摘 要:
Vascular malformations can be classified into high-flow arteriovenous malformations (AVM) and low-flow venous or lymphatic malformations (VM/LM). VMs and LMs have the ability to cross multiple tissue boundaries. Not only is subcutaneous tissue often involved, but multiple muscle groups, tendons, bone cortex and bone marrow are also not uncommonly violated. Magnetic resonance imaging (MRI) provides valuable information for the assessment and treatment of malformations. Firstly, MRI can characterize the flow pattern of these malformations to guide treatment towards trans-arterial embolization for AVMs and percutaneous embolization for low flow malformations. MRI is essential to define the anatomic extent and involvement of various tissue layers (a distinct advantage over ultrasound), and to correlate treatable components of the malformation with patient symptoms. Treatment is decided by the need to alleviate clinical symptoms, and is dependent on the extent of the malformation as defined by MRI. We present MRI features of vascular malformations to demonstrate the potential spectrum of involvement of these lesions, illustrating the value of MRI in treatment planning. [References: 46]

摘 要:
OBJECTIVES: Although large lesions of the limbs can easily be biopsied without image guidance, lesions in the spine, paraspinal area and pelvis are difficult to target, and benefit from CT guidance to improve the accuracy of targeting the lesion for biopsy purposes. A prospective study of CT-guided core needle biopsies for deep-seated musculoskeletal lesions was conducted at a referral cancer institute over a 4-year period with the aim of assessing the safety and efficacy of the procedure. PATIENTS & METHODS: From January 2000 to December 2003, 136 consecutive CT-guided biopsy sessions were undertaken for musculoskeletal lesions in 128 patients comprising 73 males and 55 females. The following data was recorded in all patients: demographic data, suspected clinicoradiological diagnosis, data related to core biopsy session (date, site, approach, total time required in minutes, number of cores, surgeon satisfaction with adequacy of cores), patient discomfort, complications, histopathology report and number of further sessions if material obtained during the first biopsy session was not confirmatory. The sample obtained during the biopsy session was considered inconclusive if, in the opinion of the pathologist, inadequate or non-representative tissue had been obtained. The diagnosis was considered inaccurate if the final histopathological diagnosis did not match with the biopsy diagnosis, or if subsequent clinicoradiological evaluation at follow up did not correlate with the biopsy diagnosis in those patients who were treated with modalities other than surgery. RESULTS: In 121 patients, a single session was sufficient to obtain representative material, whilst for six patients two sessions, and for one patient three sessions were necessary. The time taken for biopsy, including the pre-biopsy CT examination time, varied from 15 min to 60 min (median 30 min). For 110 bony lesions 116 sessions were required, and for 18 soft-tissue lesions 20 sessions were required. 108 biopsy sessions yielded a diagnosis, whilst 28 were inconclusive (diagnostic yield of 79.41%). Of 108 diagnostic biopsies, five were considered inaccurate (accuracy rate of 95.37%). The overall diagnostic yield and accuracy rate for bony lesions were 81.03% and 95.74%; and those for soft-tissue lesions were 70% and 92.85%. There were two complications with no permanent sequelae. CONCLUSION: CT-guided core needle biopsy is a safe, easy, and effective technique for the evaluation of deep-seated musculoskeletal lesions, with a high rate of diagnostic yield and accuracy. It facilitates definitive therapy without the patient having to undergo a major surgical procedure for diagnosis.

摘 要:
OBJECTIVE: To determine whether the post-harvest magnetic resonance (MR) imaging appearance of flexor carpi radialis (FCR) tendons, harvested during ligamentous reconstruction tendon interposition (LRTI) of the thumb carpometacarpal (CMC) joint arthroplasty, is consistent with tendon regeneration. DESIGN: Operative reports and patient medical records for all patients undergoing LRTI arthroplasty between 1995 and 2003 at our institution were reviewed. MR images of the patients' forearms and wrists were obtained and interpreted by two musculoskeletal radiologists. Using the flexor carpi ulnaris (FCU) tendon as an internal standard, the extent of FCR tendon regeneration was expressed as a percentage by dividing the volume of regenerated FCR tendon by the volume of the FCU tendon. PATIENTS: Fourteen patients who had the full thickness of the FCR tendon harvested and who were available for MR imaging were identified and included in the study. RESULTS AND CONCLUSIONS: At least partial regeneration of the FCR tendon occurred in 11 of the 14 patients (79%). Of these, 2 patients (14%), demonstrated complete, or nearly complete regeneration. Partial regeneration of the FCR tendon was seen in 9 of the 14 patients (64%). In 3 patients (21%), there was no appreciable regeneration of the FCR tendon. Among patients who underwent full-thickness harvest of the FCR tendon for LRTI arthroplasty of the first CMC joint, the follow-up MR imaging appearance of the flexor carpi radialis tendon was consistent with tendon regeneration in 79% of those examined.

摘 要:
OBJECTIVE: To compare six different parameters described in literature for estimation of pelvic tilt on an anteroposterior pelvic radiograph and to create a simple nomogram for tilt correction of prosthetic cup version in total hip arthroplasty. DESIGN: Simultaneous anteroposterior and lateral pelvic radiographs are taken routinely in our institution and were analyzed prospectively. The different parameters (including three distances and three ratios) were measured and compared to the actual pelvic tilt on the lateral radiograph using simple linear regression analysis. PATIENTS: One hundred and four consecutive patients (41 men, 63 women with a mean age of 31.7 years, SD 9.2 years, range 15.7-59.1 years) were studied. RESULTS: The strongest correlation between pelvic tilt and one of the six parameters for both men and women was the distance between the upper border of the symphysis and the sacrococcygeal joint. The correlation coefficient was 0.68 for men (P<0.001) and 0.61 for women (P<0.001). Based on this linear correlation, a nomogram was created that enables fast, tilt-corrected cup version measurements in clinical routine use. CONCLUSION: This simple method for correcting variations in pelvic tilt on plain radiographs can potentially improve the radiologist's ability to diagnose and interpret malformations of the acetabulum (particularly acetabular retroversion and excessive acetabular overcoverage) and post-operative orientation of the prosthetic acetabulum.

