A prospective analysis of 60 patients with gout was undertaken to evaluate the radiographic spectrum of gouty arthritis in patients treated in the era of hypouricemic therapy. Twenty-two of these patients were clinically tophaceous; 36 were considered to have radiographic findings diagnostic of gouty arthritis by strict radiographic criteria. Up to 24% of the patients denied symptoms in joints with radiographic changes of gout; 42% with no evidence of tophi on clinical examination had radiographic changes characteristic of gout. Radiographic assessment can be extremely helpful in the management of gout by documenting the degree and extent of bony involvement, particularly in patients with limited symptoms or without clinical tophi. 相似文献

OBJECTIVE: To explore the typical sonographic features of gray-scale and Power Doppler of acute and chronic gouty arthritis in conjunction with radiographic, clinical, and laboratory findings. MATERIALS AND METHODS: All hand, finger, and toe joints of 19 patients with acute and chronic gout were examined with gray-scale and Power Doppler sonography. The number and size of bone changes detected with sonography was compared to radiographic findings. Vascularization of the synovial tissue was scored on Power Doppler (grades 0-3), and was compared with clinical appearance, including swelling, tenderness, and redness (grades 0-3). RESULTS: In acute gout, mild to moderate echogenic periarticular nodules with sonotransmission and hypervascularization of the edematous surrounding soft tissue were found. In chronic gout, tophaceous nodules completely blocked transmission of US wave, leading to strong reflexion and dorsal shadowing in a minority of cases. No significant difference in the detection of large bone changes (>2mm) was found between sonography and radiography. However, gray-scale sonography was significantly more sensitive in the detection of small bone changes (p<0.001). Power Doppler scores were statistically significantly higher than clinical examination scores (p<0.001). DISCUSSION: Sonography is superior to radiographs in evaluating small bone changes. The inflammatory process in joints can be better detected with Power Doppler sonography than with clinical examination. Typical sonographic appearance of acute and in particular of chronic gout might provide clues on gouty arthritis that adds to the information available from conventional radiography, clinical, and laboratory findings. 相似文献

Recently gout has been recognized as a cause of inflammation in patients with nodal osteoarthritis. We reviewed the clinical
data and radiographs of four patients with known osteoarthritis of the interphalangeal joints of the hands who developed gout.
Radiographic changes of osteoarthritis in the affected interphalangeal joint were present in all four patients. In our cases,
radiographic findings were typical of gout in one patient, including the presence of large eccentric soft tissue masses and
periarticular erosions. In three patients, radiographic findings were non-specific, including only a small eccentric nodule
in one patient, diffuse soft tissue swelling in a second, and a large calcified soft tissue mass with bony erosions in a third.
Whenever a patient with interphalangeal joint osteoarthritis presents with an acute episode of inflammation the possibility
of gout should be considered. Recognition of gout will allow the timely initiation of appropriate therapy. 相似文献

We present the case of a 60-year-old man with a history of severe tophaceous gout with polyarticular involvement who came to the emergency room due to direct trauma to the right forearm and knee. The knee X-ray and CT scan showed a lateral tibial plateau fracture characterized by the presence of a lytic bone lesion. The presence of a solid neoplasm was ruled out and a CT-guided biopsy was performed. Histological evaluation revealed findings typical for an advanced intraosseous gout. As there was no significant risk of progression of the lytic lesion, the fracture site was treated conservatively. This case is unique in the literature in terms of location and should be considered as an atypical site of intraosseous gout. Proper differentiation of a pathological fracture on an intraosseous gout location from a neoplastic lesion is essential to choose the correct therapy. 相似文献

Objective: To describe radiographic features of gout that may mimic infection.
Design and patients: We report five patients with acute bacterial gout who presented with clinical as well as radiological findings mimicking
acute bacterial septic arthritis or osteomyelitis. Three patients had delay in the appropriate treatment with the final diagnosis
being established after needle aspiration and identification of urate crystals under polarized light microscopy. Two patients
underwent digit amputation for not responding to antibiotic treatment and had histological findings confirming the diagnosis
of gout.
Conclusion: It is important for the radiologist to be aware of the radiological manifestations of acute gout that can resemble infection
in order to avoid inappropriate diagnosis and delay in adequate treatment. The definitive diagnosis should rely on needle
aspiration and a specific search for urate crystals.

