摘 要：
Vascular malformations and tumors comprise a broad spectrum of lesions that can cause significant morbidity and even mortality in children and adults. Classification of vascular malformations into high flow and low flow has significant impact on management since the main treatment of the former is transarterial embolization and the later percutaneous sclerotherapy. Magnetic resonance imaging (MRI) is a noninvasive effective tool for imaging and classification of vascular malformations based on the presence of lobulated masses, signal voids, and hemodynamic flow characteristics. MRI also provides details about anatomic extent of the lesion, proximity to vital structures, and involvement of multiple tissue planes. The prototype of vascular tumors is infantile hemangioma with its typical involution after a proliferative phase during infancy. Hemangioma appears as a distinct intensely enhancing soft tissue mass with enlarged feeding arteries and draining veins. Less common vascular tumors include congenital hemangioma, kaposiform hemangioendothilioma, angiolipoma, angiosarcoma, and hemangiopericytoma.

摘 要：
A radiograph is often the first investigation to be requested when a patient presents with limb pain or a mass. Whilst we do not advocate that this is the only investigation to be employed in the evaluation of such patients, a working knowledge of the variety of abnormal findings that can present in the soft tissues on radiographs remains useful. We reviewed the radiographic findings of soft tissue masses from a prospectively compiled database of all such lesions presenting to a specialist orthopaedic oncology service over the past 8 years. Of the cohort of 1,058 individuals with a proven soft tissue tumour, 454 had had a radiograph taken of the affected area. Of these, 281 (62%) patients had a positive radiographic finding. The most common findings were a visible soft tissue mass (n = 141), the presence of calcification (n = 76), fat (n = 32) and evidence of bone involvement (n = 62). More than one finding was sometimes present in the same patient. These findings were present in both benign and malignant tumours. This review article describes the incidence and diagnostic relevance of these plain film findings for suspected soft tissue tumours.

摘 要：
OBJECTIVE: A prospective study was conducted to determine the accuracy of routine magnetic resonance (MR) imaging in correctly identifying subchondral fracture in avascular necrosis of the femoral head without apparent focal collapse on standard radiographs. MATERIALS AND METHODS: Spiral computed tomography (CT) with coronal and sagittal reformations and routine MR imaging with spin-echo T1WI and fat-suppressed spin-echo T2WI coronal, axial, and sagittal images were performed in 28 hips of 25 patients (M/F = 20:5; age 16-76 years) suffering from early-stage avascular necrosis of the femoral head on standard radiographs. The MR images were reviewed by a musculoskeletal radiologist and a general radiologist in blinded fashion. Using CT as the standard of reference, the accuracy of MR imaging in diagnosing subchondral fractures in avascular necrosis was evaluated. RESULTS: When the diagnoses of the two readers were compared with each other, only 16 of the 28 diagnoses (57.5%) agreed. Seventeen of the 28 MR imaging readings (60.7%) made by the musculoskeletal radiologist and 15 of the 28 (53.5%) made by the general radiologist agreed with those of the CT standard. False-positive diagnosis (that is, diagnosis of fracture when no fracture could be seen on CT) was more common than false-negative diagnosis. CONCLUSIONS: The accuracy of routine MR imaging in the evaluation of subchondral fracture is not satisfactory. False-positive diagnosis is not uncommon. Interpretation of routine MR imaging readout should be guarded.

摘 要：
OBJECTIVE: The vascular status of femoral heads in the post-traumatic period of intracapsular femoral neck fracture (ICFNF) remains uncertain until the patient actually develops avascular necrosis (AVN). Several methods for predicting the viability of femoral head have been reported, that are not effective or widely used because of unreliability, potential complications, and technical difficulties. The present study involved the use of Dynamic MRI (DMRI) in assessing femoral head vascularity to predict AVN. MATERIALS AND METHODS: The role of DMRI was studied prospectively in 30 patients with 31 ICFNF. Fractures were divided in to three types (Type A, B, or C) based on the femoral head vascularity shown by dynamic curve patterns on MRI evaluation. Type A was preserved vascularity, Type B was some decrease in vascularity but still viable while Type C was significantly reduced vascularity. These were followed-up for 6 months to 2 years to observe the final outcome in terms of union, non-union, or AVN. RESULTS: We found that Type A curves correlate well with vascular status and Type C curves correlate well with poor vascularity of the femoral heads. No AVN was seen in any of Type A (13/31) or Type B (eight out of 31). Five cases showed AVN and all of them were of Type C dynamic curves. CONCLUSION: Dynamic MRI is a reliable tool to evaluate vascularity of femoral heads and thus reduces the uncertainty of outcome of treatment of ICFNFs. DMRI can be a useful tool to formulate a treatment algorithm in management of ICFNF.

