Spinal arachnoid pseudocysts in 10 rottweilers.
Ten rottweilers presenting with spinal arachnoid pseudocysts were investigated. In six dogs, the lesions were localised dorsally at C2-C3; in three dogs, dorsally and ventrally at C5-C6; and, in one dog, dorsally and ventrally at C6-C7. Clinical signs were consistent with focal compression of the affected spinal cord segments. The animals showed ataxia of all four limbs, with truncal ataxia and marked hypermetria in cases of C2-C3 involvement, or ambulatory tetraparesis in cases of C5-C6 or C6-C7 involvement. Other than signs indicative of spina bifida in one dog, no abnormalities could be detected on plain radiographs. Myelography was used to define the localisation and extent of the pseudocysts. Additional information was obtained using magnetic resonance imaging in five dogs. Five dogs underwent a dorsal laminectomy; in three cases, the pseudocyst was treated by marsupialisation and, in two, by durectomy.
