Myomas and Adenomyosis: Impact on Reproductive Outcome

Figure 1

FIGO classification of myomas. FIGO classification system of myomas introduced by Munro and colleagues in 2011 [31] is based on the relationship of the fibroid with the uterine wall. According to this classification, type 0 to type 8, the last one representing fibroids, which cannot otherwise be classified, have been proposed, whereas for a subset of fibroids, two numbers may be applicable, the first one referring to the relationship with the endometrium and the second one with the perimetrium. This possibility can indirectly imply the size of a myoma, which, for instance, extends throughout the uterine wall protruding into the uterine cavity and concurrently distorts the outline of the uterus (type 2–5). Type 0: pedunculated intracavitary. Type 1 submucosal < 50% intramural. Type 2: submucosal ≥ 50% intramural. Type 3: entirely intramural, contacting the endometrium. Type 5: subserosal ≥ 50% intramural. Type 6: subserosal < 50% intramural. Type 7: subserosal pedunculated. Type 8 (not shown in the figure): others, that is, cervical, originating from the round ligament or parasitic.
