Patients with which of the following gynecologic condition suffers from spasmodic dysmenorrhoea?
**Core Concept**
Spasmodic dysmenorrhoea is a type of dysmenorrhoea characterized by painful menstrual cramps caused by uterine contractions. This condition is often associated with a specific gynecologic condition that affects the uterine muscles, leading to abnormal contractions.
**Why the Correct Answer is Right**
The correct answer is associated with a condition called **adenomyosis**, where endometrial tissue grows into the muscular wall of the uterus. This leads to abnormal uterine contractions, causing spasmodic dysmenorrhoea. The pathophysiology involves the invasion of endometrial tissue into the myometrium, which disrupts normal uterine function and leads to painful contractions.
**Why Each Wrong Option is Incorrect**
* **Option A:** Fibroids (leiomyomas) can cause dysmenorrhoea, but they are more likely to cause non-specific, non-spasmodic pain and heavy menstrual bleeding.
* **Option B:** Endometriosis can cause dysmenorrhoea, but it is more likely to cause cyclic pelvic pain and dyspareunia, rather than spasmodic dysmenorrhoea.
* **Option C:** Polyps are usually asymptomatic and may not cause significant pain or bleeding.
**Clinical Pearl / High-Yield Fact**
Adenomyosis should be considered in patients with spasmodic dysmenorrhoea, particularly if they have associated heavy menstrual bleeding and a tender, enlarged uterus on pelvic exam.
**Correct Answer:** C. Adenomyosis
