Synonym(s): Cystic ovaries, Ovarian cysts, Cystic rete ovarii, Serous cysts


Introduction

  • Cause: spontaneous development of serous, non-functional ovarian cysts throughout the estrous cycle. Follicular cysts (functional) may develop as well; usually found in older sows.
  • Signs: abdominal distention, sometimes with anorexia, weakness or lethargy. If follicular cysts are present, bilateral symmetric hair loss may be seen in the flank region. Declining fertility seen in breeding sows over 15 months of age.
  • Diagnosis: ultrasonography is best; abdominal radiography may show larger cysts.
  • Treatment: ovariohysterectomy.
  • Prognosis: good if ovariohysterectomy is sucessful.

Pathogenesis

Etiology

  • Development of cysts throughout the estrous cycle is normal.
  • Problem becomes if cysts do not regress and become abnormally filled with fluid.

Predisposing factors

General

  • Aging.

Specific

  • Intact sow.
  • Guinea pigs that are obese or are kept alone have increased incidence.

Pathophysiology

  • Nonfunctional serous cysts (cystic rete ovarii) develop during the estrous cycle.
  • Follicular (hormonally active) cysts ocurred in 22.4% of population in one study.
  • Cysts range in diameter from 0.5 to >7 cm, increasing in size and prevalence as the sow ages.
  • Usually both ovaries affected, although if unilateral, the right ovary is more commonly affected.
  • Cysts may be single or multilocular and usually filled with clear fluid.

Timecourse

  • Development as the sow ages.

Epidemiology

  • Very high incidence in intact sows.
