Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is a useful modality for the precise detection and staging of early prostate cancer.

Background: The aim of this study was to visualize early stage prostate cancer (Cap) in a clinical setting. In previous studies, the results of magnetic resonance imaging (MRI) for screening Cap have rarely been confirmed by well-designed multisite prostate biopsy.

Methods: The prostate glands of 90 men with elevated prostate-specific antigen (PSA) were imaged by dynamic contrast-enhanced MRI (DCE-MRI) before transrectal ultrasound-guided 14-cores prostate biopsy.

Application of serum PSA to identify acute bacterial prostatitis in patients with fever of unknown origin or symptoms of acute pyelonephritis.

Background: Exclusion of prostatitis in screening for prostate cancer (Cap) is a matter of concern in the prostate-specific antigen (PSA) era. Yet, the identification of acute bacterial prostatitis (ABP), intentionally utilizing PSA in patients with pyrexia has been scarcely reported.

Methods: In total, 39 men, who presented at our department with a fever higher than 38.

[High-resolution CT findings of pulmonary atypical adenomatous hyperplasia of 5 mm or less in diameter].

Objective: To clarify the high-resolution CT(HRCT) findings of pulmonary atypical adenomatous hyperplasia (AAH) of 5 mm or less in diameter.

Materials And Methods: We evaluated the HRCT findings of 43 histopathologically confirmed AAH of 5 mm or less in diameter in 7 patients who underwent lobectomy for pulmonary adenocarcinoma. For comparison, we also examined the HRCT findings of 13 bronchioloalveolar carcinomas (BAC) of the same size from these patients.

Microcystic variant of localized malignant mesothelioma accompanying an adenomatoid tumor-like lesion.

The case of a 70-year-old man with a hitherto undescribed pleural mesothelioma is reported. The tumor was localized in the left lung apex and had invaded the parietal pleura. Histologically, the tumor was characterized by a proliferation of epithelioid cells and the formation of microcysts.
