Abstract
Syringobulbia is a rare neurological disorder characterized by a fluid-filled cavity in the brainstem. In this study, clinical signs, features on magnetic resonance imaging (MRI), and the diseases present concurrently with syringobulbia were investigated in 33 small breed dogs. Most dogs (97%) had concurrent syringomyelia, and some dogs (24%) presented with vestibular or cranial nerve symptoms associated with the medulla oblongata. MRIs revealed slit-like, bulbous, and vertical linear shapes of the cavities on T2-weighted hyperintense and T1-weighted hypointense signals similar to the cerebrospinal fluid. Chiari-like malformations were identified in all dogs. This study highlights the association of syringobulbia with syringomyelia and Chiari-like malformations in small breed dogs with or without brainstem-associated clinical signs.
