case_images: Preoperative findings: (a) Contrast-enhanced computed tomography revealing a 22 x 20 x 8 cm3 pelvic mass with contrast enhancement. Existing structures such as the bilateral internal iliac arteries are surrounded by a tumor (arrow). (b) T2-weighted magnetic resonance imaging showing a large pelvic mass in contact with the uterus that filled the entire pelvic cavity. The tumor mainly shows low signal intensity compared to the myometrium and partially shows high signal intensity similar to that of the partition wall.

case_images: Existing structures, such as the bilateral internal iliac arteries, were surrounded by tumors (Figure 1a). The tumor mainly exhibited a low signal intensity compared to the muscle with a partially high signal intensity, similar to the partition wall (Figure 1b).
case_images: Laparoscopic findings. The mass is grayish-white in color and consists of multiple soft flaps (arrow).

case_images: fig2-2632010X241281240
case_images: The mass was grayish-white in color and comprised multiple flaps (Figure 2).
case_images: Pathological findings. (a) Overall findings: The mass was lobular and multinodular, with some areas of hemorrhage. (b) Hematoxylin and eosin staining: Scale bar, 50 mum. The tumor is composed of nodules of smooth muscle fascicles separated by hydropic connective tissue. (c) Hematoxylin and eosin staining: Scale bar, 50 mum. Extensive stromal hyalinization is present in the background.

case_images: fig3-2632010X241281240
case_images: The morphology consisted of bulbous protrusions (Figure 3a). Histologically, the tumor was lobular and multinodular with some areas of hemorrhage composed of smooth muscle fascicle nodules separated by hydropic connective tissue containing congested vessels (Figure 3b). Extensive stromal hyalinization was observed in the background (Figure 3c).
