[Metastatic choriocarcinoma in 26-year-old woman--case report].

Gestational trophoblastic tumors are a group of diseases spanning from a benign hydatidiform mole, through an invasive mole to a highly malignant form of choriocarcinoma. Choriocarcinoma is a rare but the most malignant and aggressive neoplasm of all the gestational trophoblastic diseases. It grows rapidly and metastasizes into the lungs, liver, and, less frequently, to the brain. The author presents a case of a 26-year-old woman who was, based on previous investigations, referred for a CT examination for suspected brain tumour. On the basis of medical history provided by the patient's husband, high beta-hCG level and a gynaecological examination, the patient was diagnosed with choriocarcinoma metastasizing into the brain, kidneys and adrenal glands.
