ABSTRACT
Background: Teratoma is an almost always benign tumor, with a wide variability
in its location; its location in the round ligament is extremely rare.
Clinic case: 30-year-old patient, with a history of a full-term pregnancy. On routine
ultrasound examination, a 46 x 35 mm left paraovarian cystic lesion was reported,
with no solid, fatty component or calcifications. In the gynecological examination a
mass was palpated above the uterus, oriented to the left side, non-painful. The rest
of the physical examination passed without other alterations. The initial diagnostic
impression was of abdomino-pelvic teratoma supported by transvaginal ultrasound
in which the ovaries were normal, with a mass of mixed echogenicity of 50 x 40 x
46 mm, with echolucent and echogenic areas of variable intensity towards the left
superior iliac fossa, without contact with the ovary. The round ligament was sectioned
on both sides of the mass and removed without complications; the histopathologic
report was: mature cystic teratoma.
Conclusions: The round ligament is an infrequent location of dermoid cysts that
should be considered in the differential diagnoses of pelvic masses; it is amenable to
surgical treatment laparoscopically.
