Ovarian Cycle

Ovarian Cycle

The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle length...

Area of Science:

Reproductive Medicine
Obstetrics and Gynecology

Background:

Cornual pregnancy, a rare form of ectopic pregnancy, poses diagnostic difficulties.
Rupture can lead to severe hemorrhage, making timely diagnosis crucial.

Observation:

A 34-year-old woman presented with suspected left cornual pregnancy at 11 weeks.
Imaging confirmed an eccentric gestational sac near the left uterine cornua with a viable fetus.
The sac was encased by a thin myometrial layer.

Findings:

The patient experienced rupture of the left cornual pregnancy, leading to hemodynamic instability.
Emergency laparotomy revealed a ruptured cornual pregnancy with hemoperitoneum.
Cornual resection was performed, and pathological examination confirmed the diagnosis.

Implications:

This case underscores the diagnostic challenges and catastrophic potential of cornual pregnancy rupture.
Highlights the need for vigilant monitoring and prompt surgical intervention in suspected cases.
Emphasizes the importance of advanced imaging in diagnosing rare ectopic pregnancies.
