[Multiple focal liver lesions of a 33 year-old female. Presentation of an unexpected differential diagnosis].
We report the case of a 33 year-old female with a history of 16 years of oral contraception who had been admitted to hospital for further diagnosis of multiple focal liver lesions; laboratory findings showed elevated levels of gamma-GT und AP. Diagnostic procedures showed no primary malignancy as possible reason for metastasis. All further imaging procedures compared with doppler-enhanced ultrasound did not help in diagnosis and lead to inconsistent results. Transcutaneous liver-biopsy showed normal liver histology. In laparoscopic biopsy the result was multifocal adenoma. Because of the rupture risk and potential malignant transformation and no change of sonomorphologic appearance within 12 months a liver-segment resection has been undertaken. Pathology revealed the diagnosis of a multifocal hyperplastic-adenomateous focal-nodular hyperplasia. This case shows that there is no need to use different methods of medical imaging redundantly. We favor a fine-needle double-puncture (lesion and extra-lesion) and tissue examination through an experienced pathologist. A total resection of the lesion is necessary in case of resting uncertainty to characterize its tissue characteristics.
