Physiopathology and semiology concepts were reviewed and two clinical reports, one of them not showing symptoms, were described for the USP swine herd at Pirassununga, State of São Paulo, Brazil. Ovarian cysts in both ovaries were detected by rectal palpation in the sow showing infertility, irregular heat, vulva and clitoris edema. Ovarian cysts in the left ovary were noticeable through rectal palpation in the sow that showed no symptoms. Ovarian cysts visualization and characterization size and degree of lutheinization was possible using ultra-sonography. Post-mortem macro evaluation of the lesion confirmed these observations.
