A twelve-year-old, spayed female Yorkshire Terrier with intermittent vomiting was diagnosed with regional granulomatous enteritis through histopathological examination. On ultrasonography and computed tomography, a focal thickened duodenal wall showed a mass-like appearance with indistinct wall layers. Marked uptake of 18F-fluorodeoxyglucose was observed from the mass on positron emission tomography-computed tomography. Regional granulomatous enteritis is a rare form of inflammatory bowel disease and may have similar imaging features with intestinal tumors. This is the first study describing the diagnostic imaging features of ultrasonography, computed tomography and positron emission tomography-computed tomography of regional granulomatous enteritis in a dog.

A 10-year-old, intact female Yorkshire terrier had multiple pulmonary nodules on thoracic radiography and ultrasonography, with no lesions elsewhere. Computed tomography (CT) and positron emission tomography and computed tomography (PET-CT) using 18F-fluorodeoxyglucose (FDG) were performed to identify metastasis and undetected primary tumors. On CT examination, pulmonary nodules had a hypoattenuating center with thin peripheral enhancement, suggesting ischemic or necrotizing lesion. In PET-CT at 47 min after intravenous injection of 11.1 MBq/kg of FDG, the maximum standardized uptake value of each pulmonary nodule was about from 3.8 to 6.4. There were no abnormal lesions except for four pulmonary nodules on the CT and PET-CT. Primary lung tumor was tentatively diagnosed and palliative therapy using 2 mg/kg tramadol and 2.2 mg/kg carprofen twice per day was applied. After the dog’s euthanasia due to deteriorated clinical signs and poor prognosis, undifferentiated pulmonary adenocarcinoma was diagnosed through histopathologic and immunochemistry examination. To the best of the authors’ knowledge, this is the first study of CT and PET-CT features of canine pulmonary adenocarcinoma. In this case, multiple pulmonary adenocarcinoma could be determined on the basis of FDG PET-CT through screening the obvious distant metastasis and/or lymph node invasions and excluding unknown primary tumors.
