What is the treatment for a hemorrhagic ovarian cyst?

Treatment of Hemorrhagic Ovarian Cysts

Most hemorrhagic ovarian cysts in premenopausal women require no specific treatment and resolve spontaneously with conservative management. 1

Management Based on Size and Patient Characteristics

Premenopausal Women

• Typical hemorrhagic cysts ≤5 cm: No further management required 1
• Typical hemorrhagic cysts >5 cm but <10 cm: Follow-up ultrasound in 8-12 weeks 1
  • If the cyst persists or enlarges during follow-up: Referral to ultrasound specialist, gynecologist, or MRI is recommended 1
• Hemorrhagic cysts with changing morphology or developing vascular components: Referral for specialist evaluation 1

Postmenopausal Women

• Hemorrhagic cysts should not typically occur in postmenopausal women 1
• When found in postmenopausal women (<10 cm): Further evaluation by ultrasound specialist, gynecologist, or MRI is required 1

Diagnostic Features

• Ultrasound is the first-line diagnostic tool for hemorrhagic ovarian cysts 1, 2
• Characteristic findings include:
  • Reticular pattern (fine thin intersecting lines representing fibrin strands) 1
  • Retracting clot (avascular echogenic component with angular, straight, or concave margins) 1
  • Peripheral vascularity with absence of internal blood flow 1

Management of Complications

Ruptured Hemorrhagic Cysts

• Most ruptures are self-limiting and require only conservative management 2
• Indications for surgical intervention (typically laparoscopic):
  • Hemodynamic instability 3, 2
  • Diagnostic uncertainty 3, 2
  • Persistent significant bleeding 3

Patients on Anticoagulation Therapy

• Higher risk of significant hemorrhage into cysts 4
• For cyst hemorrhage while on anticoagulants:
  • Interrupt aspirin for 3 days following hemorrhage onset 1
  • Consider restarting anticoagulants between 7-15 days after hemorrhage onset 1
  • For patients on dual antiplatelet therapy: Continue P2Y12 inhibitor while interrupting aspirin 1

Special Considerations

• Hemorrhagic cysts are functional cysts resulting from bleeding into follicular or corpus luteum cysts 5, 6
• Most common in reproductive-age women during the luteal phase of the menstrual cycle 6
• Rare in patients with PCOS due to anovulation 6
• Avoid fine-needle aspiration of ovarian cysts as this is contraindicated 1

Follow-up

• For resolving cysts: No further follow-up needed 1
• For persistent cysts: Consider gynecologic referral for further management 1
• Risk of malignancy in sonographically benign-appearing lesions is extremely low (<1%) 1

Pitfalls to Avoid

• Do not perform invasive procedures during active hemorrhage 1
• Avoid misdiagnosing pedunculated fibroids as ovarian masses 1
• Do not assume all adnexal masses in premenopausal women are functional - follow appropriate guidelines for persistent masses 1
