Summary
Ovarian ectopic pregnancy is rare, especially in the second trimester. This case highlights the challenges in diagnosing and managing an unruptured ovarian pregnancy, even with classic histologic criteria.
Area of Science:
- Reproductive Medicine
- Gynecologic Surgery
- Diagnostic Imaging
Background:
- Ovarian ectopic pregnancy is a rare condition, typically diagnosed in the first trimester.
- Rupture often necessitates urgent surgical intervention.
Observation:
- A 37-year-old woman presented with symptoms suggestive of pregnancy.
- Ultrasound revealed a 16-week, 4-day gestation within the right adnexa, without an intrauterine pregnancy.
- The patient underwent laparotomy for a right salpingo-oophorectomy.
Findings:
- An unruptured second-trimester ovarian ectopic pregnancy was successfully removed.
- Histopathologic evaluation confirmed the Speigelberg criteria for ovarian pregnancy.
- Preoperative diagnosis and treatment decisions were not aided by the Speigelberg criteria in this instance.
Implications:
- This case underscores the diagnostic and management complexities of late-term ovarian ectopic pregnancies.
- It suggests that classic histologic criteria may not always be instrumental in guiding clinical management.
- Further research into advanced imaging or diagnostic markers for ovarian ectopic pregnancy is warranted.

01:27Ovarian Cycle
5.6K
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...

01:22Oogenesis
5.2K
Oogenesis, the process of developing egg cells (female gametes), occurs within the ovaries and is fundamental to female fertility. This sequence begins during fetal development when diploid oogonia in the developing ovaries undergo mitotic divisions to produce primary oocytes. By birth, these primary oocytes enter prophase I of meiosis but become arrested in this stage, remaining suspended until puberty.
Each primary oocyte is surrounded by a layer of pre-granulosa cells, forming what is...

71.5K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

01:26Ovaries
3.5K
The ovaries are roughly the size of almonds and measure approximately 2 to 3 centimeters in length. These paired structures are situated within the pelvic region and are anchored by the mesovarium—a peritoneal extension that also connects them to the wider structure of the broad ligament. The support system extends to the suspensory ligament, housing blood and lymphatic vessels. In addition, the ovarian ligament tethers the ovaries to the uterus.

01:30Hormonal Control of the Ovarian Cycle
7.8K
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

210.9K
Meiosis II is the second and final stage of meiosis. It relies on the haploid cells produced during meiosis I, each of which contain only 23 chromosomes—one from each homologous initial pair. Importantly, each chromosome in these cells is composed of two joined copies, and when these cells enter meiosis II, the goal is to separate such sister chromatids using the same microtubule-based network employed in other division processes. The result of meiosis II is two haploid cells, each...
