A 28-year-old woman undergoing evaluation for infertility is found to have a submucosal fibroid on transvaginal sonography. According to the FIGO leiomyoma classification system, a Type 2 submucosal fibroid is one in which the intramural portion is:
- A 50% or more of the total fibroid diameter ✓
- B Between 10% and 30% of the total fibroid diameter
- C Less than 10% of the total fibroid diameter
- D Exactly equal to the intracavitary portion
Correct answer: A. 50% or more of the total fibroid diameter
Explanation
The FIGO classification defines Type 2 submucosal fibroids as those with an intramural portion of 50% or more. Type 1 has less than 50% intramural extension, and Type 0 is pedunculated entirely within the cavity. The 50% threshold determines surgical approach, as Type 2 fibroids often require a more complex hysteroscopic or combined approach for excision.
