepsy, and ear infections. Once Chiari malformation was reported in human patients, preliminary research provided the foundation to identify its analogue in the animal population.

MR Imaging

MRI
There are a wide range of improvements in MRI technology since the first published MR image was presented in 1973. Many of the improvements, however, can be attributed to two aspects of MR imaging, increasing field strength and parallel imaging techniques. At The Canine Chiari Institute, we are equipped with the only 3 Tesla MRI in the world dedicated to veterinary imaging and recognize the benefits of better resolution, faster imaging requiring less anesthesia time, and CSF flow studies with each patient.

Treatment

Does my dog need treatment?
The answer to this question is multifactorial. The age of the dog tends to be a very important consideration in many instances. Young dogs with clinical signs should be considered for surgical treatment, while older dogs with minimal to no clinical signs could be managed medically or surgically. The severity of CLM/SM plays a role in this decision.

After Treatment

What can I expect after surgery?

Cranioplasty with FMD appears to be well tolerated in dogs with CLM/SM with very few complications being noted. Most dogs are hospitalized for 4-5 days depending on their clinical condition. Because cerebellar decompression is immediate, intracranial clinical signs can be expected to resolve faster than those related to SM. The reduction in syrinx size is paramount to clinical recovery.
