[edit] Discussion of Ovarian hyperstimulation syndrome

  • Ovarian hyperstimulation syndrome is usually iatrogenic secondary to ovarian stimulant drug therapy for infertility but may occur as a spontaneous event in pregnancy.
  • The syndrome consists of ovarian enlargement with extravascular accumulation of exudates leading to weight gain, ascites, pleural effusions, intravascular volume depletion with hemoconcentration, and oliguria in varying degrees.
  • Pain, abdominal distention, nausea, and vomiting are frequently seen.

[edit] Imaging Findings for Ovarian hyperstimulation syndrome

  • The imaging findings are similar at US, CT, and MR imaging.
  • Ovarian enlargement by distended corpora lutea cysts of varying sizes.
  • Because the enlarged follicles are often peripheral in location, a "wheel spoke" appearance has been described, with stromal ovarian tissue located centrally with surrounding cysts.
  • Familiarity with ovarian hyperstimulation syndrome and the appropriate clinical setting should help avoid the incorrect diagnosis of an ovarian cystic neoplasm.
