CT of the spine, plain, with myelogram – There were 14 vertebrae with symmetrical rib pairs. The 9th thoracic vertebra (counting from cranial to caudal) was a short vertebra with short and thin ribs. The 14th thoracic vertebra had bilaterally symmetric free ribs. There were 7 lumbar vertebrae.
The myelogram showed disc associated extradural mass effects with pronounced compression of the ventral subarachnoid space level with T13/14, T14/L1 and L1/2.
The most significant myelocompressive effect was noted L1/2 where 25% of the vertebral canal diameter was occupied. The epidural mass effect extended cranially along the caudal half of L1 and was slightly deviated to the left. A mineral opaque focus was associated with the epidural mass effect level with L1. Moreover, there was circumferential thinning of the subarachnoid space suggestive of spinal cord swelling and the disc L1/2 showed a central vacuum phenomenon.
Level with T13/14 a left-sided ventral and T14/L1 a ventral mild epidural mass effect restricted to the intervertebral disc space was noted.
Mild protrusions were noted level with C2/3, L6/7 and L7/S1 without significant myelo-/neurocompressive effects.
Multifocal disc mineralizations were seen.
Multiple small cystoliths were present.
The liver presented mild contour irregularity.
There was anesthesia related splenomegaly.
