    Chronic ectopic pregnancy involves slow tubal wall disintegration and bleeding, forming a pelvic hematocele. Early diagnosis is possible with increased awareness of this entity.

    Area of Science:

    • Gynecology
    • Reproductive Medicine
    • Pathology

    Background:

    • Chronic ectopic pregnancy is a rare tubal pregnancy variant.
    • Characterized by gradual tubal wall disintegration and slow/repeated hemorrhaging.
    • Leads to the formation of a pelvic mass, often a hematocele.

    Purpose of the Study:

    • To review pathologically proven cases of chronic ectopic pregnancy.
    • To describe the sonographic features of this entity.
    • To emphasize the importance of preoperative diagnosis.

    Main Methods:

    • Retrospective review of 22 pathologically confirmed cases.
    • Analysis of clinical presentation and sonographic findings.
    • Comparison with differential diagnoses.

    Main Results:

    • The pelvic mass was identified as a hematocele (inflammatory mass of blood clots, organized hematomas, adhesions).
    • Sonographic findings include extrauterine, complex adnexal/cul-de-sac masses.
    • Masses can mimic pelvic inflammatory disease, endometriosis, or leiomyomas.

    Conclusions:

    • Chronic ectopic pregnancy presents with a protracted, mildly symptomatic course.
    • Sonographic identification of complex extrauterine masses is key.
    • Increased awareness can facilitate preoperative diagnosis, distinguishing it from other gynecologic conditions.
