Case Reports in Obstetrics and Gynecology
|April 27, 2026
Summary
Isolated fallopian tube torsion (IFTT) is rare. This case highlights an adenomatoid tumor as an unusual cause of IFTT, emphasizing that even small tumors can lead to this condition.
Area of Science:
- Gynecologic pathology
- Surgical oncology
Background:
- Isolated fallopian tube torsion (IFTT) is a rare gynecologic emergency.
- Causes of IFTT are diverse, including intrinsic tubal abnormalities and extrinsic factors.
- Adenomatoid tumors are typically benign, small, and asymptomatic.
Purpose of the Study:
- To report a rare case of IFTT caused by a fallopian tube adenomatoid tumor.
- To highlight the potential of adenomatoid tumors to cause tubal torsion.
Main Methods:
- Case report of a 49-year-old patient with sudden abdominal pain.
- Diagnostic imaging revealing a tubal mass.
- Laparoscopic confirmation of IFTT and tumor.
- Histopathological examination identifying an adenomatoid tumor.
Main Results:
- The patient presented with acute lower abdominal pain.
- Laparoscopy confirmed isolated fallopian tube torsion with a 3-cm solid mass.
- Histology revealed an adenomatoid tumor of the fallopian tube.
Conclusions:
- Adenomatoid tumors of the fallopian tube, though rare, can cause IFTT.
- Even small adenomatoid tumors (3 cm) can precipitate tubal torsion.
- This case expands the differential diagnosis for IFTT.

01:16Uterine Tubes

The uterine or fallopian tubes function as the conduit through which oocytes travel from the ovaries to the uterus. Each fallopian tube measures approximately 10 to 13 cm long and is anatomically divided into the infundibulum, ampulla, isthmus, and interstitial part (or intramural segment). The infundibulum is characterized by its funnel shape and features extensions called fimbriae which reach towards the peritoneal cavity. These fimbriae play a critical role during ovulation as they extend...

01:19Appendicitis
28
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...

01:29Intestinal Obstruction I: Introduction
46
Intestinal obstruction is a partial or complete blockage of the small or large intestine that disrupts the normal flow of intestinal contents through the lumen. This interruption impairs digestion, absorption, and fluid balance, and may lead to serious complications if not treated promptly.Mechanical ObstructionMechanical obstruction occurs when a physical blockage prevents intestinal contents from passing, arising from within the lumen or the bowel wall, or from external compression.Adhesions,...

5.3K
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...

4.4K
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

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.
