This paper describes the imaging features of ovarian metastases from a
denocarcinoma of the colon in adolescent females. We reviewed retrospe
ctively abdominal and pelvic computed tomographic and pelvic ultrasoun
d examinations, histologic slices, and clinical charts of six adolesce
nt females with ovarian metastases secondary to adenocarcinoma of the
colon. One patient had ovarian metastasis at presentation and was pres
umed to have a primary ovarian tumor. The ovarian metastases were eith
er solid (n = 3), complex with both solid and cystic components (n = 2
), or multilocular cysts (n = 1). The ovarian lesions were large, rang
ing from 6 cm to 18 cm in diameter. Colorectal carcinoma in adolescent
females is frequently associated with ovarian metastases. One imaging
characteristic differs in adult and adolescent ovarian metastases, al
though they do have features in common: in adolescents, a smaller prop
ortion of colorectal ovarian metastases are multicystic (17 %) compare
d with the adult series (45 %). These lesions are frequently large and
may be complex, multicystic, or solid. Although it is a rare disease,
the differential dignosis of adnexal masses in adolescent females sho
uld include ovarian metastases from adenocarcinoma of the colon.
