10mo FS Dachshund with recent onset of paraparesis neuroanatomically localized to T3–L3. There is a well‐defined, bone‐attenuating
mass arising from the caudal lamina of T6 that appears contiguous with more normal adjacent bone of the basilar part of the T6 spinous
process (a–c: arrow). Encroachment into the vertebral canal implies spinal cord compression (a–c: arrowhead), although the cord is not
clearly delineated. The mass also has T2 (d,e: arrow) and T1 (not shown) intensity similar to adjacent normal bone, and spinal cord
compression is documented (d,e: arrowhead). Surgical excision biopsy revealed the mass to be a solitary osteochondroma (f).
