ABSTRACT
We report a case of recurrent sacral chordomas that have been successfully controlled by the combination therapy of percutaneous ethanol injection therapy (PEIT) and radiation therapy in a 71-year-old man. PEIT may be one of the adjuvant therapies for recurrent chordomas.

We report a case of spontaneous retroperitoneal hemorrhage caused by rupture of an aneurysm of the right ovarian artery in a 55-year-old woman. Diagnosis was achieved by computed tomography and arteriography. The ruptured aneurysm was treated by transcatheter arterial embolization using microcoils and gelatin sponge particles. This is the first case of rupture of an aneurysm of the ovarian artery not related to pregnancy, and the third case of embolization of a ruptured ovarian artery aneurysm in the literature. We illustrate the usefulness of embolization in treatment of an ovarian artery aneurysm without surgery.

BACKGROUND: To evaluate the findings of altered flow dynamics in the livers of patients with obstruction of superior vena cava (SVC) on helical computed tomography (CT). METHODS: In six patients (age range = 28-80 years) with SVC obstruction, CT findings were retrospectively reviewed to identify the abnormal enhancement patterns of the liver and the relation with the extrahepatic collateral vessels and hepatic vessels. RESULTS: Abnormal hepatic enhancement was observed in the following four (A-D) portions: (A) anterior portion of segment IV (n = 5), (B) subdiaphragmatic portion of the liver (n = 4), (C) posterior portion of the right lobe (bare area; n = 1), and (D) lateral segment of the left lobe (n = 2). Two major collateral pathways to the liver were demonstrated as follows: A and D --> from the umbilical vein to the left portal vein, and B and C --> from the subcapsular vein to the bare area of the liver or to the hepatic veins. On helical CT, these collateral pathways were also clearly visualized. CONCLUSION: When these abnormal enhancements of the liver on CT are recognized within the liver, these findings indicate diversion of contrast material into collateral pathways to the liver with SVC obstruction.
