T1- and T2-weighted sequences measuring 1.6 x 1.3 x 1.0 cm in the left paracolpium. The lesion was described as a deep infiltrative endometriosis nodule (Figures 1 and 2).

T1- and T2-weighted sequences measuring 1.6 x 1.3 x 1.0 cm in the left paracolpium. The lesion was described as a deep infiltrative endometriosis nodule (Figures 1 and 2).

In the pelvis, uterosacral ligament thickening and several "powder-burn" lesions compatible with foci of peritoneal endometriosis in the ovarian fossae were observed (Figure 3).
(a) Left paracolpium. (b) Same image identifying (1) left pararectal space, (2) tumor in the left paracolpium, and (3) insertion of the left uterosacral ligament.

When the cardinal ligament was incised, a plane of cleavage was observed that usually does not occur with lesions of deep infiltrating endometriosis (Figure 4).
Microscopy of the paracolpal tumor: leiomyoma.

Histopathological evaluation of the paracolpal tumor revealed that it was a leiomyoma (Figure 5).
