    Abstract Introduction: Transthoracic biopsies under fluoro-computer tomography (CT) guidance play an important role on the diagnosis and management of lung nodules, permitting histological examination and differentiation between benign and malignant lesions(1). Furthermore, with recent advances in target therapy, it is increasingly necessary to obtain tumor tissue for the analysis of molecular fingerprints allowing personalized treatment(1). Although many studies report low complication rates for this procedure, they are not negligible, urging the need for a structured and reproducible guide to reduce technique-related complications(1,2).

  2. Article: Acute aortic syndrome: Spectrum of imaging appearances.

    Abstract Objectives: The main objective of this paper is to illustrate and analyse the spectrum of MDCT findings of the entities that compose acute aortic syndrome (AAS) - namely acute aortic dissection (AD), intramural hematoma (IMH) and penetrating atherosclerotic ulcer (PAU) - discussing their pathophysiology. These related entities have a similar nonspecific clinical presentation mimicking other conditions such as myocardial infarction. Therefore, a high degree of clinical suspicion should prompt immediate confirmation by non-invasive imaging techniques which can modify its natural history, being MDCT the technique of choice, allowing accurate detection, characterization and complications evaluation in the Emergency Department.
    Methods: A detailed analysis of a series of clinical case of acute aortic syndrome seen at our Department is done, counselling with a review of the state of the art regarding the pathologic mechanisms, diagnostic evaluation and therapeutic management.
    Results: They share a common feature of separation of the aortic walls. In AD there is an inward intimal displacement or tear, creating a true and a false lumen (double lumen). Detailing the extent, configuration - including true and false lumina distinction - and complications, are essential to proper treatment planning. IMH is defined by the presence of acute haemorrhage within wall layers without no visible intimal flap or tear on conventional techniques. It can lead to wall infarction and consequent dissection. PAU is due to erosion of internal elastic lamina - reaching the media - by an atherosclerotic plaque in the setting of advanced atherosclerosis or, less commonly, after rupture of a mycotic plaque or due to connective tissue disorders, appearing as an irregular focal contrasted outpouching outside the lumen. It can precipitate IMH or a pseudoaneurysm and progress, frequently, to dissection or rupture, coursing with high mortality, if not treated. Well known complications are aortic rupture with massive haemorrhage, pericardial tamponade by hemopericardium, mediastinal hematoma or hemothorax, pulmonary artery stenosis and/or pulmonary haemorrhage or organ ischemia.
    Conclusion: MDCT findings knowledge allows a correct diagnosis. These life-threatening entities have an undistinguishable clinical presentation but different physiopathology mechanisms - reflected in differing radiologic findings - prognosis and management.

    Abstract Gastrointestinal stromal tumors account for the majority of the mesenchymal neoplasms of the gastric antrum, but other entities should also be considered. We present the case of a 70-year-old man with an ulcerated well-circumscribed polypoid submucosal mass in the gastric antrum which was proven to be a glomus tumor. CT showed progressive contrast enhancement. Magnetic resonance imaging showed a high T2 signal intensity and heterogeneous arterial contrast enhancement which became more homogeneous in later phases. We also present the case of a 50-year-old woman with a large polypoid mass occupying half the circumference of the distal gastric antrum that was proven to be a plexiform fibromyxoma. Contrast-enhanced CT and magnetic resonance imaging revealed a pattern of progressive and heterogeneous enhancement. Although gastrointestinal stromal tumors are the most frequent gastric mesenchymal neoplasms, other rare mesenchymal tumors such as glomus tumor and plexiform fibromyxoma may arise in the gastric antrum.

    Title translation Thymic lesions: A 4 years-review.
    Abstract Introduction: The difficulty in differentiating invasive from non-invasive thymic tumours solely by histological features, leads to the decision of resecting suspected lesions except in the presence of: (a) diffuse metastasis; or (b) typical imaging findings of thymic hyperplasia or after recovering from some recent stress. Therefore, the role of radiology is of the utmost importance in the initial evaluation and staging of thymic mediastinal masses.
    Methods: The objective of this study was to elaborate a retrospective analysis of the cases of thymic lesions that underwent surgery at the Cardiothoracic Department of Centro Hospitalar Vila Nova de Gaia/Espinho (CHVNG/E), from January 2013 to December 2016, illustrating their main radiologic findings with computed tomography (CT) images.
    Results: During the studied time period, 35 patients were diagnosed with thymic lesions including: 14 thymomas (40%), 9 thymic cysts (26%), 4 thymic hyperplasias (11%), 3 thymic carcinomas (9%), 2 thymolipomas (6%), 2 lymphomas (6%) and 1 neuroendocrine tumour (3%). The mean age of the sample was 60 years, ranging from 23 to 88 years, with a predomi- nance of the female sex (69%). In this article, 11 CT images and 1 thoracic x-ray are presented to illustrate the common imaging features of each thymic disease. Thymoma was the most frequent thymic lesion found in our 4-year case sample, similarly to what is described in literature for the adult age.
    Conclusion: Knowledge of the main radiologic findings of each pathological entity of the thymus is vital for the correct therapeutic management and disease staging, frequently allowing the differentiation of non-surgical from surgical lesions.
