A Case of Biliary Cast Syndrome After Endoscopic and Percutaneous Management of Common Bile Duct Stone.

Biliary cast syndrome is an unusual complication in patients who have previously undergone liver transplantation. It occurs in approximately 5%-18% of such patients. Rare cases of biliary cast syndrome in patients without liver transplants have also been reported.

Fast T2-Weighted Imaging With Deep Learning-Based Reconstruction: Evaluation of Image Quality and Diagnostic Performance in Patients Undergoing Radical Prostatectomy.

Background: Deep learning-based reconstruction (DLR) can potentially improve image quality by reduction of noise, thereby enabling fast acquisition of magnetic resonance imaging (MRI). However, a systematic evaluation of image quality and diagnostic performance of MRI using short acquisition time with DLR has rarely been investigated in men with prostate cancer.

Purpose: To assess the image quality and diagnostic performance of MRI using short acquisition time with DLR for the evaluation of extraprostatic extension (EPE).

Microvascular invasion may be the determining factor in selecting TACE as the initial treatment in patients with hepatocellular carcinoma.

The aim of this study was to investigate factors affecting tumor necrosis with transcatheter arterial chemoembolization (TACE). Factors associated with early hepatocellular carcinoma recurrence after curative hepatectomy were also evaluated.Data of 51 patients who underwent surgery after a single session of TACE at a single university hospital were retrospectively analyzed.

Usefulness of F-FDG PET/CT and Multiphase CT in the Differential Diagnosis of Hepatocellular Carcinoma and Combined Hepatocellular Carcinoma-Cholangiocarcinoma.

Purpose: The purpose of this study was to evaluate the usefulness of multiphasic CT and F-fluorodeoxyglucose (FDG) PET/CT for the differentiation of combined hepatocellular carcinomacholangiocarcinoma (cHCC-CCA) from hepatocellular carcinoma (HCC).

Materials And Methods: From January 2007 to April 2016, 93 patients with pathologically confirmed HCC ( = 84) or cHCC-CCA ( = 9) underwent CT and PET/CT imaging. Contrast enhancement patterns were divided into three types based on the attenuation of the surrounding liver parenchyma: type I (early arterial enhancement with delayed washout), type II (early arterial enhancement without delayed washout), and type III (early hypovascular, infiltrative appearance, or peripheral rim enhancement).

Clinically intractable chronic unilateral hematuria: Successful treatment with renal segmental artery embolization.

Chronic unilateral hematuria (CUH) is characterized by intermittent or continuous gross hematuria that cannot be diagnosed using standard radiology and hematology. The authors report a case of CUH with no discrete lesion at ureteroscopy, successfully treated by selective renal artery embolization. Renal artery embolization could be a treatment option for selected patients with clinically intractable CUH.