The aim was to compare X-ray and ultrasound (US) in diagnosing gout. In a prospective study, 105 consecutive patients with
clinical suspicion of gout underwent conventional X-ray und high-resolution US in order to help in arriving at a definite
diagnosis. X-ray findings suggestive of gout included soft-tissue opacifications with densities between soft tissue and bone,
articular and periarticular bone erosions, and osteophytes at the margins of opacifications or erosions. US findings suggestive
of gout included bright stippled foci and hyperechoic soft-tissue areas. Fifty-five patients had a definite diagnosis of gout
(102 involved sites), 31 patients were diagnosed as having another disease (59 involved sites), and 19 patients were excluded
from the study because a definite diagnosis could not be established. X-ray suggested gout with a sensitivity of 31% (32/102)
and a specificity of 93% (55/59), whereas US suggested gout with a sensitivity of 96% (98/102) and a specificity of 73% (43/59).
US was much more sensitive than conventional X-ray but less specific. Our data show that US often provided additional diagnostic
information in patients with clinical suspicion of gout when laboratory findings and X-ray results were negative or inconclusive
and should therefore be used in these cases. 相似文献

The role of bone scintigraphy in osteogenic sarcoma 总被引:2,自引:0,他引:2
Hospital records of 27 children with osteogenic sarcoma were reviewed in an effort to define the usefulness of skeletal scintigraphy in the initial evaluation and follow-up of their disease. Serial bone scans as well as plain radiographs, linear tomograms, and computed tomograms were evaluated for evidence of bone or lung metastases. Eighteen patients developed lung metastases and three developed bone metastases. Seven patients demonstrated uptake of tracer in lung metastases, however, the lesions were all easily identifiable by radiographic means. All bone metastases were detected by scintigraphy, in one instance prior to radiographic abnormality. In no cases were bone metastases known to occur in the absence of lung metastases. None of the bone scans performed for routine follow-up pruposes resulted in altered therapy for the patient. We propose that skeletal scintigraphy is useful in the initial metastatic work up of osteogenic sarcoma, and may be helpful in some patients with specific indications during their follow-up, but is less valuable when there is no clinical suspicion for bone metastases. 相似文献

Isolated or dominant osteolytic lesions of the patella are an unusual manifestation of gout. We present seven patients who had such patellar lesions unilaterally (six patients) or bilaterally (one patient) and analyze the radiologic characteristics to determine whether they can be differentiated from those of other osteolytic lesions of the patella. The lesions were uniformly characterized by a geographic pattern of bone destruction in the superolateral aspect of the patella. Five lesions were each accompanied by a peripatellar soft tissue mass, four of which contained calcification. It therefore appears that an osteolytic lesion of the superolateral portion of the patella, especially when associated with a peripatellar calcified soft tissue mass, should alert one to the possible diagnosis of gout. Awareness of this possibility may obviate the need for invasive diagnostic procedures. 相似文献

The spectrum of radiographic abnormalities accompanying bone and joint infection that results from human bites of the hand is presented in an analyis of 13 patients. Features include mono-articular involvement, predilection for a metacarpophalangeal joint, soft tissue swelling, joint space narrowing, bone erosions and periostitis. Magnification techniques may be required for early and accurate diagnosis. 相似文献

Chronic tophaceous gout is a common disease but rarely found in the head and neck region. Here we report a case of a middle aged male who presented with a mass over the right side of the nasal bridge. CT of the paranasal sinuses revealed a tophi lesion in the right nasal bridge with erosion of the underlying nasal bone. The mass was excised and histologically confirmed to be a gouty tophus. This case report illustrates how a common disease presented in an uncommon location could pose a diagnostic challenge. 相似文献

The radiographic features of 42 purely lytic osteosarcomas are presented. Purely lytic osteosarcoma is identified as a lytic lesion of bone with no demonstrable osteoid matrix by conventional radiographic modalities. Purely lytic osteosarcoma represented 13.7% of a group of 305 osteosarcomas. The most common presentation was that of a lytic illdefined lesion with a moderate to large extraosseous mass component. Nine lesions presented with benign radiographic features. The differential diagnosis is outlined. The need for awareness of this type of presentation of osteosarcoma is stresssed. 相似文献

Bone infarction of the distal femur is reported in two patients with osteosarcoma of the leg (1 tibia, 1 fibula) treated by preoperative chemotherapy including intraarterial chemotherapy (IAC) by Cis-platinum.Both patients were examined by magnetic resonance imaging before chemotherapy and again prior to limb salvage surgery.The location of these lesions in the distal femur must suggest bone infarction especially if the tumor has decreased in size under treatment. 相似文献

Fifty-nine cases of lesions presenting in the patella were identified after review of the databases of four European bone
tumour registries. Of the 59 cases, 46% were non neoplastic, 39% were benign and 15% were malignant. The commonest benign
neoplasm was giant cell tumour (GCT) (11 cases). Younger patients were more likely to have a benign neoplasm. Lesions in patients
less than 40 years of age included giant cell tumour, chondroblastoma, aneurysmal bone cyst (ABC), osteomyelitis, osteoid
osteoma and solitary bone cyst. In patients older than 40 years, the following were common lesions: intra-osseous gout, metastasis
and intra-osseous ganglion. Expansion of the patella with thinning of cortex was seen more commonly in GCT and brown tumour
in hyperparathyroidism. There was associated soft tissue extension in gout and malignant lesions. 相似文献

Tophaceous gout causing cord compression with a normal serum urate level and with no current symptoms of polyradiculopathy
is a rare occurrence. We describe the computed tomographic (CT) findings of large, well-defined marginal and juxtamarginal
erosions containing urate deposits which resulted in extradural cord compression in the cervical spine of a patient with chronic
polyarticular tophaceous gout. 相似文献
