Incomplete abortion and hydrometrosis in a squirrel monkey (Saimiri sciureus)

A 6-year-old, primiparous female squirrel monkey, diagnosed as being at approximately 100 days of gestation, developed clinical signs of pregnancy toxemia. An ovariohysterectomy was performed and complete recovery followed supportive treatment. Based on histopathology, a diagnosis of incomplete abortion and hydrometrosis was made.
