High-resolution CT (HRCT) examinations were performed in 22 patients with temporal bone trauma. The CT findings were correlated with the clinical signs and symptoms, routine head CT findings were also examined. HRCT was able to demonstrate fracture lines, ossicular chain disruptions, facial nerve injuries, and hemotympanums in majority of cases. Associated many severe head injuries (brain contusion etc.) were noted in the routine head CT.

A forty-year-old woman who developed brain abscess was found to Rendu-Osler-weber syndrome with multiple arteriovenous fistulas of the left lung. Therapeutic embolization of pulmonary arteriovenous fistulas was performed for the prevention against brain abscess and improvement of hypoxia.

We reviewed the initial emergency-room plain pelvic radiographs of 75 patients with pelvic fracture. In thirty-six patients transcatheter arterial embolization (TAE) was performed for retroperitoneal hemorrhage associated with pelvic fracture (TAE group) and in 39 patients (non-shock group) TAE was not required. ⋯ Specific soft tissue abnormal shadow of TAE group was not present. It may be impossible to determine the necessity of TAE in pelvic fracture on the basis of plain pelvic radiograph.

High resolution computed tomography (CT) was applied to seven patients with hypersensitivity pneumonitis clinically confirmed. The CT findings include; (1) granular pattern with acino-centric distribution, (2) increase in density of haziness in the lung fields, (3) multiform high density areas, and (4) "subpleural curvilinear shadow" localized posteriorly. ⋯ It was especially of interest that the relapsed haziness distributed quite in the same regions. High resolution CT may be an effective adjuvant tool for hypersensitivity pneumonitis when applied to the opportune evaluation through the clinical course.

In order to identify and classify the basic CT appearances of interstitial pneumonia, radiologic -pathologic correlative study was performed using inflated and fixed lungs from autopsy and surgery. The patterns of the abnormalities on the CT images of interstitial pneumonia were classified into 7 categories. ⋯ Based on the result of above study, we analyzed CT of 22 patients with IIP. The lesions which were classified into a hazy density, micronodular densities, confluence of various sized ring like shadows and subpleural bullous changes were frequently recognized together mostly in the periphery of the lung.
