The possibilities and limitations of direct digital radiography, ultrasound and computed tomography in diagnosing pleural mesotelioma.

The goal of this study was to compare the possibilities and limitations of direct digital radiography of the chest (DDR), the use of ultrasound of the chest (US) and single slice computed tomography of the chest (CT) in diagnosing pleural mesothelioma. The study was conducted during the course of one year, on 80 patients who were successively referred to a specialized institution, under clinical suspicion of mesothelioma. The method of investigation was the comparison of findings, obtained by the reviewed methods of examination, with the pathohistologic results of a biopsy performed on each patient.

Wegener's granulomatosis of the breast.

Wegener's granulomatosis is a multisystem disorder characterized by necrotizing granulomatous inflammation and vasculitis of small vessels and can affect any organ system. The most common sites of involvement are upper and lower respiratory tracts, and kidneys. Breast involvement is unusual and very rare.

Description of diffuse interstitial lung diseases and assessment of their activity.

Conventional roentgenograms constitute the groundwork for the evaluation of diffuse interstitial lung disease (DILD). ILO classification with its symbols (additionally extended to granulomatoses) does not comprise pathoanatomic assumptions and does not enter lesion genesis for it could lead to diagnostic misconception. "High resolution" computer tomography (HRCT) provides the evaluation of lesion morphology and disease activity.

Chest sonography versus lateral decubitus radiography in the diagnosis of small pleural effusions.

Purpose: The aim of this prospective study was to assess the value of chest sonography in the radiologic diagnosis of small pleural effusions (relative to expiratory lateral decubitus radiography) and to suggest gray-scale sonographic criteria for detecting the presence of small pleural effusions.

Methods: Patients referred for abdominal or chest sonographic evaluation for various reasons were also examined for sonographic features of pleural effusion from May 1, 1997, until January 31, 2000. Patients who had evidence of small pleural effusions were included.
