Malignant hepatic epithelioid hemangioendothelioma (HEH) is a rare malignant tumor of vascular origin with unknown etiology and a variable natural course. The authors present a comprehensive review of the literature on HEH with a focus on clinical outcome after different therapeutic strategies. All published series on patients with HEH (n = 434 patients)(More)
OBJECTIVE To compare maximum spatial resolution in multislice computed tomography (MS-CT) and digital subtraction angiography (DSA) using an arterial tree model for canine kidney specimens. METHODS Twenty-three isolated fox terrier kidneys were catheterized with a 4F catheter and underwent contrast-enhanced MS-CT with a maximum spatial resolution of(More)
PURPOSE Usefulness of biexponentially fitted signal attenuation at different b-values for differentiating the histological characteristics of renal tumors. MATERIALS AND METHODS A total of 26 patients with 28 renal masses (histologically proven: 20 clear cell renal cell carcinomas [ccRCC], three transitional cell carcinomas, two oncocytomas, and one(More)
PURPOSE We prospectively evaluated long-term survival in patients with renal cell carcinoma extending to the inferior vena cava. MATERIALS AND METHODS From 1993 and thereafter we followed 86 men and 48 women with a median age of 64 years (range 28 to 86) with renal cell carcinoma and tumor thrombus involvement of the inferior vena cava. Cancer specific(More)
OBJECTIVE The purpose of this study was to evaluate retrospectively the diagnostic value of MRI in the care of patients with suspected scrotal disorders. MATERIALS AND METHODS Testicle-containing scrotal compartments were evaluated by examiners blinded to all clinical information in an interdisciplinary consensus reading after MRI was performed with(More)
OBJECTIVE To evaluate the accuracy of multidetector computed tomography (CT) and magnetic resonance imaging (MRI) in staging and estimating renal carcinomas with caval thrombus. METHODS Initially, 23 patients with suspected caval thrombi were admitted into this prospective study. Triphasic CT imaging was performed using a multidetector CT with a(More)
OBJECTIVES Tumor boards have become an integral part of high-quality cancer care, but in general, patients are not directly involved. To overcome this weakness, we established an interdisciplinary counseling service for renal malignancies where 4 specialists talked to the patient at once. We evaluated this approach from the patients' and physicians'(More)
Complications of embolization and chemoembolization remain a problem even with the development of low-profile catheter material and the introduction of new embolization agents. In recent years many new embolization materials have become available for clinical use, so the possibilities and limitations of these new materials must be understood to allow safe(More)
In this study, we investigated whether assessment of the tumor perfusion by dynamic contrast-enhanced magnetic resonance imaging (DCE MRI) enables to estimate the morphologic grading of renal cell carcinomas. A total of 21 patients with suspected renal cell cancer were examined using a Gadobutrol-enhanced, dynamic saturation-recovery, turbo-fast, low-angle(More)