摘 要：
OBJECTIVE: The authors describe magnetic resonance (MR) findings in eight patients with histologically confirmed focal myositis. MATERIALS AND METHODS: In each patient, axial TSE T1-weighted and fast short-tau inversion recovery (STIR) images were obtained using a 1.5-T MR scanner. Three patients also underwent dynamic contrast-enhanced MR examination using a GE T1-weighted sequence. The following features were evaluated: anatomical distribution, extent of the involvement, signal intensity characteristics, dynamic enhancement pattern and outcome at follow-up examinations. RESULTS: Seven of eight lesions were located in the lower extremities, one of eight in the arm; four of eight involved part of a muscle, two of eight diffusely involved a muscle and two of eight showed multifocal involvement of two or more muscles. All lesions were hyperintense on fast-STIR images: the hyperintensity was homogeneous in six of eight and inhomogeneous in two of eight. On T1-weighted unenhanced images, all lesions but two appeared isointense or slightly hypointense in comparison to normal muscles; two lesions showed a slight hyperintensity. Dynamic enhancement pattern corresponded to the type usually seen in benign soft tissue lesions. All lesions disappeared. CONCLUSION: Focal myositis is an uncommon pseudotumour which should be considered in the differential diagnosis of muscular masses and myopathies.

摘 要：
PURPOSE: The purpose of this study was to describe the prevalence and imaging appearance of radiation induced pseudotumors in patients following radiation therapy for extremity soft tissue sarcomas. MATERIALS AND METHODS: We retrospectively reviewed the serial magnetic resonance (MR) images of 24 patients following radiation therapy for extremity soft tissue sarcomas. A total of 208 exams were reviewed (mean, 8.7 exams per patient) and included all available studies following the start of radiation therapy. Exams were analyzed for the identification of focal signal abnormalities within the surgical bed suggesting local tumor recurrence. Histopathologic correlation was available in nine patients suspected of having local tumor recurrence. Additional information recorded included patient demographics, tumor type and location, radiation type, and dose. RESULTS: The study group consisted of 12 men and 12 women, having an average age of 63 years (range, 39-88 years). Primary tumors were malignant fibrous histiocytoma (n = 13), leiomyosarcoma (n = 6), liposarcoma (n = 3), synovial sarcoma (n = 1), and extraskeletal chondrosarcoma (n = 1). All lesions were high-grade sarcomas, except for two myxoid liposarcomas. Average patient radiation dose was 5,658 cGy (range, 4,500-8,040 cGy). Average follow-up time was 63 months (range, 3-204 months). Focal signal abnormalities suggesting local recurrence were seen in nine (38%) patients. Three of the nine patients with these signal abnormalities were surgically proven to have radiation-induced pseudotumor. The pseudotumors developed between 11 and 61 months following the initiation of radiation therapy (mean, 38 months), with an average radiation dose of 5,527 cGy (range, 5,040-6,500 cGy). MR imaging demonstrated a relatively ill-defined ovoid focus of abnormal signal and intense heterogeneous enhancement with little or no associated mass effect. CONCLUSION: MR imaging of radiation-induced pseudotumor typically demonstrates a relatively ill-defined ovoid mass-like focus of intense heterogeneous enhancement with little or no associated mass effect. Imaging follow-up or biopsy may be an alternative course of action to surgical re-exploration if this diagnosis is considered. The study revealed radiation-induced pseudotumor in 12.5% of patients in our extremity study group, suggesting that radiation-induced pseudotumor may be more prevalent than previously reported.

摘 要：
OBJECTIVE: Classical Poland syndrome is represented by unilateral aplasia of the sternocostal head of the pectoralis major muscle and ipsilateral simple syndactyly and brachydactyly. Various classifications of the severity of hand involvement have been proposed. Since its initial description, numerous studies have been made of the bony, soft tissue, organ, and hematological disturbances. However, carpal bone involvement has been largely overlooked. The purpose of this study was to evaluate the carpal bones in patients with Poland syndrome from a local (Manitoba) cohort as well as those from the literature. MATERIALS AND METHODS: Hand radiographs from local patients and cases identified from the literature with confirmed Poland syndrome were examined for evidence of carpal bone involvement. Only cases with radiographs of adequate quality were included in the analysis. Clinical information (including gender and age) was necessary for evaluation of bone maturation. In total, seven local patients and 23 patients from the literature were evaluated. Ethics approval for study of the local patients was obtained by the Research Ethics Board of the University of Manitoba. RESULTS: Of the 23 literature patients, 12 patients (52%) had abnormal findings. Of the abnormal patients, four of 12 (33%) had carpal fusions, eight of 12 (67%) showed disharmonious ossification between the carpal and tubular bones and seven of 12 (58%) showed delay of carpal ossification. Of the local cohort, three patients were too young to characterize carpal involvement. Of the four remaining patients, two (50%) had abnormal carpal morphology, three out of four had disharmonious ossification and all four had delay of ossification of carpal bones. Carpal fusions, particularly of the scaphoid and trapezium, were common in both groups. CONCLUSION: Carpal bone anomalies (delay, disharmony, and/or fusions) are frequent in Poland syndrome and can occur in patients with either mild or severe hand involvement. Imaging of the unaffected hand is helpful in determining the extent of carpal findings.

摘 要：
The observation of a bubble of gas at the most non-dependent margin of a lytic bone lesion which has sustained a pathologic fracture implies that the lesion is hollow and can assist the radiologist in making the diagnosis of a unicameral bone cyst. The imaging studies of two patients who sustained pathologic fractures through unicameral bone cysts and exhibited the "rising bubble" sign are shown. The sign's basis, proper utilization, and potential pitfalls are discussed.
