- 10 year old MN Lab x collie with persistent haematuria, otherwise well
- Right kidney mass identified – could not reach with 1 1/2 inch needle so hope to do tru-cut biopsy
- What is your impression of this mass? Do you think it is safe to biopsy?
- Do you think the left kidney is normal? I was querying area at corticomedullary junction of cranial pole…
- First 2 videos right kidney, next 2 videos left kidney

There is an expansive,
There is an expansive, primarily hypoechoic solid mass lesion distorting the mid to cranial right kidney. This looks like primary neoplasia as opposed to a benign lesion although a beingin lesion like a hemangioma may be possible. Possible etiologies may include lymphoma, sarcoma (hemangiosarcoma, histiocytic), adenocarcinoma, blastoma, etc.
I see the small lesion ion the LK. To me, it looks like a cystic lesion. I dont think this is neoplastic but should be monitored. Otherwise, the LK exhibits age related changes but normal overall architecture
I think the RK mass is safe to biopsy if the coag panel is normal. Three veiw chest rads would be suggested if not done.
If thoracic rads are clear,
If thoracic rads are clear, nephrectomy would be a better option that Tru-cut biopsy as it would be both diagnostic and therapeutic.
Would nephrectomy be required
Would nephrectomy be required if mass was lymphoma?
i think any unilateral mass
i think any unilateral mass should be removed surgically as the renal capsule holds things in pretty well assuming no macroscopic mets anywhere. Could fna shopping spree LK, spleen, liver looking for any evidence of lsa then do the nephrectomy if clean.
Thank you for all the
Thank you for all the advice.
I will let you know how this case progresses.
Just to update –
Just to update – Unfortunately no specific diagnosis on trucut biopsy, I think round cell neoplasia is unlikely and have recommended nephrectomy.
1. The majority of the fragments consist of blood and fibrin clots – 12 fragments ranging from 0.7 mm to 3 mm. One of the blood clot is surrounded by small amount of loose fibrous tissue. 2. One fragment represent mature collagenous tissue with scattered myofibres – 1.5 x 4.5 mm. 3. One fragment represents the skin – 1 x 1.2 mm. There are no significant findings. 4. One fragment represents the kidney – 0.75 x 3 mm. Small portion of cortex with 4 glomeruli and medulla. There are no significant findings.
COMMENT The submitted samples represent blood and fibrin clots, skin, collagenous tissue with myofibres and normal kidney. Is it possible that the mass represents hematoma or cavitary lesion filled with blood (hemangiosarcoma, renal carcinoma, etc)? The blood and fibrin clots can be also associated with the procedure.
