Computed tomography of pleural hyaloserositis.

Pleural hyaloserositis is an uncommon finding on routine chest X-rays. The images may simulate metastatic lesions. Four cases of pleural hyaloserositis are described in which computed tomography (CT) demonstrated calcified pleural pseudotumors.

Psoas abscess and giant fistula twenty-one years after nephrectomy.

Vague abdominal complaints and low back pain are common in modern medicine. We describe the case of a patient who presented these symptoms twenty-one years after a nephrectomy accompanied by persistent elevated erythrocyte sedimentation rate for unknown reason. CT and fistulography showed a psoas abscess and a giant fistula.

Xanthogranulomatous pyelonephritis: comparison of extent using computed tomography and magnetic resonance imaging in one case.

In a case of diffuse xanthogranulomatous pyelonephritis, computed tomography (CT) and magnetic resonance (MR) were used. The MR proved to be more precise in the preoperative evaluation of inflammatory extension to the spleen and into the abdominal wall. The CT was more accurate in excluding spread to the colon.

Percutaneous transluminal angioplasty during operation.

In certain cases it can be useful to perform percutaneous transluminal angioplasty (PTA) and vascular surgery in the same session. The PTA procedure has to be performed by the radiologist through an artery that has been prepared and visualized by the vascular surgeon. This combined procedure usually lessens the number of hospitalization days and offers the patient the advantage of being cured in one session.
