ABSTRACT
A 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.

A 10-year-old, neutered female, Australian Shepherd was referred for acute respiratory distress and a history of chronic exogenous steroid administration. On thoracic radiographs, a severe increase in mineral opacity characterized as a generalized unstructured interstitial pulmonary pattern, diffuse calcinosis cutis, and moderate hepatomegaly were noted. Cor pulmonale was identified on echocardiography. The patient developed a pneumothorax following sampling and had a cardiac arrest. Postmortem histopathology of the lungs revealed pulmonary interstitial mineralization and alveolar microlithiasis. This report supports including generalized pulmonary mineralization due to chronic exogenous steroid administration as a differential diagnosis for dogs with these clinical and imaging findings.
