摘 要：
Heterotopic ossification is the formation of bone in the soft tissues. Soft tissue bone deposition may range from the minimal and inconsequential to massive and clinically significant. In some clinical settings it is a predictable finding with an unpredictable course and in other settings it may be diagnostically confounding. Heterotopic ossification may be encountered in clinically disparate disease processes and circumstances. We review the genetic, neurogenic, post-traumatic, post-surgical and "reactive" causes of heterotopic ossification and discuss some current concepts of its pathogenesis. [References: 60]

摘 要：
OBJECTIVE: To study whether there was a common pattern of clinical symptoms, signs and radiographic features for the dissociation of the polyethylene liner from an acetabular component and to postulate reasons for these features. DESIGN AND PATIENTS: Retrospective study of notes and radiographs of cases of revision hip arthroplasty for polyethylene liner dissociation of the cementless Harris-Galante I porous-coated acetabular component (Zimmer Inc, Warsaw, IN) at the Avon Orthopaedic Centre, Bristol, UK and St. Mary's Hospital, Bristol, UK between 1995 and 2004. Patients were contacted to confirm preoperative symptoms. RESULTS: Nine cases of late polyethylene liner dissociation of this prosthesis have been revised in these institutions. All patients presented with a reduction in mobility, groin pain and limp. Eight patients reported an audible noise on hip movement. In all cases, radiographs showed radiolucency medial to the femoral neck in association with an eccentrically placed femoral head showing contact with the acetabular metal shell, which we have termed the "crescent sign." CONCLUSIONS: There is a typical clinical presentation in this study. The diagnosis can be made from a single anteroposterior pelvic radiograph without the need for previous films for comparison, or the need for arthrography. Clinicians should look specifically for the crescent sign when an eccentrically placed femoral head has been noted, in order to differentiate the more unusual diagnosis of dissociation from that of polyethylene wear. Early revision surgery can prevent damage to the femoral head and metal acetabular shell, thus reducing the complexity of revision surgery.

摘 要：
OBJECTIVE: The purpose of this study is to delineate the magnetic resonance (MR) appearance of a granular cell tumor (GrCT) of the extremity and to correlate the imaging appearance with the microscopic findings. DESIGN AND PATIENTS: A retrospective review of five patients with a histopathologic diagnosis of GrCT and pre-operative MR imaging of the neoplasm was done. The images were reviewed by two musculoskeletal radiologists in a consensus fashion. Lesion location, size, shape, margination, and signal intensity characteristics were assessed. MR findings were correlated with histopathological examination. RESULTS: The benign subtype of GrCT is usually isointense or brighter than muscle on T1-weighted sequences, round or oval in shape, superficial in location, and 4 cm or less in size. On T2-weighted sequences, benign lesions may demonstrate a high peripheral signal, as well as a central signal intensity that is isointense to muscle or suppressed fat. A significant stromal component in the tumor and, hypothetically, a ribbon-like arrangement of tumor cells may influence the signal intensity demonstrated on the T1 and T2-weighted sequences. The malignant subtype may demonstrate signal intensity characteristics and invasion of adjacent structures often seen with other aggressive neoplasms; sizes larger than 4 cm and association with major nerve trunks can be seen. CONCLUSION: Benign GrCT has imaging characteristics which may distinguish this tumor from other soft tissue neoplasms, as well as the malignant type of this tumor.

