Vertebral dorsal process tumor in 3 years old Akita dog

Neurological / CT scan case:

-A 3 years old akita 35 kg b.wt. dog was presented to our hospital (Dr Paws veterinary Hospital) with:

1. Acute progressive signs of neurological dysfunction; HL para paresis, urine retention/overflow incontinence.
2. Dog was severely emaciated, stop to eat and drink (4 days before presentation).

With neurological examination, the dog has UMN hind limb deficits as following;

1. Patellar reflex of both HL was exaggerated (+3)
2. Sciatic reflex of both HL was exaggerated (+3)
3. Cranial tibial reflex of both HL was normal (+2)
4. Withdrawal reflex was normal (+2)
5. Deep pain sensation was subnormal/ reduced (+1)
6. Anal/perineal reflexes was normal (+2)
7. Panniculus reflex was reduced over the both sides of the back along the whole vertebral column.

-The site of neurological dysfunction was localized to T3-L3 spinal segments.

-Blood parasites was excluded but tests are not available.

With x. ray;

– Osteolysis of the dorsal process of the L2/L3 was evident. Further imaging modalities (C.T) was recommended.

With C.T;

1. Severe Osteolysis of the L2-L3 dorsal process and lateral vertebral buttress suggesting Osteosarcoma (OSA) with epidural space metastasis and myelopathic syndrome (Spinal cord swelling).
2. Significant soft tissue swelling around the affected dorsal process and lumbar vertebrae.
3. The visceral organs (Liver, Spleen, Stomach and pancreas) have irregular borders, rough surfaces, heterogeneous consistency suggesting metastasis with severely increased dimensions suggesting metastatic tumors.
4. Urinary bladder was severely enlarged (UMN urinary flow incontinence).
5. Regional and distant lymph nodes was enlarged.
6. The lungs were clear with no respiratory manifestations
