A 2-year-old NM DSH was presented for evaluation of renomegaly on survey radiographs. Urinalysis and CBC were both normal. Mild azotemia was evident on serum biochemistry.
Case Study
06-00301 Turkey C Renal LSA——-NEED SL——–
Sonographic Differential Diagnosis
Strongly suggestive for bilateral renal lymphoma pattern. Dry form FIP is also possible, yet less likely.
Image Interpretation
Hyperechoic medullary rim sign was noted along with ill-defined pelvic fat. Heterogenous, mixed nodular cortical changes were noted. This is strongly suspicious for renal lymphoma or dry form FIP. The right kidney was severely enlarged and measured 6.4 cm. The left kidney measured 7.64 cm with subcapsular halo with similar disruptive changes to the right kidney and more exaggerated nodular expansion.
Outcome
None
Clinical Differential Diagnosis
Lymphoma, hydronephrosis, polycystic kidney disease, granulomatous disease, nephritis, pyelonephritis
