Abstract

Malignant mixed Mullerian tumors (MMMT) are rare aggressive tumors that typically arise fromthe female genital tract. This malignancy has an extremely poor prognosis due to its rapid growthand the high associated incidence of both local recurrence and distant metastases. Althoughintraperitoneal metastasis from MMMT is relatively common, no reports exist regarding theradiologic findings of intestinal metastasis from MMMT. Here, we report a case of MMMT withsecondary small bowel metastasis and the associated radiologic findings.

Figure

  • Fig. 1 a. Contrast-enhanced axial CT image shows irregular wall thickening of the small bowel (arrow) with enlarged mesenteric and retroperitoneal lymph nodes (arrowhead). b. Contrast-enhanced axial CT scan at the pelvic level shows a poorly enhancing mass in the uterus. The mass extends into the endometrial cavity.

  • Fig. 2 (a) Sagittal T2-weighted MR image shows a large mass with slightly high signal intensity (arrows) in the uterus that extends to the uterine cervix. Pre-contrast (b) and gadolinium enhanced (c) axial fat-suppressed T1-weighted MR image shows less heterogeneous enhancement of the tumor relative to the adjacent myometrium.

  • Fig. 3 a. A photograph of the gross uterine specimen shows a poorly circumscribed infiltrative yellow, solid mass in the endomyometrium with invasion of more than one half of the myometrium. b. The gross small bowel specimen shows an irregular mass (arrows) that is adherent to the serosal surface of the ileum.
