A 6-month-old NM Persian was presented for evaluation of failing to gain weight and chronic pyrexia. PCV was low (19%), total proteins elevated (10), and negative for FeLV, FIV, and Mycoplasma.

Multi centric lymphoma or dry form FIP
The kidneys presented medullary rim sign with expansive nodular cortical changes and generalized renomegaly. The right kidney measured 4.48 cm. The left kidney measured 3.8 cm. Regional inflammation was noted around both kidneys.
The mesenteric lymph node was enlarged and hypoechoic with irregular disrupted architecture measuring 2.8 x 2.0 cm. A cluster of lymph nodes measured 3.2 cm at the mesenteric root.
Medullary rim kidney with disrupted architecture. Subcapsular halo noted around both kidneys with pericapsular inflammation. Multi centric lymphoma or dry form FIP are the primary differentials in this case. Ultrasound-guided FNA of the kidneys primarily the caudal aspect of the right kidney as well as mesenteric lymph nodes would be recommended. Very guarded prognosis depending on cytology results.
The cranial mediastinum revealed a slight, hypoechoic consolidation as well. This is suggestive for metastatic disease.
FIP, Chronic bacterial infection – peritonitis, pyothorax, Abscess/granuloma
