[Radiographic and ultrasonographic diagnosis of a left thoracic mass]. / Diagnostic radiologique et échographique d'une masse thoracique gauche.

A chest roentgenogram of a 69-year-old man undergoing a check-up before prostate surgery showed a mass in the antero-inferior zone of the lung, just above the diaphragm. At ultrasonography, it was considered to be a thoracic ectopic kidney. This radiological case illustrates the place of this anomaly in the differential diagnosis of lung solitary mass, which can be explored with ultrasonography when retroperitoneal herniation is suspected.

[Radiography and ultrasonography in the management of bladder tumors: 71 cases at the National Hospital Center of Yalgado Ouedraogo (Burkina Faso)]. / Radiographie et échographie dans la prise en charge des tumeurs de la vessie: à propos de 71 cas au Centre hospitalier national Yalgado Ouedraogo (Burkina Faso).

The bladder's cancer is frequent in West Africa. Urinary schistosomiasis endemicity helps to explain this high incidence. It is a pathology of late diagnosis, little or badly explored by imaging. Through a retrospective survey of 71 patients' files aged in average of 51.7 years, all having a bladder's tumour which is clinically shown by an haematuria, the major symptom, often by a pelvic volume, and who have all gone through an abdominal echography and/or intravenous urography (IVU) and/or retrograde urethrocystography (UCR), we have tried to point out the role of imaging in the caring of this pathology in our working context. Imaging, with a 98.5% sensibility for sonography and 100% for IVU, took part in all the cases to the diagnosis, to the search of urinary signs of reflux, associated signs authorizing a diagnostic orientation, but was excluded from the evolutive follow-up due to the poverty of our populations. So, despite some limits specific to the survey, particularly the absence of historadiological comparison for all the files, echography and IVU with cystography have always led to malignancy diagnosis. Therefore they should be requested for any patient consulting for haematuria.

[Warm saline enema for reduction of intestinal invagination under the ultrasonographic guidance: preliminary results apropos of 2 cases]. / Désinvagination intestinale par lavement au sérum salé isotonique tiédi sous contrôle échographique: résultats préliminaires à propos de deux cas.

The authors describe the use of isotonic normal saline enema under US guidance in the treatment of acute uncomplicated intestinal intussusception in infants. The technique was successfully used in two patients aged respectively 18 and 16 months, with 11 and 9-month follow-up. The various steps of this technique and the results are analyzed and discussed. It is a valuable alternative to surgical treatment or hydrostatic reduction with opaque x-ray contrast under fluoroscopic guidance.

[Duodenal diaphragm in children (two cases)]. / Diaphragme duodénal chez l'enfant (à propos de deux observations).

Duodenal diaphragm is a rare cause of intestinal obstruction. Two pediatric cases are reported in which vomiting of bile-stained material and distension of the epigastrium were the main clinical signs. Roentgenograms and sonograms were highly suggestive. Duodenal bypass was easy to perform and effective. Nevertheless, it must be kept in mind that associated anomalies are frequent and may be severe.

[Contribution of medical imaging in osteoarticular manifestations of sickle cell anemia in the child]. / Apport de l'imagerie médicale dans les manifestations ostéo-articulaires de la drépanocytose chez l'enfant.

Drepanocytosis is one of the qualitative hemoglobinopathies which are the most widespread in the word. In a retrospective study on 16 drepanocytary patients observed at the Bordeaux Children's hospital, 7 patients showed medullar hyperplasia, 10 patients showed vaso-occlusive, and 4 patients showed infections. Medullar hyperplasia: bone demineralisation was the current appearance (47%), cortical thinning down (40.5%). They touch long bone. Thrombosis: bone demineralisation was the current appearance (86.3%) and touch long bone, 1 first appearance right femoral head infarct. Some particular appearances we found. 2 cases of "hand foot syndrome", 1 case ischemic aseptic arthritis and 1 case of vertebra "step staircase". Three salmonella pandiaphysite and 1 tuberculosis spondylodiscite were observed. The authors analyse the major radiological appearances of this hemoglobinopathy and recall the interest in knowing this disease even in low endemicity countries.

[Small-bowel duplication, apropos of a case in a child]. / Duplication du grèle (à propos d'un cas chez l'enfant).

A pediatric case of small bowel duplication is reported. Non-specific abdominal pain was the main complain. A fixed hypogastric mass was found. Abdominal palpation under general anesthesia disclosed a movable intraperitoneal mass which proved at laparotomy to be a cystic duplication of the small bowel. The cyst was excised according to Norris procedure. Recovery was uneventful. Complications and therapeutic aspects of this rare condition are discussed.

[Osteogenesis imperfecta diagnoses early, apropos of a case at the Yalgadou Ouédraogo National Hospital Center of Ouagadougou]. / Ostéogenèse imparfaite (O.I.) à révélation précoce (a propos d'un cas au Centre Hospitalier National Yalgadou Ouédraogo de Ouagadougou).

Osteogenesis imperfecta which represents a family tragedy for parents, a curiosity for physicians and radiologists, constitutes a real constitutional osteoporosis, usually rare with dominant autosomic transmission. Authors report a case of a 37 week amenorrhea living foetus, presenting an osteogenesis imperfecta. This affection, with early in utero manifestations, has a bad prognosis (baby deceased 72 hours after birth). Diagnosis was suspected at echography and conformed by x-rays investigations. The new born got also clinical and pathological examinations. Authors emphasize the unusualness and the gravity of these early clinical features. They insist on doing echography and radiography for the location of osseous and visceral lesions before and afterbirth.
