Radiographic findings in the hands in patients with systemic lupus erythematosus.

Hand radiographs of 59 patients with systemic lupus erythematosus (SLE) were examined. Thirty-four revealed radiographic abnormalities, most commonly periarticular soft-tissue swelling or demineralization. Alignment abnormalities, acral sclerosis, avascular necrosis, soft-tissue calcification and terminal tuft resorption were also seen. All patients with periarticular calcification or terminal tuft resorption had Raynaud's phenomenon. Clinical indicators of disease activity (including low serum complement levels) did not correlate with the presence or severity of radiographic abnormalities. Patients with abnormal radiographs generally were older at the time of diagnosis than those with normal studies.

99mTc-pyrophosphate bone imaging in osteopoikilosis, osteopathia striata, and melorheostosis.

Technetium-99m pyrophosphate bone images were contrasted with radiographic findings in two patients with osteopoikilosis, one with osteopathia striata, and one with melorheostosis. Despite the striking radiographic findings, scans were normal in osteopoikilosis and osteopathia striata. In melorheostosis, focal increased radiopharmaceutical accumulation appeared in each radiographically abnormal area. Technetium-99m pyrophosphate bone images should prove helpful when superimposed osseous disease must be differentiated from osteopoikilosis, osteopathia striata, or melorheostosis.

Imaging features of avulsion injuries.

Avulsion injuries are common among participants in organized sports, especially among adolescent participants. Imaging features of both acute and chronic avulsion injuries of the pelvis, knee, ankle and foot, shoulder, and elbow were evaluated to help distinguish these injuries from more serious disease processes such as neoplasm and infection. At radiography, acute injuries (ie, those resulting from extreme, unbalanced, often eccentric muscular contractions) may be associated with avulsed bone fragments, whereas subacute injuries have an aggressive appearance that may include areas of mixed lysis and sclerosis. Chronic injuries (ie, those resulting from repetitive microtrauma or overuse) or old inactive injuries may be associated with a protuberant mass of bone and may bear a striking resemblance to a neoplastic or infectious process. Although not usually required, computed tomography is helpful in the diagnosis if radiographic findings are equivocal or if the injury is not in the acute phase. MR imaging is best suited for the evaluation of injuries to muscles, tendons, and ligaments. Recognition of characteristic imaging features and familiarity with musculotendinous anatomy will aid in accurate diagnosis of avulsion injuries.
