Novel methods for clinical risk stratification in patients with colorectal liver metastases.

Purpose: Colorectal cancer patients with liver-confined metastases are classified as stage IV, but their prognoses can differ from metastases at other sites. In this study, we suggest a novel method for risk stratification using clinically effective factors.

Materials And Methods: Data on 566 consecutive patients with colorectal liver metastasis (CLM) between 1989 and 2010 were analyzed.

Metastasis versus focal eosinophilic infiltration of the liver in patients with extrahepatic abdominal cancer: an evaluation with gadobenate dimeglumine-enhanced magnetic resonance imaging.

Purpose: To determine the performance of gadobenate dimeglumine (Gd-BOPTA)-enhanced magnetic resonance imaging (MRI) to differentiate focal eosinophilic infiltration (FEI) from metastasis.

Materials And Methods: Gadobenate dimeglumine-enhanced MRI conducted in 38 patients (lesions of 43 metastases and 33 FEIs) with extrahepatic abdominal carcinoma were reviewed retrospectively. Images were divided into 2 sets.

Reliability and validity of the Korean version of Obsessive-Compulsive Inventory-Revised in a non-clinical sample.

Purpose: The reliability and validity of a Korean version of the Obsessive-Compulsive-Inventory-Revised (OCI-R) was examined in non-clinical student samples.

Materials And Methods: The Korean version of OCI-R was administered to a total of 228 Korean college students. The Maudsley Obsessive Compulsive Inventory (MOCI), Beck's Depression Inventory (BDI), and Beck's Anxiety Inventory (BAI) were administered to 228 students.

Radiological and clinical features of sarcomatoid hepatocellular carcinoma in 11 cases.

Objective: To evaluate the imaging and clinical findings of pathologically proven sarcomatoid hepatocellular carcinoma (HCC) in 11 cases.

Methods: We retrospectively reviewed the imaging findings and clinical features of 11 patients with pathologically proven sarcomatoid HCC at 2 university-based tertiary institutions from July 1997 to June 2006.

Results: The most common gross morphologies of sarcomatoid HCC were massive expanding pattern (n = 6 [54%]) or multinodular confluent (n = 5 [46%]) with partial encapsulation (n = 9 [82%]).

Comparison of CT and MRI for presurgical characterization of paraaortic lymph nodes in patients with pancreatico-biliary carcinoma.

Aim: To determine the accuracy of computed tomography (CT) and magnetic resonance (MR) for presurgical characterization of paraaortic lymph nodes in patients with pancreatico-biliary carcinoma.

Methods: Two radiologists independently evaluated CT and MR imaging of 31 patients who had undergone lymphadenectomy (9 metastatic and 22 non-metastatic paraaortic nodes). Receiver operating characteristic (ROC) curve analysis was performed using a five point scale to compare CT with MRI.

Gallstone spillage caused by spontaneously perforated hemorrhagic cholecystitis.

There are occasional incidences of gallstone spillage during laparoscopic cholecystectomy, and there have been frequent reports on such a topic in the literature. To the best of our knowledge, however, there have been no reports about spilled stones caused by spontaneously perforated hemorrhagic cholecystitis. Here, we report the radiologic findings of spilled stones caused by spontaneously perforated hemorrhagic cholecystitis in a 55-year-old man.

Focal eosinophilic necrosis versus metastasis in the liver: the usefulness of two-phase dynamic CT.

Objective: The purpose of our study was to evaluate the usefulness of dual-phase dynamic CT in the differentiation of focal eosinophilic necrosis of the liver and metastasis.

Conclusion: Undetected isoattenuating lesions on arterial phase images that have an indistinct margin, a nonspherical shape, and a homogenous enhancement pattern on portal venous phase images suggest focal eosinophilic necrosis rather than metastasis. Two-phase dynamic CT was found to be useful at differentiating focal eosinophilic necrosis from metastasis.

Early biliary complications of laparoscopic cholecystectomy: evaluation on T2-weighted MR cholangiography in conjunction with mangafodipir trisodium-enhanced 3D T1-weighted MR cholangiography.

Objective: Our aim was to assess preliminary experience with combined conventional T2-weighted and mangafodipir trisodium (MnDPDP)-enhanced T1-weighted MR cholangiography in evaluating early biliary complications of laparoscopic cholecystectomy.

Subjects And Methods: Conventional heavily T2-weighted MR cholangiography with MnDPDP-enhanced T1-weighted MR cholangiography and ERCP were performed in seven patients with high clinical suspicion of biliary complications after laparoscopic cholecystectomy. The final diagnoses of complications were classified according to the presence and degree of bile duct injury, bile leakage, and retained stones.
