[Focal liver lesion after normal pregnancy].

Two months after a normal pregnancy, a 27-year-old woman presented with a focal liver lesion, which was first interpreted on CT as 'multiple liver cell adenomas'. 2 months later, it turned out to be a metastasis of a choriocarcinoma. This rare neoplasm will often be omitted from the differential diagnosis of liver lesions found during or after pregnancy. However, it is important not to miss this diagnosis since choriocarcinoma metastasis can be successfully treated. Therefore, it is advisable when focal liver lesions are found in women of child-bearing age also to measure human chorionic gonadotropin (hCG) serum concentration.
