Pseudarthrosis and pseudopseudarthrosis of ankylosing spondylitis-report of 2 cases.

Pseudarthrosis is a well known, late complication of ankylosing spondylitis associated with extensive discovertebral junction destruction and fracture of the posterior elements. In contrast, the term "Pseudopseudarthrosis" is published in the recent literature to portray similar roentgenologic findings of discovertebral destruction but without bony break of the posterior arch. In this article, each complication is presented by a single case using the demonstration of plain film and computed tomography studies to compare their differences in the posterior spinal elements.

Fluid levels in aneurysmal bone cysts.

Aneurysmal bone cysts are benign, expansile, osteolytic lesions of the bone. All the aneurysmal bone cysts studied in this case report were observed during the 2 year period, 1989 to 1991. The patients involved had received radiographic examination: plain and magnetic resonance (MR) image; one of the patients also received a computed tomography (CT). The plain radiograph generally showed a well-defined, expansile, osteolytic lesion associated with a pathologic fracture; the CT and MR images showed a fluid-fluid level within the lesion. This paper will report the findings of fluid-fluid levels, using radiographic images, in aneurysmal bone cysts.

Arthrographic evaluation of the internal derangement of temporomandibular joint.

From a functional point of view, the temporomandibular joint(TMJ) is one of the most important joints in the body. Optimal radiographic visualization is becoming increasingly important to medical and dental specialists as abnormal TMJ derangements are becoming better understood. Because the most common TMJ arthropathy is the internal derangement of TMJ, arthrography of the temporomandibular joint is widely performed in clinical practice. From January 1986 to December 1990, twenty temporomandibular joint arthrographies were performed in patients with symptoms of pain, clicking and dysfunction. We report our findings on these twenty patients who were examined by arthrography, which was conducted due to internal derangements related to meniscal dysfunction.
