Unusual association of two unilateral anomalies present in adulthood: pulmonary hypoplasia and renal agenesis. Embryology and clinical expression.

We report a case of pulmonary hypoplasia associated with renal agenesia diagnosed in a 46-year-old woman admitted to hospital because of a viral pleuro-pericarditis. The chest x-ray raised the suspicion of left pulmonary hypoplasia. The CT scan and the Magnetic Resonance Image confirmed the presence of the congenital lung malformation and detected the absence of the left kidney. The clinical presentation, radiological diagnosis and embryological basis are described.

CT of congenital malformations of the lung.

We reviewed 40 cases of congenital malformations of the lung that were studied with both plain radiography and computed tomography (CT). We compared the CT findings with those of radiography. We found that CT was helpful in the management of these cases because it helped confirm the diagnosis, demonstrated unsuspected findings, and better depicted anatomic extent of anomalies, thus allowing better planning for surgery. We believe that CT is the method of choice for the study of congenital lung malformations and that it should be used before more invasive procedures such as bronchography or aortography.

[Aortic subvalvular annular aneurysm after closed thoracic traumatism. Presentation of a case].

A case of a 29 year old man with congenital aortic stenosis who developed a subvalvular annular aneurysm of the left ventricle after being run by a car is presented. At surgery his aortic valve was replaced and the opening of the aneurysm was closed with a patch of Dacron. Due to the dense adhesions to the aorta and left atrium no attempts were made to excise the sac, that was not compromising the dynamics of any one of these structures.

CT findings in Swyer-James syndrome.

Swyer-James syndrome (SJS) is usually diagnosed with plain chest radiographs obtained during inspiration/expiration. The authors studied patients with CT to assess its value in the evaluation of this syndrome. In patients with SJS, CT was useful in the determination of bronchial patency (all nine patients), lung parenchymal changes (subpleural infiltrates in six patients, atelectasis in two, and cavities in two), and the extent and degree of bronchiectasis (all nine patients). If CT is used for the evaluation of bronchiectasis, knowledge of the main findings associated with SJS (hyperlucent lung without anteroposterior gradient attenuation [n = 8], small lung [n = 6], and diminished central and peripheral pulmonary arteries [n = 9]) should facilitate the diagnosis of associated SJS. Expiration CT would support the diagnosis with demonstration of air trapping.

CT findings in metastatic ovarian tumors from gastrointestinal tract neoplasms (Krukenberg tumors).

The computed tomographic (CT) findings are reviewed in 7 patients with metastatic ovarian tumors from gastrointestinal tract neoplasms (Krukenberg tumors). All patients presented mixed ovarian masses. In 6 cases the masses were mainly cystic, with internal septa and focal or uniform enlargement of the cyst wall. In the seventh patient the ovarian mass appeared on the CT as mainly solid. The size of the neoplasm varied between 5 and 46 cm. Ascites was only seen in 1 case and in another the existence of a primary tumor in the sigmoid colon was demonstrated. In our cases the CT signs of ovarian metastasis were indistinguishable from primary tumors of the ovary.

Whole pelvic osteomyelitis: unusual finding in staphylococcal sepsis.

We describe an infrequent case of combined infection of bone, articulation and lung by Staphylococcus aureus, with affectation of all pelvic bones. Studies with 99m Tc pyrophosphate were repeatedly negative, becoming positive following the appearance of radiological signs.

Galactocele: three distinctive radiographic appearances.

Three radiographic appearances of galactocele of the breast not, to our knowledge, described previously in the literature were studied in 11 patients. Mammary nodules with distinct and separate hydro-fat levels were observed in five cases. A nodule containing mixed water and fat densities was seen in one patient, while in the five remaining patients, pneumocystograms revealed masses of a water density mixed with the injected air.

Epithienamycins-novel beta-lactams related to thienamycin. I. Production and antibacterial activity.

The epithienamycins are cell wall active antibiotics structurally related to N-acetylthienamycin. We have found forty-three isolated of Streptomyces flavogriseus which are capable of producing members of the epithienamycin family. Six major epithienamycin components, and xanthomycin, have been isolated from fermentation broth. Fermentation conditions can be varied to enrich for certain members of the epithienamycin family. All six components show activity in vitro versus a broad spectrum of bacterial species. The weight potencies vary 27 fold from the most active to least active.
