Obliterative pyelitis

A patient with severe undiagnosed and untreated pyelitis developed mural masses in the renal pelvis and in the infundibulum of the upper pole calyx. The masses were presumed to be inflammatory. The patient developed a severe stricture of the renal pelvis and complete occlusion of the upper pole calyx. This is an example of obliterative pyelitis, as described in the era before antibiotics were available.

Emphysematous pyelitis: findings in five patients

Emphysematous pyelitis (EP) is a benign entity. To our knowledge, it has not been reported frequently in the radiology literature. Previous articles have not focused on EP but rather have included other gas-forming entities (eg, emphysematous pyelonephritis [EPN]). The authors describe imaging findings in EP and distinguish them from findings in EPN in five cases. Computed tomography is the current method for demonstrating isolated gas production inside the urinary collecting system. The prognosis is excellent, with rapid complete recovery after medical treatment.     

Obliterative bronchiolitis following lung transplantation. Diagnostic utility of aerosol ventilation lung scanning and high resolution CT

A serious and often fatal complication of heart-lung transplantation is the development of obliterative bronchiolitis (OB). Currently the screening for OB is based on symptoms, pulmonary function tests, and transbronchial biopsies. The chest radiographs are often normal with OB. Obliterative bronchiolitis produces luminal narrowing of both bronchioles and bronchi resulting in areas of peripheral consolidation and occasional bronchiectasis. We report a patient in whom a chest film was normal, an aerosol ventilation lung scan was abnormal while a perfusion study was mildly abnormal. Simultaneously, routine CT was essentially normal while high resolution CT with 1 mm thick sections was clearly abnormal and demonstrated areas of consolidation. These imaging modalities detected clear-cut abnormalities at a time when the patient was symptomatic but prior to the development of demonstrable abnormality on chest radiograph.