摘 要:
PURPOSE: To study the early change of bone matrix and soft tissue around articulation in adjuvant-induced arthritic (AIA) rats non-invasively by X-ray phase-contrast imaging (XPCI), a new imaging method. MATERIALS AND METHODS: Adjuvant-induced arthritis was established in male Sprague-Dawley (SD) rats (n=6, age 40 days) by subcutaneous injection of Freund's complete adjuvant (FCA) into the left hindpaw. In vivo XPCI evaluation of the early soft tissue and bone changes in AIA rats was consecutively performed and correlated with changes in volumes of right hindpaws and body weights. In comparison, the changes in the AIA rats were also evaluated with absorption-contrast imaging using the same X-ray source as XPCI and conventional radiography at the same time. After the imaging evaluation, AIA rats were subjected to histological examination. RESULTS: There was significant difference between the score of XPCI and the other two methods in demonstrating soft tissue (P<0.01), bone details (P<0.01) and lesions (P<0.001). By day 10 after subcutaneous injection of FCA, bone changes in the right hindpaw were not obvious, but swelling of soft tissue appeared. By day 12, bone erosion in the articular facet and the area around the articular facet, was detected, along with osteoporosis, and swelling of soft tissue was aggravated. By day 14 bone erosions became fused and expanded, especially in the margin area around the articular facet. At day 16 bone erosion still existed. Joint interspaces seemed wider than normal, and swelling of soft tissue was significant. By day 18 periosteal new bone formation was seen definitely, destruction of bone decreased, bone density around the articular was enhanced, and swelling of soft tissue was relieved. XPCI could clearly distinguish all these alterations, which could not be demonstrated by absorption-contrast imaging and conventional radiography. During the test period, the volume of the right hindpaw and the body weight of the AIA rats also changed significantly compared with the normal rat. Histological examination confirmed that adjuvant-induced arthritis had occurred in all rats of the adjuvant group. CONCLUSION: Osteoporosis, bone erosion and periosteal new bone formation take place at the early stage of adjuvant-induced arthritis. XPCI can evaluate non-invasively these subtle bone changes that are "blind areas" for conventional radiography.

摘 要:
The pathogenesis of intraneural ganglia remains controversial. Only half of the reported cases of the most common type, the peroneal nerve at the fibular neck, have been found to have pedicles connecting the cysts to neighboring joints detected with preoperative imaging or intraoperatively. We believe that all intraneural ganglia arise from joints, and that radiologists and surgeons need to look closely preoperatively and intraoperatively for connections. Not identifying these connections with imaging and surgical exploration has led not only to skepticism about an articular origin of the cyst, but also to a high recurrence rate after surgery. We present a patient who had two recurrences of a peroneal intraneural ganglion in whom a joint connection was not detected on previous MRIs and operations. Reinterpretation of the original films and high-resolution MRI demonstrated an "occult" joint connection to the superior tibiofibular joint. MR arthrography performed after exercise and 1 h delay, however, clearly showed the connection and communication. The joint connection was then confirmed at surgery through an articular branch. Postoperatively the patient regained nearly normal neurologic function, and follow-up MRI showed no cyst recurrence. MR arthrography with delayed imaging should be considered in cases of intraneural ganglia when a joint connection is not obvious on MRI.

摘 要:
Lipomatosis of nerve, also known as fibrolipomatous hamartoma, is a rare condition of nerve, usually affecting the median nerve. The MRI appearance is characteristic. We describe two cases of lipomatosis of nerve involving the sciatic nerve, an extremely unusual location for this lesion, in patients with sciatic neuropathy. These cases share the typical features previously described in the literature for other nerves, but also contain atypical features not previously highlighted, relating to the variability in distribution and extent of the fatty deposition. Recognition of the MRI appearance of this entity is important in order to avoid unnecessary attempts at surgical resection of this lesion.

Adamantinoma of the long bones is a rare primary bone tumor of uncertain embryogenesis. It tends to involve the tibia almost exclusively. We report on adamantinomas occurring in a 16-year-old male patient, with synchronous tibial and fibular lesions. Histologically, there were characteristic clusters of epithelial cells in a fibrous background, forming a keratin cyst. Immunohistochemically, these cells were strongly positive for cytokeratin. This keratin cyst formation is quite an unusual finding in classic adamantinoma.

摘 要:
A 26-year-old female with a tibial lesion diagnosed as an adamantinoma was treated with intra-lesional curettage, bone grafting and intra-medullary nailing. Six years post-surgery, she presented with an asymptomatic primary site but with a metastatic lesion in the mid-shaft of the ipsilateral femur and lung metastases. The femoral lesion was treated with wide excision and reconstructed with an allograft and plate fixation. Pulmonary metastatectomy was carried out for the lung lesions. A follow-up CT scan of the chest at 1 year after the surgery for the metastatic lesions revealed fresh unresectable bilateral metastases. Although cases of local recurrences and pulmonary metastases in adamantinoma are reported, this case is unusual in presenting without a local recurrence but with simultaneous skeletal and pulmonary metastases.
