[Nephroblastoma in a 2-year-old female dog]. / Nephroblastom bei einer 2-jährigen Hündin.

An intact female 2-year-old boxer presented with polydipsia, polyuria, and decreased feed intake. Palpation of the abdomen was painful. Sonography revealed an abdominal mass of the left kidney causing displacement of the organs located in the cranial and mid-abdomen. Dimen sion and invasiveness of the process were evaluated both by contrast enhanced ultrasound (CEUS) and contrast-enhanced computed tomography. Histopathological examination of a biopsy sample revealed a nephroblastoma. The case report describes the clinical, sonographic, and computed tomographic results and the outcome in the untreated dog over a period of 5 months.
