The importance of our case lies in its contribution to the limited global literature on hepatic lipomas and its demonstration of how such rare entities can be encountered in routine clinical practice. By presenting detailed imaging features and discussing potential diagnostic dilemma, this case enhances awareness among clinicians and radiologists.

Surgical removal of the horn and left fallopian tube was performed, and the patient recovered well. This case highlights a common diagnostic pitfall, as rudimentary horn pregnancy is frequently misidentified on ultrasound as an abdominal or intrauterine gestation. Recognition of key ultrasonographic features, including lack of continuity with the endometrial cavity, a myometrial mantle surrounding the gestational sac, and a vascular pedicle, may facilitate earlier diagnosis and reduce the risk of catastrophic rupture.
