Computed tomographic findings in a canine ovarian teratoma
AbstractA 2‐year‐old, intact female, Labrador Retriever was referred for progressive abdominal distension, assessed by emergency clinicians as being extrauterine in origin on AFAST. Abdominal radiographs and ultrasound identified a large, lobulated, partially mineralized, soft tissue, mid‐abdominal mass and gravid uterus. Contrast‐enhanced CT identified a mixed fat to soft tissue attenuating mass with a complex internal mineralized matrix, heterogeneous contrast enhancement, receiving blood from the left ovarian artery. Histology confirmed a left ovarian teratoma, diffuse endometrial hyperplasia, and fetal implantation. The patient had a good post‐operative outcome for 2 years, but was later diagnosed with primary cranial mediastinal neuroendocrine carcinoma.
