Meigs'‐Like Syndrome Secondary to Remnant Ovarian Tissue in a Cat

ABSTRACT A 4‐year‐old spayed female domestic shorthair cat was evaluated for a three‐day history of dyspnea and lethargy. Abdominal ultrasonography and thoracic radiographs revealed the presence of abdominal and pleural effusions, along with both uterine horns and a rounded mass in the pelvic abdomen. Both effusions were compatible with modified transudates rich in protein and negative for infectious disease. The mass and uterus were surgically removed, and histology revealed a normal cycling ovary and uterine glandular hyperplasia. At the two‐week follow‐up after surgery, the effusion had completely disappeared, and the cat had fully recovered. In human medicine, Meigs' syndrome is characterized by the triad of pleural and abdominal effusions along with ovarian mass, most commonly fibromas. This is a report describing a Meigs' like syndrome in a young cat with ovarian remnant tissue.
