Serendipity in scintigraphic gastrointestinal bleeding studies.

A retrospective review of 80 scintigraphic bleeding studies performed with Tc-99m sulfur colloid or Tc-99m labeled red blood cells showed five cases where there were abnormal findings not related to bleeding. In some cases, the abnormalities were initially confused with bleeding or could obscure an area of bleeding, while in other cases, the abnormalities represented additional clinical information. These included bone marrow replacement related to tumor and radiation therapy, hyperemia related to a uterine leiomyoma and a diverticular abscess, and a dilated abdominal aorta (aneurysm). Recognition of such abnormalities should prevent an erroneous diagnosis and the additional information may be of clinical value.

Tarsal navicular stress fractures in runners.

The number of participants in running programs at all levels has increased in recent years. As a consequence, practitioners are more frequently dealing with diagnoses in symptomatic runners. Detection of tarsal navicular stress fractures in long distance runners, including the diagnostic value of radionuclide bone scanning, is discussed.

Dorsal defect of the patella (DDP): a characteristic radiographic lesion.

The dorsal defect of the patella (DDP) is a benign lesion with specific radiographic features. Seven cases of DDP are reviewed; all 7 lesions were identical in location and radiographic appearance. The characteristic lesion is round and lytic, with well-defined margins; it is located in the superolateral aspect of the patella adjacent to the subchondral bone. Arthrography reveals intact cartilage. DDP may occur in both sexes and may be bilateral. It is often found incidentally on radiographs ordered for acute trauma. Its etiology is not known. Differential diagnosis is also discussed.

Enostosis of the spine.

Five patients with single sclerotic vertebral body lesions had serial radiographs demonstrating no change in size of the radiodensities. Radionuclide bone imaging, obtained in 4 of these patients, showed no increased radioisotopic uptake in the areas in question. The absence of growth of the lesions on follow-up radiographs and the presence of negative bone scans support the diagnosis of enostoses of the spine. It is important for the radiologist to realize that benign sclerosis of a single vertebral body may simulate skeletal metastasis.

The adult hip: an anatomic study. Part I: the bony landmarks.

A comprehensive anatomic, pathologic and radiographic study of the adult hip was undertaken to define bony landmarks which, when altered, are reliable indicators of disease. Methodology included radiography of cadaveric specimens and analysis of over 300 anteroposterior (AP) radiographs of "normal" adult hips. This information was applied to clinical situations with the following conclusions: (a) The diagnosis of protrusio acetabuli is warranted if the acetabular line projects medial to the ilioischial line by 3 mm or more in men and by 6 mm or more in women. (b) In acetabular trauma, an AP and two oblique radiographs (30 degrees anterior oblique and 30--45 degrees posterior oblique) are required for complete evaluation. (c) Characteristic alterations in the joint space allow accurate diagnosis of disease.

The adult hip: an anatomic study. Part II: the soft-tissue landmarks.

A comprehensive anatomic, pathologic, and radiographic study was undertaken to define reliable soft-tissue landmarks about the hip. Methodology included an analysis of 300 "normal" adult hip radiographs, tissue maceration, cadaveric intra-articular injection studies and review of selected clinical cases. Results, when applied to clinical situations, indicate: (a) The iliopsoas and "capsular" fat planes are poor indicators of small to moderate amounts of intra-articular fluid in the adult. (b) The "capsular" fat plane is not associated with the joint capsule, but in fact is a fat plane between two muscle bundles anterior to the articulation. (c) Distinct soft-tissue planes are available for dissemination of fluid from the hip joint. These include the iliopsoas bursa, which may distend in association with articular disease, and the fat plane of the obturator externus muscle.

Proximal tibiofibular joint: anatomic-pathologic-radiographic correlation.

An anatomic-pathologic-radiographic study of the proximal tibiofibular joint was undertaken. This synovial articulation between the proximal tibia and fibula may communicate with the knee joint in 10% of adults. Radiography of the normal proximal tibiofibular articulation outlines a consistent relationship between the proximal portions of the tibia and fibula. Disruption of this normal relationship is indicative of anterolateral or posteromedial subluxation or dislocation. Articular disorders of this joint include reheumatoid arthritis and septic arthritis. In the latter, initial alterations of the knee joint may subsequently extend to involve the proximal tibiofibular joint, illustrating the potential communication between these two articulations.

Osteolysis with detritic synovitis. A new syndrome.

A new pattern of osteolysis accompanied by detritic synovitis occurred in a 71-year-old woman. The patient had a severe, destructive, and multilating arthropathy of her hands, with distal phalangeal deformity. Radiographs outlined bone resorption of the appendicular and axial skeleton, with involvement of phalanges, metacarpals, metatarsals, clavicles, long bones, and spine. There was no notable occupational history nor laboratory evidence of hyperparathyroidism. Pathological evaluation revealed synovial ulceration and necrosis, and necrotic bone embedded with fibrotic synovium. This patient's abnormalities appear to represent a new pattern of osteolysis that can be distinguished from other disorders.

Long bone ossifying fibromas.

Ossifying fibromas involving the tibia were seen in two patients. In both patients, the radiographic appearance of the lesions suggested fibrous dysplasia, but histopathologic evaluation demonstrated findings similar to ossifying fibroma of the mandible and facial bones. Radiologic and pathologic recognition of this entity is necessary for proper treatment.
