The patient underwent abdominopelvic mass resection, and histopathology evaluation confirmed immature ovarian teratoma, an uncommon ovarian germ cell tumor representing less than 1% of ovarian teratomas.

Immature ovarian teratomas usually affect a younger age group and produce serum AFP elevation in 50% of cases.

On cross-sectional imaging, a prominent solid component containing calcifications and small foci of fat is suggestive.
