[Hypermobile snapping medial meniscus: features on flexion-extension MRI].

We report 3 cases of snapping medial meniscus due to hypermobility confirmed on extension and flexion MR imaging. The anterior horn of the medial meniscus was anteriorly subluxed during extension with reduction during flexion. Analysis of our imaging data and a review of the literature confirm that this relates to hypermobile medial meniscus, an anatomical variant.

[Non traumatic high flow priapism: arterial embolization treatment].

Purpose: To report cases of non traumatic high flow priapism treated by arterial embolization.

Material And Methods: Six men presented with non traumatic high flow priapism, the diagnosis was based on colour Doppler ultrasound, cavernous blood gas analysis with arterial blood saturation levels and failed medical or surgical therapy. Four patients had sickle cell disease.

Patient-controlled interscalene analgesia after shoulder surgery: catheter insertion by the posterior approach.

Insertion and maintenance of an interscalene catheter is technically challenging using lateral or anterior approaches. We report a technique to provide continuous brachial plexus blockade through a 48-h infusion of ropivacaine 0.1% (5 mL/h with a 5 mL bolus dose, 20-min lockout interval) using a catheter inserted with cannula-over-needle technique on the posterior side of the neck in 120 patients undergoing shoulder surgery.

New landmarks for the anterior approach to the sciatic nerve block: imaging and clinical study.

Unlabelled: In this study, we assessed the reliability of the inguinal crease and femoral artery as anatomic landmarks for the anterior approach to the sciatic nerve and determined the optimal position of the leg during this approach. An imaging study was conducted before the clinical study. The sciatic nerve was located twice in 20 patients undergoing ankle or foot surgery, once with the leg in the neutral position and once with the leg in the externally rotated position.

CT-guided percutaneous treatment of inoperable pulmonary aspergillomas: a study of 40 cases.

Objective: To treat symptomatic pulmonary aspergilloma in patients who were not considered to be operable.

Material And Methods: Forty patients were treated by CT-guided percutaneous injection of amphotericin paste, the aim being to fill the cavity completely and create an anaerobic environment for the aspergillus. The aspergillomas had developed after bacillary infection and pulmonary fibrosis.

[CT-guided percutaneous treatment of inoperable pulmonary aspergilloma. Apropos of 42 cases].

The authors report 42 cases of symptomatic pulmonary aspergilloma treated by intracavitary percutaneous injections of Amphotericine paste. These patients were not considered as operable. The aspergillomas complicated tuberculosis sequels and pulmonary fibrosis.

High resolution chest CT in tuberculosis: evolutive patterns and signs of activity.

Purpose: The purpose of our study was to determine evolutive patterns and signs of active tuberculosis on high resolution CT (HRCT) scans.

Method: We followed up over 15 months 27 patients with postprimary pulmonary tuberculosis that was proven bacteriologically. CT scans were performed before, during, and after 6 months of anti-tuberculosis treatment.

[Extensive cerebral venous thrombosis resistant to heparin: local fibrinolysis with urokinase].

A 37 year-old man had headaches for 10 days, then a single tonic-clonic seizure and coma due to an extensive cerebral venous thrombosis. In spite of full-dose heparin treatment for 7 days, the clinical picture worsened along with increasing edema on CT-Scan. Direct thrombolytic treatment was then performed using transvenous catheterization and instillation of Urokinase (2.

[X-ray computed tomographic and radiographic aspects of thoracic actinomycosis].

Unlabelled: The aim of this study was to evaluate chest radiographs and computed tomography (CT) in patients with thoracic actinomycosis.

Material And Method: Chest radiographs and CT scans of 9 patients with proved thoracic actinomycosis were reviewed. CT scans were performed after intravenous contrast administration.

[X-ray computed tomographic tests in the diagnosis and treatment of amebic liver abscesses].

Purpose: The aim of this study was to evaluate the CT findings of amebic liver abscesses and its usefulness for treatment.

Methods: CT was performed in 51 patients with proved amebic liver abscess. CT studies were made before and after contrast injection.

[The double band sign: pleural tuberculosis in x-ray computed tomography].

We described on computed tomography, two cases of pleural tuberculosis with parietal pleural enhancement and thickening associated with another external high density line. We called this parietal pleural and extra pleural change, the "double band sign". After study of the regional anatomy, we think that this external line is the endothoracic fascia.

