BACKGROUND: Protocols including combination of surgery and radiotherapy are more and more frequent in the treatment of bone tumors of the spine. In metastatic disease, combination of surgery and radiotherapy is since long time accepted, as based on clinical evidence. In primary tumors, combination of surgery and radiotherapy can be considered in all the cases in which a satisfactory oncological margin cannot be achieved: high-grade malignancies, recurrent tumors, huge tumors expanding in an extracompartimental area, and when tumor-free margin requires unacceptable functional sacrifices...

The number of patients with immunosuppression is rising worldwide. The spectrum of diseases and pathogens in these patients differs widely from that of immunocompetent patients due to frequent opportunistic infections. Symptoms are sometimes unspecific, and imaging plays a key role in the management of these patients. The lungs are a frequent site of infection in immunosuppressed patients. Chest X‑ray is the starting point for radiological diagnostics, but shows only limited sensitivity and specificity for infections with atypical pathogens...

BACKGROUND: Thoracic injuries are a leading cause of death in polytrauma patients. Early diagnosis and treatment are of paramount importance. Whole-body computed tomography (WBCT) has largely replaced traditional imaging techniques such as conventional radiographs and focused computed tomography (CT) as diagnostic tools in severely injured patients. It is still unclear whether WBCT has led to higher rates of diagnosis of thoracic injuries and thus to a change in outcomes. METHODS: In a retrospective study based on the trauma registry of the German Trauma Society (TraumaRegister DGU(®)), we analysed data from 16,545 patients who underwent treatment in 59 hospitals between 2002 and 2012 (ISS ≥ 9)...

This study aimed to estimate the organ dose reduction potential for organ-dose-based tube current modulated (ODM) thoracic computed tomography (CT) with a wide dose reduction arc. Twenty-one computational anthropomorphic phantoms (XCAT) were used to create a virtual patient population with clinical anatomic variations. The phantoms were created based on patient images with normal anatomy (age range: 27 to 66 years, weight range: 52.0 to 105.8 kg). For each phantom, two breast tissue compositions were simulated: [Formula: see text] and [Formula: see text] (glandular-to-adipose ratio)...

BACKGROUND AND PURPOSE: Quantitative tissue characteristics derived from medical images, also called radiomics, contain valuable prognostic information in several tumour-sites. The large number of features available increases the risk of overfitting. Typically test-retest CT-scans are used to reduce dimensionality and select robust features. However, these scans are not always available. We propose to use different phases of respiratory-correlated 4D CT-scans (4DCT) as alternative. MATERIALS AND METHODS: In test-retest CT-scans of 26 non-small cell lung cancer (NSCLC) patients and 4DCT-scans (8 breathing phases) of 20 NSCLC and 20 oesophageal cancer patients, 1045 radiomics features of the primary tumours were calculated...

PURPOSE: Chance fracture of the high thoracic spine is rare, and its impact on the adjacent cervical spine can be important. METHODS: We present the case of a 16-year-old male, who fell down from a 2 m height, in an unknown context as he has a mental retardation, and no witness saw the accident. Initial CT scan revealed a comminuted depressed fracture of the right parietal bone, associated with a chance fracture at the level of T3 with a kyphosis and bilateral lung contusion...

Herein, we report the case of a 60-year-old man, a smoker with a history of arterial hypertension and diabetes mellitus. After computed tomography (CT) for an episode of hemoptysis, the patient underwent elective thoracic endovascular aortic repair (TEVAR) because of a degenerative aneurysm of the descending thoracic aorta. The area of perianeurysmal pulmonary atelectasis reported on the CT scan was not considered. Three months later, he developed an aortopulmonary fistula without endoleaks. Although TEVAR is a relatively safe procedure, no detail should be overlooked in the preoperative evaluation in order to avoid life-threatening complications...

Amiodarone-induced pulmonary toxicity (APT) is a severe side effect that can lead to lung fibrosis or fatal respiratory failure. Usually APT occurs during long term therapy after administration of prolonged loading doses or high cumulative doses. We present the case of a 58 year old woman who underwent thoracic surgery with lobe resection. She developed atrial fibrillation with hemodynamic-instability on the first post-operative day. We initiated amiodarone therapy and four days later she developed respiratory failure...

BACKGROUND: Pulmonary thromboembolism (PE) is a major disease in respiratory emergencies. Thoracic CT angiography (CTA) is an important method of visualizing PE. Because of the high radiation and contrast exposure, the method should be performed selectively in patients in whom PE is suspected. OBJECTIVES: The aim of the study was to identify the role of clinical scoring systems utilizing CTA results to diagnose PE. MATERIAL AND METHODS: The study investigated 196 patients referred to the hospital emergency service in whom PE was suspected and CTA performed...

Cavitary lung lesions of various etiologies may be encountered in patients with respiratory symptoms associated with fever. Non-malignant cavitary lesions may mimic malignant lung lesions on most of radiographic modalities including chest radiographs or thoracic computed tomography (CT). Primary lung malignancy can be detected in as high as one-fifths of CT thorax as cavitary lesions and the remaining aetiologies may be due to bacterial, parasitic, and invasive fungal infections, as well as Granulomatosis with polyangiitis (GPA), sarcoidosis, septic thrombo-embolism, and lung metastasis from extra-pulmonary primaries...

Medical imaging modalities such as computed tomography (CT) combined with computer-aided diagnostic processing have already become important part of clinical routine specially for pleural diseases. The segmentation of the thoracic cavity represents an extremely important task in medical imaging for different reasons. Multiple features can be extracted by analyzing the thoracic cavity space and these features are signs of pleural diseases including the malignant pleural mesothelioma (MPM) which is the main focus of our research...

The extrapleural space (EPS) is an anatomic space at the periphery of the chest that can be involved in a number of disease processes. This space lies between the inner surface of the ribs and the parietal pleura and contains adipose tissue, loose connective tissue, lymph nodes, vessels, endothoracic fascia, and the innermost intercostal muscle. It is often overlooked on cross-sectional imaging studies and almost invariably overlooked on conventional radiographic studies. At conventional radiography, the EPS occasionally can be seen when there is extrapleural fat proliferation, which might be confused with pleural thickening or pleural effusion...

The tertiary stage of syphilis is nowadays extremely rare, showing predilection for the cardiovascular and nervous systems. A 57-year-old Caucasian man sought medical assistance due to back pain that evolved to paraplegia of the lower limbs. A thoracic CT scan demonstrated an important aneurysmatic lesion of the descending thoracic aorta causing erosion of the vertebral bodies and VDRL and FTA-abs positivity. Although rare, syphilitic aortitis, the hallmark of cardiovascular syphilis, should be considered in the differential diagnosis in patients with thoracic aneurysm when in the absence of classic risk factors for atherosclerosis, especially in cases that progress with erosion of vertebral bodies...
