A 28-year-old woman with heavy menstrual bleeding is found to have a 3 cm submucous fibroid on saline infusion sonography. According to the FIGO subclassification of submucous leiomyomas, which type is one that is entirely within the endometrial cavity with no intramural extension?
- A Type 0 ✓
- B Type 1
- C Type 2
- D Type 3
Correct answer: A. Type 0
Explanation
The FIGO leiomyoma classification defines Type 0 submucous fibroids as entirely intracavitary with no intramural component. Type 1 has less than 50% intramural extension, and Type 2 has 50% or more intramural extension. Type 3 is intramural but contacts the endometrium without cavity distortion. This classification guides surgical planning, as Type 0 is most amenable to hysteroscopic resection.
