CT case report highlights metastatic uterine cancer in pet pig

A new case report in the Journal of Veterinary Diagnostic Investigation describes an antemortem diagnosis of metastatic endometrial adenocarcinoma in a 13-year-old Vietnamese Pot-bellied sow, using computed tomography to identify diffuse cystic and mineralized uterine masses, multiple pulmonary nodules, and abdominal lymphadenopathy before death. The sow presented with five days of blood-tinged mucoid vulvar discharge, plus a four-month history of intermittent coughing and weight loss. The report adds a modern imaging-based diagnosis to a sparse literature on reproductive tract neoplasia in pet pigs; a 2004 JVDI case similarly documented metastatic endometrial adenocarcinoma in an aged Vietnamese pot-bellied pig, but that diagnosis was made after euthanasia.

Why it matters: For veterinary professionals, the case is a reminder that chronic vulvar discharge, weight loss, coughing, and nonspecific decline in older intact female pigs can reflect advanced uterine malignancy, not just infectious or benign reproductive disease. CT helped localize the primary uterine process and characterize likely metastatic spread, supporting clinical decision-making before necropsy. More broadly, advanced imaging is increasingly part of companion pig medicine, especially as pet parents seek workups similar to those offered in dogs and cats, and veterinary radiology groups note CT’s growing role across species.

What to watch: Watch for whether this report prompts more case recognition, earlier imaging referral for geriatric intact sows, and stronger discussion of reproductive screening and elective sterilization in pet pigs. (pubmed.ncbi.nlm.nih.gov)
