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.

Computed tomography with multiplanar reconstruction of acetabular fractures.

Computed tomography of acetabular fractures, using 3 mm thick continuous slices, was routinely supplemented with reformatted images in the coronal and sagittal plane. We have found this to be helpful in the preoperative evaluation of our cases for insight into these often complex fractures. Three representative case reports are presented.

Digital subtraction arthrography of hip joint prostheses.

Digital subtraction arthrography (DSA) was performed in 14 patients in the evaluation of painful hip prostheses. Information about component loosening seems to be as reliable as with conventional arthrography. The examination time is very short, and results are immediately available. Electronic image manipulation allows the examiner to produce optimal picture quality.

High-resolution CT and air CT cisternography in the diagnosis of acoustic neuromas.

High-resolution thin-section computed tomography (CT) is helpful in determining the real extent of large acoustic neuromas by means of multiplanar reconstructions. High-resolution CT has to be performed early in the work-up of any patient suspected of acoustic neuroma. Small acoustic neuromas, however, can easily be overlooked because a high percentage of these tumors has an almost isodense appearance (54%), and because 53% enhances after intravenous contrast injection. High-resolution air CT cisternography has to be considered the method of choice for the detection or exclusion of small acoustic neuromas. This procedure also demonstrates ingrowth of the tumor into the neurovascular bundle.
