[Multiple calcified cerebral metastases revealing bronchial adenocarcinoma. Apropos of a case].

Calcified brain metastases are rare. They are unique or multiple. The primary site is lung, breast, gastro-intestinal tract, uterine cervix, bone or may be unidentified.

[Computerized tomography-guided needle biopsy for the diagnosis of pulmonary nodules: analysis of a series of 41 patients].

This study was aimed at assessing percutaneous biopsy under computerized tomography (CT) guidance, its results in terms of diagnostic value, factors contributing to its complications or success, and its indications. Results obtained from a series of 41 patients and data from previous clinical trials were compared. Patients who were not eligible due to either poor physical condition or a tumor that could not be reached were not included into the study.

[Value of echography in a case of polyorchidism].

We report a case of polyorchidism diagnosed by scrotal ultrasonography and confirmed by surgery. Sixty eight cases have been reported in the literature.

[Blunt injury of the larynx by hanging. X-ray computed tomographic aspect].

The closed laryngeal traumas by attempt of hanging are rarely studied by medical imaging. The lesions are evaluated by fiberoptic endoscopy and CT scan. We report a case of complicated lesions of the larynx with rupture of the cricothyroid membrane, diagnosed by CT scan and we discuss the usefulness of this technique.

[X-ray computerised tomographic imaging in the diagnosis of intrathoracic kidney].

Two cases are reported of an ectopic right kidney that was partially intrathoracic in position. Diagnosis was simple from CT scan imaging appearances, the examination being performed to investigate an intrathoracic mass. Images showed a tissular mass within a fatty zone in sections without contrast and the typical appearance of the kidney on sections with contrast.
