Ruptured corpus luteal cyst is one of the commonest causes of spontaneous haemoperitoneum in a woman of reproductive age.
Pathology
Corpus luteum is a thick walled cystic structure that is prone to internal haemorrhage, and sometimes peritoneal rupture.
Clinical features
- asymptomatic
- severe abdominal pain
- peritoneal irritation
- delayed menstrual cycle if concomitant with pregnancy
Radiographic features
Ultrasound
- complex adnexal cyst
- rim of increased echogenicity surrounding a cystic component
- free fluid with areas of increased echogenicity representing hemoperitoneum
- on Doppler, peripheral vascularity may be seen
- at times the entire rupture and haemorrhage form an organised haematoma and a
complexvascularrcomplex vascular adnexal mass
CT
- well circumscribed cystic lesion
- thick walled cyst (<3 mm) with inhomogenous contrast enhancement
- high attenuation component (45-100 HU)
- “fluid-fluid hematocrit” level
- hemoperitoneum with free fluid near the source of bleeding
having acan have high attenuation value( 60(60-65 HU), “sentinel clot” andfurtherthe attenuation of free fluid reduces further from the source
Differential diagnosis
Possible considerations include
- ruptured ectopic pregnancy: evaluation of serum βhCG-levels is necessary to differentiate ruptured corpus luteal cyst from ruptured ectopic pregnancy, which may have a similar presentation
- ruptured ovarian cyst: no haemoperitoneum
