RESUMEN
We report a case of aspergillous bronchitis in an immunocompetent patient, recalling the clinical signs, laboratory findings and therapeutic management of this uncommon bronchopulmonary disorder related to aspergillus.

The new international lymph node classification adopted by the American Joint Committee on Cancer (AJCC) and the Union Internationale Contre le Cancer (UICC) is described and illustrated with computed tomography (CT). Anatomic landmarks for 14 hilar, intrapulmonary, and mediastinal lymph node stations are designated. Main differences between the new international classification and the American Thoracic Society (ATS) one are emphasized. In particular, mediastinal pleural reflection is now used to differentiate N2 from N1 nodes. The ATS 10L (left peribronchial nodes) and 10R (right tracheobronchial nodes) stations are now replaced by the AJCC-UICC station 10 (hilar nodes) and the AJCC-UICC station 4 (lower paratracheal, including azygos, nodes), respectively. This very important difference from the ATS classification helps classify the 4 lower paratracheal nodes as N2 nodes, even though the pleural reflection is not seen with CT. The 5 AJCC-UICC nodes are renamed subaortic nodes instead of aortopulmonary ATS nodes. Paraortic nodes, which previously were classified as 5 ATS nodes, are now included with the 6 AJCC-UICC nodes (now renamed paraaortic nodes instead of anterior mediastinal ATS nodes). This change helps accurate labeling because the border between 5 and 6 ATS nodes was not always clear on CT scans. Radiologists should be familiar with this new classification to be able to more accurately compare the lung cancer staging done in different institutions around the world.

We analyzed atelectasic processes occurring in the maxillary sinus. Several publications in the literature have tempted to analyze the pathogenesis. Clinically the processes are often silent and only revealed when the major opthalmological complication, enophthalmia, becomes patent. In other cases there is a long history of chronic sinusitis. There is a spectacular retraction of the maxillary sinus walls leading to collapse of the orbital floor and enophthalmia. We report four cases of maxillary sinusitis with atelectasia of the sinus walls at different stages of progression. These observations and data in the literature emphasize the importance, whatever the state of development, of endoscopic osteal decompression to avoid ophthalmological complications.

We report two cases of frontal and ethmoidal mucocele revealed by severe ophtalmologic complications and present the clinical data and computed tomography and magnetic resonance imaging results together with the treatment. The surgical approach and technique are discussed. Recovery of ophtalmologic deficiency was excellent.

Twenty patients with clinical acute pyelonephritis were investigated by routine CT scan. This examination was positive in 19 cases, demonstrating either a hypodense triangular image reflecting a disorder of blood supply or a mass syndrome. The CT scan can therefore confirm the diagnosis of acute pyelonephritis. It also defines the severity of the lesions and helps to guide treatment.

Lissencephaly, a developmental malformation characterized by absence of sulci, may be suggested in dysmorphic or epileptic infants. Real time ultrasonographic findings correlated with typical electroencephalographic abnormalities establish the diagnosis.

An infant born of a diabetic mother at 36 weeks developed three liver abscesses consecutive to umbilical vein catheterization. After medical treatment, 2 abscesses were aspirated percutaneously under ultrasonic guidance. The child recovered rapidly.
