“…There are several types of intraspinal cysts reported in dogs, including arachnoid cysts, synovial cysts, dermoid cysts, and ganglion cysts [5,6,13,15]. Of different types of intraspinal cysts, those having connection to the corresponding intervertebral disc have been termed discal cysts, which is a relatively new clinical entity in humans.…”

Spontaneous Regression of a Cervical Intraspinal Cyst in a Dog

et al. 2010

ABSTRACT. We report a cervical intraspinal cyst in a dog that was initially tetraparetic but spontaneously recovered completely. MRI revealed a well-demarcated intraspinal cyst located dorsally to a degenerated intervertebral disc. The location of the cyst and its signal features on MRI resembled those of discal cysts previously reported in humans. It has been reported in dogs that clinical signs of a intraspinal cyst are similar to those of intervertebral disc herniation and both conditions require surgical intervention. Unexpectedly, our case showed rapid spontaneous recovery and the follow-up MRI revealed complete resolution of the intraspinal cyst and spinal cord compression. Spontaneous recovery of degenerative intraspinal cyst may occur in dogs, similar to rare human cases as reported previously.KEY WORDS: canine, intervertebral disc disease, intraspinal cyst, magnetic resonance imaging.

“…Synovial cysts have a synovial-like cell lining and communicate with a joint, whereas ganglion cysts do not 6 . Webb et al 28 recommend that these cysts should be referred to as intraspinal articular cysts until histological confirmation. It is quite possible that cases diagnosed with dorsal compressive spinal lesions on myelography (and attributed only to facet changes or ligamentous and soft tissue hypertrophy), may in fact have synovial cysts contributing significantly to the compression 9 .…”

The Boerboel is a South African large-breed dog resembling a Bullmastiff. The records of Onderstepoort Veterinary Academic Hospital were searched for dogs that had presented, between 1998 and 2003, with symptoms indicative of wobbler syndrome and had undergone survey radiographic and myelographic studies. Ten cases fitted the inclusion criteria. Dogs presented within the first 2 years of life, often with acute onset of symptoms. All presented with pelvic limb and 6 with concomitant thoracic limb ataxia or paresis. Treatment varied and included none (4), prednisolone (2), and dorsal laminectomy (2). Two dogs were euthanased at the time of diagnosis. The breed appears to be affected with a form of spondylomyelopathy that comprises bony malformation of cervical and/or thoracic vertebrae. In 8 dogs, malformations were evident on survey radiographs and were characterised by enlarged, irregular articular facets and associated medial deviation of the pedicles. These changes resulted in axial compression of the spinal cord best seen on ventrodorsal or dorsoventral myelographic studies. Multiple vertebrae were affected in some dogs and lesions were not confined to the caudal area of the cervical spine. Three dogs were alive and without symptoms at follow-up. Four were euthanased as a result of the disease and 1 died as a result of post-operative complications. Two additional dogs presenting with wobbler clinical signs are also described. One had medial deviation of the T5 and T6 caudal pedicles and 1 dog suffered from multiple cervical articular facet synovial cysts.

“…Ganglion cysts are relatively common in humans [7], however, only a small number of cases (including a horse [3] and several dogs [2, 4, 8]) have been reported in the veterinary literature. To our knowledge, MR images of ganglion cysts formation relating to the canine stifle joint have not been previously reported.…”

A 10-year-old, neutered male Labrador retriever presented with progressive left hind lameness. Ultrasonography revealed large, subcutaneous, ovoid cysts around the stifle joint. Radiographic and computed tomographic images revealed periosteal reaction of the distal femur. Magnetic resonance (MR) imaging showed a large cyst that was hypointense in T1-weighted images, hyperintense in T2-weighted images and had a thin lining that was enhanced by intravenous gadonium injection. The cyst communicated with the joint cavity and other small cysts around the joint. Histopathology of an excisional biopsy specimen led to diagnosis of ganglion cyst. This report provides MR images of a ganglion cyst in a canine stifle.
