Portomesenteric Vein Thrombosis After Excision of Parasitic Peritoneal Myomas

Multimodal imaging for diagnosis and management of parasitic peritoneal myoma with myxoid degeneration after laparoscopic‐assisted myomectomy with electric power morcellation

“…For preoperative navigation work up, the blood supply to the pelvic mass was analyzed by 128‐row multidetector dynamic computerized tomography (CT) with multiplanar reconstruction (Fig. a) . The pelvic mass (colored light green), which was located in front of the uterus (colored light blue), was supplied by the left gastro‐omental artery, which originated from the splenic artery (colored purple) (Fig.…”

“…Iatrogenic parasitic myoma may occur when a small myoma fragment generated during uncontained tissue extraction in minimally invasive surgery for the treatment of uterine myoma is seeded and subsequently grows . The sites of development include the incision site of surgical entry on the abdominal wall and anywhere on the surface of the peritoneal cavity, including the intestinal serosa, peritoneum and omentum . During the growing process, at the ectopic implantation site, a parasitic myoma may obtain its blood supply from aberrant blood vessels .…”

“…The sites of development include the incision site of surgical entry on the abdominal wall and anywhere on the surface of the peritoneal cavity, including the intestinal serosa, peritoneum and omentum . During the growing process, at the ectopic implantation site, a parasitic myoma may obtain its blood supply from aberrant blood vessels . However, such neovascularization is infrequently encountered in common gynecological surgery.…”

“…The opportunities to excise parasitic peritoneal myoma have increased as greater awareness has led to an increased rate of detection . However, the imaging characteristics of parasitic peritoneal myoma have not yet been well characterized, especially when it demonstrates an unusual appearance on diagnostic imaging ( i.e., appears as an entity other than ordinary leiomyoma).…”

“…The opportunities to excise parasitic peritoneal myoma have increased as greater awareness has led to an increased rate of detection . However, the imaging characteristics of parasitic peritoneal myoma have not yet been well characterized, especially when it demonstrates an unusual appearance on diagnostic imaging ( i.e., appears as an entity other than ordinary leiomyoma). Thus, when the excision of an unusual pelvic mass that has developed after minimally invasive myoma surgery is planned, the evaluation of imaging findings, including the imaging‐based identification of feeding vessels, could play a significant role in diagnosis and surgical management.…”
