Plain-English summary
Two spayed female dogs were brought in because of an abdominal mass, which raised concerns about possible ovarian tumors. To investigate further, the veterinarians used a special imaging technique called F-FDG PET/CT, which showed some increased activity in the tumors but no signs of spreading to nearby tissues or lymph nodes. After surgery, the tumors were confirmed to be granulosa cell tumors, which are a type of ovarian tumor. This case demonstrates that F-FDG PET/CT can be a useful tool for detecting these tumors in dogs.

Abstract
Two spayed female mongrels were presented for an abdominal mass and metastasis examination. To investigate suspected ovarian tumours and metastasis,F-2-deoxy-2-fluoro-D-glucose (F-FDG) positron emission tomography (PET)/computed tomography (CT) was performed.F-FDG PET revealed mildly increased glucose uptake (maximum standardised uptake values, 2.03 and 1.32) without hypermetabolic invasion to adjacent tissue or lymphadenopathy. Histopathological examination confirmed that the excised ovarian tumours were granulosa cell tumours without angiolymphatic invasion. This is the first case report describing the feasibility of usingF-FDG PET/CT to detect canine granulosa cell tumours, highlighting their characteristics and identifying metastasis to regional lymph nodes or visceral organs.