Percutaneous extraction of vertebral osteoid osteoma under computed tomography guidance.

The authors report two osteoid osteomas of the spine treated by percutaneous extraction under computed tomography (CT) guidance. CT helps to localize exactly and extract only the nidus with no further damage to the bone. This technique is very promising, with a limited approach and minimal bone resection allowing a short hospital stay and prompt functional recovery.

[Palliative percutaneous treatment under x-ray computed tomographic control of inoperable pulmonary aspergilloma. Apropos of 30 cases].

The authors report 30 cases of the percutaneous treatment of symptomatic pulmonary aspergilloma by injection of amphotericine paste in patients who were not considered to be operable. The treated aspergillomas had developed as a sequel to bacilliary infection and pulmonary fibrosis. Surgery was contraindicated in these patients on account of severe respiratory failure.

Inoperable pulmonary aspergilloma: percutaneous CT-guided injection with glycerin and amphotericin B paste in 15 cases.

Fifteen patients with active inoperable pulmonary aspergilloma underwent percutaneous injection of a special therapeutic paste of glycerin and amphotericin B. This paste was warmed just prior to injection, and filling of the lesional cavity was achieved in one session if it was possible to obtain anaerobic conditions for destruction of the aspergilloma. Injection was performed with computed tomographic guidance with use of an 18-gauge flexible needle and with administration of anti-coughing analgesia.

Osteoid osteoma: percutaneous resection with CT guidance.

In 24 patients with presumed osteoid osteoma in the appendicular skeleton (n = 23) and lumbar spine (n = 1), percutaneous resection with a drill system and computed tomographic (CT) guidance was performed. In the procedure, a 7-mm-diameter toothed drill inserted over a guide wire is used to remove the nidus. Twenty-three patients were successfully treated.

[Pulmonary dirofilariasis].

Dirofilariosis usually concerns dogs among which it is transmitted by mosquito bites. Human infection is rare and we describe here a case observed in a 75 years old woman in New Caledonia. A systematic pulmonary radiograph showed suspicious pulmonary nodules.

Percutaneous extraction of an osteoid osteoma of the lumbar spine under CT guidance.

We report one case of percutaneous extraction of an osteoid osteoma of the lumbar spine under CT guidance. We describe the procedure of nidus extraction. This technique allows precise removal of the nidus with pathologic verification after extraction.

[Magnetic resonance imaging of the knee. 3 cases of pigmented villonodular synovitis].

Pigmented villonodular synovitis is a benign monoarticular synovial proliferative disorder. Three cases involving the knee are reported. MR signs are highly suggestive: --joint effusion (blood); --hypointense synovial proliferation (irregular infrapatellar fat pad sign; hemosiderin deposits); --no loss of joint space.

[Magnetic resonance imaging in the bone sites of malignant non-Hodgkin's lymphoma. Apropos of 16 cases].

The primordial role of MRI in the staging of primary or secondary bone tumors has been clearly established. The authors report a study of 16 patients with NHL with suspected bone involvement, investigated by conventional radiography, bone scan, CT, bone marrow biopsy and MRI. The authors believe that, in the future, MRI will have an important role in the staging and follow-up of treatment of bone lymphomas.

[MRI evaluation in tracheal pathology. Comparison with tomography and x-ray computed tomography. Apropos of 30 cases].

The authors report a standardised comparison between MRI, CT and Tomography, in 30 cases of tracheal lesions (postintubation, tumors, external compressions and invasions). They conclude on the superiority of MRI because of its multiplanar visualisation, its soft-tissue contrast resolution and its capability to differentiate inflammatory granuloma.

[Aneurysm of the pulmonary artery. X-ray computed tomographic and MRI aspects. A case report and review of the literature].

A case of aneurysm of the pulmonary artery diagnosed by CT scan and MRI and confirmed by angiography is reported. The discussion considers the literature review.

[MRI in subacromial pathology. Report of 20 cases].

The authors report the results of MRI performed in 20 patients presenting clinical symptoms of subacromial pathology. The MRI results are correlated to the results of arthrography or arthro CT scan and also to surgical results. MRI is an excellent technique if a precise protocol with T2 weighted images is respected in order to visualize tears or minor perforations of the supraspinatus muscle.
