    Notes: Abstract. Peliosis hepatis is an uncommon liver condition characterized by blood-filled cavities. We report the CT, angiographic and MR features of a case of peliosis hepatis with no obvious etiology and spontaneously regressing hemorrhagic necrosis. Helical CT showed multiple peripheral low-density regions with foci of spontaneous high density suggesting the presence of blood component. On MR imaging, the multiple peripheral lesions were hypointense on T1-weighted and hyperdense on T2-weighted images, with bright foci on all sequences suggesting subacute blood. Angiography showed no evidence of tumor or vascular malformation; multiple nodular vascular lesions filling in the parenchymal phase and persisting in the venous phase suggested blood-filled cavities. Pathological examination showed blood-filled spaces with no endothelial lining, characteristic of the parenchymal type of peliosis. Knowledge of the imaging features of hemorrhagic necrosis due to peliosis hepatis is important since it can be responsive to antibiotic therapy. Furthermore, differentiating hemorrhagic necrosis from hepatic abscess avoids dangerous and sometimes fatal percutaneous drainage.

    Description / Table of Contents: Résumé. Les auteurs rapportent vingt-neuf cas de tumeurs à cellules géantes (TCG) malignes dont le suivi s’étalait de 6 mois à 18 ans. Dix-sept étaient malignes d’emblée et douze le sont devenues lors de la récidive d’une TCG initialement bénigne. La clinique de ces tumeurs diffère peu de celle des TCG bénignes, hormis la plus grande fréquences des localisations du tibia distal et du sacrum. Nous avons inclus dans cet étude les TCG dédifférenciées car leur aspect clinique, radiographique et leur pronostic est similaire aux TCG grade III, nous avions dix-huit TCG grade III et douze TCG dédifférenciées. Le but de cet travail était de tenter de mettre en évidence l’intérêt de la chimiothérapie dans le traitement de ces tumeurs malignes, pour cela trois groupes de patients ont étéétudiés en fonction de leur traitement: chirurgie seule, chirurgie et chimiothérapie, et radiothérapie seule. Le pronostic de ces tumeurs est mauvais avec un taux de survie à 5 ans qui est de 50% dans notre série. Nous n’avons pas mis en évidence de différence statistiquement significative entre les TCG d’emblée malignes et celles devenues malignes secondairement, il n’y a pas non plus a différence de survie entre les TCG grade III et les TCG dédifférenciées. Dans le groupe des patients traités par chirurgie et chimiothérapie, le taux de survie à un an est supérieur à celui des autres groupes (test du chi 2 ), par contre la comparaison des courbes de survie (par le test du Log Rank) et de la survie à cinq ans (test du chi 2 ) ne met pas en évidence de différence significative entre les groupes traités avec et sans chimiothérapie. La chimiothérapie néo-adjuvante semble avoir un intérêt dans le traitement de ces tumeurs malignes. L’efficacité de ce traitement devra cependant être confirmée par une étude sur une plus grande série de patients.
    Notes: Summary. Twenty-nine patients with malignant giant-cell tumours of bone (GCT) were followed- up for between 6 months and 18 years. Seventeen of the tumours were primary and 12 were due to malignant degeneration of initially benign lesions. The clinical features did not differ from those of benign GCT, except for a higher incidence in the distal tibia and sacrum. Anaplastic GCTs were included in the study because their clinical and radiographic features and prognosis were no different from those of the GCT grade III of Jaffe. Eighteen of the tumours were grade III, and 11 were anaplastic. This retrospective study was intended to assess the effects of chemotherapy and surgery for malignant GCT. Three treatment groups were selected, in which treatment was either by surgery alone, surgery plus chemotherapy, or radiotherapy alone. – The prognosis was poor and the 5 year tumour-free survival rate in the series was 50%. The prognosis was the same for primary as for secondarily malignant tumours. There was no statistical difference in survival between malignant grade III and anaplastic malignant tumours. The one-year survival rate for patients treated by chemotherapy and surgery was statistically higher (chi 2 test) than for persons treated by surgery alone. However, the five-year survival rate and the actuarial survival curves were not statistically different in the two groups (log rank test). – Chemotherapy appears to be of some value in the treatment of these malignant tumours but a larger series is required to confirm the efficacy of this approach.
