Objectives: We evaluated the relationship between 1) anatomic variations of the middle turbinate and bony septal deviations and 2) chronic sinusitis.

Methods: We compared 73 computed tomographic scans of healthy control patients with 461 scans performed for evaluation of nasal symptoms. Paranasal sinusitis was identified.

Acute phlegmonous infection of the gastrointestinal tract is characterized by purulent inflammation of the submucosa and muscular layer with sparing of the mucosa. The authors report a rare case of acute diffuse phlegmonous esophagogastritis, which was well diagnosed based on the typical chest computed tomographic (CT) findings and was successfully treated. A 48-yr-old man presented with left chest pain and dyspnea for three days.

Introduction: A hepatic subcapsular hematoma in a neonate shows a non-specific presentation such as the presence of an abdominal mass without symptoms of hemorrhage and is clinically less distinguished as compared to cases detected during an autopsy.

Case Presentation: A neonate was delivered by vaginal delivery after 29 weeks and three days gestation with breech presentation. In a laboratory study, there were slightly increased levels of liver enzymes but the platelet count and hemoglobin level were normal.

A 67-year-old woman with end-stage renal disease presented with profound edema of both breasts. The presence of a patent hemodialysis basilic transposition fistula and superior vena cava obstruction (SVC), due to fibrosing mediastinitis, was demonstrated by the use of fistulography. Endovascular treatment with a balloon and stent caused immediate resolution of the breast edema.

Background: Accurate evaluation of local extent in bladder cancer is important to determine the optimal therapeutic strategy and to predict the outcome of treatment. The purpose of this study is to evaluate the accuracy of 3D volumetric reconstructed US in the assessment of tumor detection and serosal invasion in patients with bladder cancer.

Methods: A total of 14 patients with findings of bladder cancer determined with the use of cystoscopy was examined with the use of bladder two-dimensional (2D) US and subsequent 3D US.

A mucinous carcinoma of the breast is a well-differentiated rare histological type of invasive ductal carcinoma, having a lower frequency of metastasis to an axillary lymph node and a better survival rate. Bilateral breast cancer has an overall incidence of 4% to 20% in patients with primary operable breast cancer. Few reports exist in the clinical literature characterizing a synchronous bilateral mucinous carcinoma of the breast.

Overexpression of cyclooxygenase-2 (COX-2) has been associated with hepatocarcinogenesis. Inhibitors of COX-2 have proapoptotic and antiproliferative effects on malignant tumors and inhibit tumor invasion to the surrounding tissues. We report here a case of complete regression of advanced hepatocellular carcinoma (HCC) during COX-2 inhibitor administration.

Objective: We wanted to describe the retrospective CT features of subtle pleural metastasis without large effusion that would suggest inoperable lung cancer.

Materials And Methods: We enrolled 14 patients who had open thoracotomy attempted for lung cancer, but they were proven to be inoperable due to pleural metastasis. Our study also included 20 control patients who were proven as having no pleural metastasis.
