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

## TL;DR

A spayed cat showed symptoms similar to Meigs' syndrome in humans, caused by leftover ovarian tissue, and fully recovered after surgery.

## Contribution

This is the first reported case of Meigs' like syndrome in a cat due to remnant ovarian tissue.

## Key findings

- The cat had pleural and abdominal effusions along with an ovarian mass.
- Surgical removal of the mass and uterus led to full recovery.
- Histology confirmed normal ovarian tissue and uterine hyperplasia.

## 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.