摘 要：
OBJECTIVE: To assess the diagnostic value of perfusion MR imaging of diseased vertebrae by analysis of three parameters and the distribution of the time-intensity curve (TIC) patterns.DESIGN AND PATIENTS: Dynamic MR imaging was performed on 34 patients with 48 lesions. All lesions were assigned to one of four groups: osteoporotic compression fracture, benign lesion without compression fracture, pathologic compression fracture, or metastatic lesion without fracture. Peak enhancement, steepest slope, and slope value were calculated from the TIC of diseased vertebrae. TICs were classified into five types. Comparisons were made among groups by analysis of the three parameters and the distributions of the TICs pattern.RESULT: All parameters of pathologic compression fracture were significantly higher than those of osteoporotic compression fracture (P<0.05). The steepest slopes of metastatic lesions with and without pathologic compression fracture were significantly higher than those of benign lesions without compression fracture (P<0.05). No characteristic distribution of the TIC pattern helpful for the differentiation of benign and metastatic lesions was found.CONCLUSION: In distinguishing osteoporotic from pathologic compression fractures, semiquantitative analysis of the perfusion MR imaging may be useful. However, the analysis of the TIC patterns can not significantly contribute to the differential diagnosis.

摘 要：
OBJECTIVE: To design a semi-automated program to measure the minimum tibiofemoral joint space width (JSW) of knee radiographs. DESIGN: Bilateral knee radiographs were obtained twice within a 2 week period from 34 asymptomatic research participants. Radiographic images were analyzed to report both the variability of the image analysis program and the reproducibility of JSW measurements within a 2 week period. In addition, the results were compared with minimum JSW measurements read manually by an experienced musculoskeletal radiologist. RESULTS: The variability of the image analysis program was shown to be within one pixel. The results showed that reproducibility was better with the automated method. In addition, the manual method measured a greater minimum JSW than the automated method. There was no significant difference in between-day measurements. There was a significant difference reported between the automated and manual minimum JSW measurements. CONCLUSION: A novel semi-automated method for measurement of JSW has been developed.

摘 要：
OBJECTIVE: To design a semi-automated program to measure minimum patellofemoral joint space width (JSW) using standing lateral view radiographs. DESIGN: Lateral patellofemoral knee radiographs were obtained from 35 asymptomatic subjects. The radiographs were analyzed to report both the repeatability of the image analysis program and the reproducibility of JSW measurements within a 2 week period. The results were also compared with manual measurements done by an experienced musculoskeletal radiologist. RESULTS: The image analysis program was shown to have an excellent coefficient of repeatability of 0.18 and 0.23 mm for intra- and inter-observer measurements respectively. The manual method measured a greater minimum JSW than the automated method. Reproducibility between days was comparable to other published results, but was less satisfactory for both manual and semi-automated measurements. The image analysis program had an inter-day coefficient of repeatability of 1.24 mm, which was lower than 1.66 mm for the manual method. CONCLUSIONS: A repeatable semi-automated method for measurement of the patellofemoral JSW from radiographs has been developed. The method is more accurate than manual measurements. However, the between-day reproducibility is higher than the intra-day reproducibility. Further investigation of the protocol for obtaining sequential lateral knee radiographs is needed in order to reduce the between-day variability.

摘 要：
A middle-aged man was being investigated for constipation. Abdominal radiographs incidentally revealed a large, densely calcified, rounded mass within the pelvic cavity. A CT scan was performed followed by surgical excision with a differential diagnosis of calcified hematoma and an enlarged calcified lymph nodal mass. Histopathological investigation revealed a primary mesenteric extraskeletal osteosarcoma. To the best of our knowledge, a primary extraskeletal osteosarcoma arising from the mesentery has not been described previously in the English literature. The radiological features and differential diagnosis are discussed.

摘 要：
Rosai-Dorfman disease is a rare clinical disorder which may present in many forms. While classically a disease of lymph nodes, soft tissue involvement is fairly common. Soft tissue involvement can occur without any lymphatic or systemic involvement, and may be difficult to diagnose. We describe a patient presenting with multiple soft tissue masses which on biopsy proved to be isolated cutaneous Rosai-Dorfman disease. MR imaging showed two well-defined nonspecific superficial masses that enhanced intensely. Review of the literature suggests that when this disease presents in soft tissue, multiple foci of involvement may be common. Although rare, Rosai-Dorfman disease should be considered in the differential diagnosis of patients presenting with multiple soft tissue masses.
