|January 18, 2024
Summary
Ovarian stromal tumors with minor sex cord elements are rare. This case highlights atypical magnetic resonance imaging (MRI) findings, including diffusion-weighted imaging (DWI) and contrast enhancement, that may suggest this rare ovarian tumor.
Area of Science:
- Gynecologic Oncology
- Radiology
- Pathology
Background:
- Ovarian stromal tumors with minor sex cord elements are rare.
- Specific imaging features for diagnosis are not well-defined.
Observation:
- A case of an 81-year-old woman with constipation and a pelvic mass is presented.
- MRI revealed a well-circumscribed mass with specific signal intensities on T1WI and T2WI.
- Dynamic contrast-enhanced T1WI and DWI showed peripheral enhancement and low apparent diffusion coefficient values.
Findings:
- Pathological assessment confirmed a fibrothecoma with minor sex cord elements.
- Preoperative diagnosis of this rare tumor is challenging.
Implications:
- Atypical findings on DWI and dynamic contrast enhancement may suggest this rare ovarian tumor.
- Consideration of this rare entity is important for preoperative diagnosis.
- Further research into imaging characteristics is warranted.

02:07Oogenesis
63.7K
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

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.

01:27Ovarian Cycle
1.2K
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...
