Metástases cerebrais ocorrem em 10 a 20% das pacientes com coriocarcinoma. Apresentamos o décimo segundo relato na literatura mundial de paciente com aneurismas oncóticos, demonstrados na angiografia cerebral, secundários a metástases cerebrais de coriocarcinoma. A importância de se considerar esta patologia no diagnóstico dias lesões expansivas e/ou hemorrágicas cerebrais numa paciente em idade reprodutiva é salientada, bem como as características laboratoriais e radiológicas. O papel da quimioterapia, cirurgia e radioterapia no manuseio dessas metástases é discutido.

Cerebral metastasis occur in 10 to 20% of patients with choriocarcinoma. We describe the twelfth patient with oncotic aneurysms from choriocarcinoma verified by cerebral angiography. The importance to consider this disease in a woman of childbearing age who develop an intracerebral hemorrhage or a lesion with mass effect is emphasized, as well as laboratorial and radiological characteristics. Therapeutic approaches with chemotherapic agents, surgery and irradiation are discussed.

The bases and technical cares for the neuro-radiological study of the aorto-cervical and spinal vessels employing the retrograde catheterization according to Seldinger technic and with the Odman-Ledin catheters are reported. The authors recommend type II neuroleptanalgesia as anesthesical sedative and the use of percutaneous punction of the femoral artery or, by choice, of the axilar or humeral artery. For the selective catheterization by femoral via, they make previously an aortography, in order to know the anatomy of the supra-aortic vessels, with control through the image-inten-sifier or fluoroscopy. They employ manual injection for the study of the supra-aortic vessels and a Gidlung injector for the contrast of the ascending aorta. Complications are discussed.
