A 33-year-old woman was admitted because of coma and severe shock. CT-scan of the abdomen showed the presence of multiple liver abscesses associated with a retroperitoneal abscess which were drained percutaneously. A liver biopsy showed diffuse peliosis. After resolution of the abscesses the patient's general condition improved and she could be discharged from hospital. Peliosis hepatis is an uncommon disorder characterized by dilated sinusoids with formation of blood lakes. Many pathogenetic mechanisms and causal agents have been proposed. Liver biopsy is necessary to establish diagnosis. By withdrawing the offending drug or treatment of the underlying disorder, regression may be observed.

A case of idiopathic membranous obstruction of the inferior vena cava (MOVC) is reported. Varicose veins of both lower limbs associated with dermatitis and venous ulceration were the presenting symptoms. Diagnosis was made by cavography after phlebography of both legs had revealed a normal deep system. Ultrasonography demonstrated a 4 mm thick membrane in the inferior vena cava just above the level of the hepatic veins. Stripping of the greater saphenous vein and ligation of incompetent perforating veins was performed to partially correct the venous insufficiency of the most affected limb. The patient refused further treatment of the MOVC. Concise review of the literature. Up to date therapeutic possibilities are discussed.
