Introduction: Immunotherapy is now a standard of care in oncology. There is a need to improve our knowledge about immune-related adverse events, especially infectious diseases.
Case Report: We describe the case of a 49-year old male who received anti-PD1 therapy, to treat metastatic melanoma with pulmonary metastasis.
Coccidioidomycosis is a fungal infection endemic in the south west of the United States. Sixty percent of infected individuals remain asymptomatic. Symptomatic disease manifests itself with variable signs such as pneumonia, pleural effusion, empyema or acute respiratory distress syndrome.

Before the penicillin era, thoracic actinomycosis looked like tuberculosis or neoplasia with chest wall invasion and fistula formation.
Observation: We report the case of a 39 years old woman presenting with a chronic lung abscess of the left upper lobe hospitalised after several unsuccessful courses of antibiotics.
Ultrasound exploration of the thorax is a very useful imaging method in children. For adults, it is useful for pleural effusion, study of the diaphragm and to guide percutaneous puncture of targeted pleuro-parietal, mediastinal or peripheral parenchymal sites. Thoracic ultrasound remains underused, particularly as a bedside exploration technique or in emergency or intensive care situations.

The authors report a new case of that unfrequent syndrome of unexplained pathogeny.

The authors reviewed retrospectively 320 hepatic CT scans obtained in 300 patients during a 3-year period. These patients presented with benign (n = 64) or malignant (n = 236) hepatic tumors.

A 15-year-old girl with thoracic outlet syndrome associated with congenital pseudarthrosis of the clavicle was examined. The indication for treatment of congenital pseudarthrosis of the clavicle is discussed.

Material And Methods: Forty patients were treated by CT-guided percutaneous injection of amphotericin paste, the aim being to fill the cavity completely and create an anaerobic environment for the aspergillus. The aspergillomas had developed after bacillary infection and pulmonary fibrosis.
Mediastinal pseudotumors are present in less than 5% of patients with long-standing portal hypertension. These pseudotumors may be caused by para-esophageal collateral vessels or greatly dilated azygos or hemiazygos veins. Enhanced CT seems to be the best tool for the diagnosis and in evaluating the overall status of portosystemic collateral vessels.

The authors propose a radiologic diagnostic approach starting from the plain thoracic radiograph with study of the mediastinal lines and oesophageal transit and going on to the classifications made possible by modern CT and MR imaging. The proposed diagnostic procedure is based on nine mediastinal lines and two 'threads of Ariadne' which are the compartments where the masses are located and their behaviour at CT (densitometry before and after administration of an iodinated bolus) and at MRI (T1, T2, gadolinium-enhanced T1-weighted sequences).

Purpose: The purpose of our study was to determine evolutive patterns and signs of active tuberculosis on high resolution CT (HRCT) scans.
Method: We followed up over 15 months 27 patients with postprimary pulmonary tuberculosis that was proven bacteriologically. CT scans were performed before, during, and after 6 months of anti-tuberculosis treatment.
The aim of this retrospective study of 2,406 diagnostic percutaneous thoracic needle aspirations under computer tomographic control was to assess the diagnostic value of this method, the technical problems and the complications and finally, to refine the indications. Percutaneous needle aspiration had been carried out after negative fibreoptic bronchoscopy. The authors review their technique and show the value of biopsy material which is only slightly traumatised.

CT guided needle biopsy has an important place in the diagnostic approach to parenchymal as well as mediastinal tumours. But CT guidance allows also routine drainage of thoracic collections and sometimes thoracic sympatholysis.

Material And Method: Chest radiographs and CT scans of 9 patients with proved thoracic actinomycosis were reviewed. CT scans were performed after intravenous contrast administration.
We described on computed tomography, two cases of pleural tuberculosis with parietal pleural enhancement and thickening associated with another external high density line. We called this parietal pleural and extra pleural change, the "double band sign". After study of the regional anatomy, we think that this external line is the endothoracic fascia.

The treated aspergillomas had developed as a sequel to bacilliary infection and pulmonary fibrosis. Surgery was contraindicated in these patients on account of severe respiratory failure.

Embolisation was satisfactory in excluding the aneurysms and leading to a favourable outcome. The mechanism of the formation of these aneurysms which is extremely rare was discussed with reference to the few reports and literature.

Materials And Methods: Nineteen patients with histologically proved osteoid osteoma underwent CT and MR imaging before excision of the lesion. CT and MR images were compared regarding lesion conspicuity and detection of marrow, soft-tissue, and/or synovial changes adjacent to the primary lesion.
Fifteen patients with active inoperable pulmonary aspergilloma underwent percutaneous injection of a special therapeutic paste of glycerin and amphotericin B. This paste was warmed just prior to injection, and filling of the lesional cavity was achieved in one session if it was possible to obtain anaerobic conditions for destruction of the aspergilloma. Injection was performed with computed tomographic guidance with use of an 18-gauge flexible needle and with administration of anti-coughing analgesia.
