Among 500 C.T. scan of temporomandibular joint (T.M.J.), examined since 1982 by bilateral direct sagittal method (Department of Radiology, Pr. A. TREHEUX, C.H.U. Nancy-Brabois), the authors have retained 14 cases of patients with symptoms related to dysfunction of the T.M.J. cured by surgery (Department of Maxillo Facial Surgery, Pr. STRICKER, C.H.U. Nancy). These cases were chosen among hundred patients annually examined by C.T. scan, for various diseases (dysfunctions of the T.M.J., traumatisms, infections, inflammatory diseases...). These correlations between radiology and surgery about 26 T.M.J. (2 patients underwent surgery only on one side) were: an accuracy with surgical findings for 19 cases (76%); in 6 cases (23%), a meniscus anteriorly displaced, non detected by C.T. scan was found by surgery; 2 cases of meniscus perforations (one in the frontal plane, the other sagittal) were surgical findings; in 1 case, a displacement was under-valued by C.T. scan; in 3 cases, arthrosic changes (1 case of REITER syndroma) were characterized by C.T. scan. The authors emphasize the value and the limits of evaluation of the internal derangements of the T.M.J. with direct sagittal C.T.

Important advances in the use of CT scan imaging for exploration of the temporomandibular joint include the obtaining of direct sagittal section images and the possibility of surveillance. This avoids the need for more invasive and painful techniques such as arthrography. The position of the meniscus can be determined from either direct or indirect signs and bone structures and muscles are particularly clearly demonstrated. This technique can be used while awaiting more widespread availability of NMR apparatuses for meniscal exploration.

Four patients with deep visceral actinomycosis infections presented evidence of extension to the thoracic or abdominal wall. Investigation of the chronic parietal suppuration by CT scan imaging allowed definition of the nature and extent of parietal infiltration, and notably to demonstrate its anatomical continuity with the often unrecognized deep focus: chronic lung disease, appendicular or colon mass, chronic genital infection in patients with intra-uterine device.

Always frequent and often misleading, chronic sinusitis are multifactorial. Consequently, the role of teeth apical infection is largely underestimated. The difficulties of interpretation of the sinus radiographic imaging are well established, particularly in the study of the dental with sinus border. The clinical circumstances in which the responsibility of teeth can be involved, are studied. Diagnosis insufficiency are frequent, and inadequate procedures can be undertaken. The particular conditions to obtain good polycyclicidal tomographs pictures are described and demonstrated. In special cases, with the eventual contribution of the bacterial-sensitivity evaluation, these sinusal-dental tomographs allow a relevant diagnosis.

Scanography allows diagnosis of radiotransparent intra-articular foreign bodies and establishment of their synovial origin, sometimes even in the absence of joint opacification. It provides an overall assessment of the joint that can be improved by arthrography. Clinical and standard radiologic pictures of primary synovial chondrometaplasia (synovial osteochondromatosis) and intra-articular foreign bodies can cause confusion if the latter are modified by secondary chondrometaplasia. Scanographic analysis of islets of chondrometaplasia suggests their primary nature in the presence of plaques of calcification of a small size, of low density and diffused throughout the image while peripheral, lamellar, dense calcifications are suggestive of secondary lesions.

Trochanteritis is a rare osteoarticular site of tuberculosis which initiates within the serous bursa of the gluteus maximus and extends only secondarily to the greater trochanter. Its course is a slow one. Diagnosis is usually delayed but should be made earlier by the use of ultrasound and the CT scan. These provide details of the bone remodelling detected on standard radiography, and show the presence of a variable fluid collection of a topography that attaches it to the serous bursa of gluteus maximus, and provides a guide to diagnostic needle puncture for biopsy. Overall data allow improved adaptation of medico-surgical treatment.

Twenty two patients presenting a typical sonographic pattern of tumefactive biliary sludge are studied. In all cases was observed a polypoid mobile, rounded mass, without acoustic shadow. The lesion stayed in the gallbladder in 15 cases and in distended main bile duct in 3 others. There was a double localisation in 4 cases. Seven verified cases proved to be constituted of very thick biliary sludge.

Based on findings in 28 cases of hepatic alveolar echinococcosis, the most frequently encountered signs constituting a true "scannographic profile" are described. These include global hypodensity with poor or absent intensification of image after iodized contrast, very high frequency of intralesional calcifications often combined with necrotic plaques, peripheral retraction. Employed after standard radiologic imaging and ultrasonography, the scanner should be used to provide positive confirmation of the diagnosis of the parasitosis, and as a reference element in evaluation of intra- and peri-hepatic extension, both during the moment of choice of initial therapy and during follow-up reviews.

The authors describe the radiologic appearance of annulo-aortic ectasia in 26 patients who had plain chest radiography and aorto-seriography. Two also underwent C.T. Aortography is the most performing method to appreciate the extent of aortic ectasia, the perturbations of the aortic root and to diagnose acute or chronic dissections. Aortography remains a most valuable complement of echocardiography for preoperative staging.

A case of pneumatosis cystoides Coli located in the sigmoid in an adult is reported, with emphasis on US and CT aspects. CT patterns of pneumatosis cystoides Coli are highly significative; particularly attenuation values measured in the endoluminal polypoid images are characteristics and represent an interesting contribution to the diagnosis of this disease.

By means of a review of a series of 30 cases of hepatic alveolar echinococcosis, the authors propose a classification of the various sonographic patterns; they point out the heterogeneous form which associate necrosis and calcification inside an hyperechoic mass and is the most frequent. The interest of ultrasonography for detection of lesions, its limits for diagnosis of extension, the contribution of percutaneous biopsy are discussed, as its place in the survey of the affection.

The place of standard CT scan imaging more particularly when combined with double contrast arthrography, is defined in the preoperative screening of patients with anterior instability of the shoulder. The joint scan provides complete data on the anatomic elements of the shoulder lesion, particularly with reference to the glenoidal labrum and the anterior capsular structure. It is also of major diagnostic value in painful subluxations.

The authors recall the main pathologic and physiopathologic data necessary to understand the angiographic patterns of hepatic alveolar echinococcosis, by means of a rereading of a personal series of 37 cases. They show that this affection has a diagnostic angiographic shape which associate four signs: avascular aspect of the lesions, regular invasion of vessels, presence of a collateral circulation, absence of neovascularisation. Digestive angiography stays a good diagnostic method for the parasitosis, when epidemiological context, ultrasound or CT scan gave no explicit conclusion. It keeps an interest in the preoperative evaluation and in the supervision of portal vein.

The acquired or congenital nature of Riedel's lobe, a rare anomaly of hepatic lobulation, is a subject open to controversy. Normally asymptomatic, it presents as a palpable mass in the right hypochondrium leading to possible confusion with an hepatic or a renal tumor. Correct diagnosis can be established by the characteristic findings an ultrasonography. The typical anatomical and clinical features of this hepatic morphological variant are discussed in relation to ultrasound recordings obtained from three patients with a Riedel's lobe.

Stress fractures of the pelvic ring should be suspected everytime a patient complains of hip pain. These stress fractures are more likely to occur in elderly, obesity, rheumatoid arthritis, osteoarthritis of the hip and after total hip replacement. A bone scan should be performed for early diagnosis, for roentgenolographic evidence of stress fracture often one ago two or three weeks behind the onset of symptoms.
