[Focal liver lesion after normal pregnancy]

Area of Science:

• Gynecology
• Oncology
• Radiology

Background:

• Choriocarcinoma is a rare gestational trophoblastic neoplasm.
• Liver metastases are a potential complication of choriocarcinoma.
• Focal liver lesions can present diagnostic challenges during or after pregnancy.

Observation:

• A 27-year-old woman presented with a focal liver lesion two months postpartum.
• Initial CT interpretation suggested liver cell adenomas.
• The lesion was later identified as choriocarcinoma metastasis.

Findings:

• Choriocarcinoma metastasis can be misdiagnosed as benign liver lesions.
• This highlights the importance of considering rare neoplasms in the differential diagnosis.
• Prompt diagnosis is essential for effective management.

Implications:

• Measuring serum human chorionic gonadotropin (hCG) is recommended for women of childbearing age with focal liver lesions.
• Early detection of choriocarcinoma metastasis can lead to successful treatment outcomes.
• Integrating hCG testing into the diagnostic workup can improve patient care.
