Nonresolving or slowly resolving pneumonia are defined by the persistence of pulmonary consolidation at chest radiography beyond the expected time of resolution i.e., 3 or 4 weeks, after probabilistic antibiotic therapy.
This is a common clinical problem that clinicians must be familiar with. Imaging plays a key role in the non invasive approach of the diagnosis along with clinical, bacteriological, biological, and epidemiological data. In some cases, imaging guides trans thoracic biopsy, a minimally invasive procedure, that allows for the diagnostic.
The goals of this poster are:
1- To describe the radiographic and CT features of some nonresolving pneumonia.
2- To elucidate the CT findings that may help making differential diagnosis among various entities.
3- To show the usefulness of trans thoracic biopsy in such patients.
This poster focuses on the most characteristic imaging patterns of some nonresolving pneumonia.
