[Extension to the thoraco-abdominal wall of actinomycoses. Value of computed tomography].

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.

[Tuberculous trochanteritis: value of ultrasonic diagnosis and x-ray computed tomography. Apropos of 3 cases].

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.

[Tumefactive biliary sludge. Ultrasonic aspects].

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.

[X-ray computed tomography and synovial chondrometaplasia].

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.

[Echographic and x-ray computed tomographic aspects of pneumatosis cystoides of the colon in the adult. Apropos of a case].

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.

[Generalized adenomyomatosis of the gallbladder: ultrasonographic appearance in one case (author's transl)].

Ultrasonographic images were correlated with radiological and pathological findings in a case of generalized adenomyomatosis of the gallbladder. Emphasis is placed on the importance of the methods employed for filling the biliary tracts with opaque medium, to confirm a suspected diagnosis suggested by the heterogeneous irregular thickening, with a fringed internal limit, of the gallbladder wall.

[Riedel's lobe. Echotomographic aspects].

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.

[Primary osteogenic renal sarcomas (author's transl)].

Renal sarcomas are rare malignant connective tissue tumors and they only represent 1 to 5% of renal cancers, according to various authors [18]. The appearance of a primary osteogenic tumor within a renal sarcoma is an extremely rare occurrence, and the mechanism by which it develops is not completely understood. The two interesting points raised by the case described in this report were the possibility of suspecting the diagnosis of renal osteogenic sarcoma on a straight x-ray film, and the images observed on ultrasonography.

[The value of arteriography in the diagnosis and treatment of post-traumatic secondary impotence (author's transl)].

Angiographic investigations in 9 patients with partial or total post-traumatic secondary impotence present for several years, confirmed the presence of traumatic vascular lesions involving, in nearly all cases, the artery of the penis or its branches (cavernous and bulbar arteries). Selective angiography of the pudendal arteries was able to guide treatment in 5 of these patients. Epigastrocavernous anastomoses, according to the microsurgical procedure developed by Michal, were performed with excellent results in 3 cases.

[An arterial catheter for multiple use in pediatrics (author's transl)].

The authors describe a pediatric catheter for use mainly in highly selective abdominal angiography (splenic, gastrica sinistra, and intestinal arteries). The catheter is made of polyurethane, is 65 cm long and is curved. It has a bore of 5 F and is introduced with a wo 32 guide, allowing a flow-rate of 10 ml/sec. The catheter point is polished by chemical means allowing penetration of the arterial wall without preliminary dilatation. This avoids vascular spasm and damage to the vascular wall at the site of puncture.

[Pseudo-sarcomatous osteomyilitis in the child (author's transl)].

The authors report three unusual cases of paediatric osteomyelitis resembling a lytic or mixed osteosarcoma. The severity of the radiological lesions is such that only a diagnostic approach is possible before surgical biopsy. Under the effects of treatment, osteolysis resolved in two cases by bone eburnation in two cases and pandiaphyseal sequestration in one case. These three cases were collected in less than a year. Thus osteomyelitis is currently adding new diagnostic traps in bone pathology in children.

[Periostitis or, rather, periosteal appositions in paediatrics (author's transl)].

In relation to a case of multiple fatigue fractures definitely diagnosed by scintigraphy and xerography, the authors report two other previous cases of spontaneous fractures at a single site in which the diagnosis was made only after surgical biopsy and histological examination. Recalling the frequent confusion arising in children between periosteal appositions and osteomyelitis or Ewing's sarcoma, and the different radiological phases of this type of fracture, they stress the necessity for a maximum effort to demonstrate the key element in the diagnosis: the cortical fissure. The latter is often minimal, at the limit of visibility and developing late. Thus repeated examinations and the use of special radiological techniques are necessary.

[Dacryography in the repair of the lacrymal pathways (author's transl)].

Dacryography is the only means of exploring the permeability of the lacrymal ducts and to conclude as the whether watering of the eyes is organic or functional. Pre-operatively, it is indispensable in order to orientate the surgical intervention, it is definitely indicated if there is a relapse of watering of the eyes. The appearance of new surgical techniques, such as the use of venous or arterial grafts, has given rise to a new interest in this technique, which up to now had been considered as an exceptional investigation.
