Résumé: Les « petites » tumeurs neuroendocrines non-fonctionnelles du pancréas (TNEP-NF) sont des tumeurs rares mais d'incidence croissante. En effet, elles sont diagnostiquées de plus en plus fréquemment de manière fortuite sous la forme d'incidentalomes en lien avec les progrès et la diffusion de l'imagerie en coupe. Ces « petites » TNEP-NF sont souvent indolentes mais présentent un risque oncologique lié à la possible apparition de métastases ganglionnaires ou à distance. Leur prise en charge nécessite une expertise multidisciplinaire et des discussions collégiales lors de RCP dédiées, regroupant chirurgiens, oncologues, radiologues, médecins nucléaires, endoscopistes et anatomopathologistes, tous spécialisés. Pendant longtemps, le traitement de référence de ces tumeurs fut la résection chirurgicale, adaptée aux risques oncologiques et aux caractéristiques du patient et de la tumeur. Compte tenu de l'histoire naturelle de ces tumeurs de mieux en mieux connue et de la morbi-mortalité de la chirurgie pancréatique, les recommandations récentes proposent une stratégie de surveillance pour des patients très sélectionnés présentant des lésions considérées comme peu agressives ou indolentes. Cette stratégie est maintenant validée pour les TNEP non fonctionnelles < 2 cm, cN0, asymptomatiques et de grade 1. "Small" non-functional pancreatic neuroendocrine tumors (PNETs) are rare neoplasms but with an increasing incidence. They are mainly diagnosed as incidentalomas due to the widespread use of cross-sectional imaging. These "small" PNETs are often indolent but present an oncological risk of lymph node or distant metastases. Their management requires multidisciplinary expertise and collegial discussions bringing together surgeons, oncologists, radiologists, nuclear medicine physicians, endoscopist and pathologists, all specialized in neuroendocrine oncology. For a long time, the reference treatment for these tumors was surgical resection tailored to oncological risk, patient's and tumours characteristics. Given the increasingly well-known natural history of these tumors and the morbidity and mortality of pancreatic surgery, recent guidelines propose a " watch and wait " strategy for highly selected patients with lesions considered to be indolent. This strategy is now validated for non-functioning PNET < 2 cm, cN0, asymptomatic and Grade 1. [ABSTRACT FROM AUTHOR]

The authors describe the case of a 52-year-old woman, with a history of three different cancers. She has been presenting with a right pleural tumor found fortuitously while the patient was undergoing routine CT scanning. After surgical removal, the diagnosis of solitary fibrous tumor of the pleura was confirmed. The aim of this article is to review the clinical, radiological, and histological features of the disease as well as the treatment of this rare tumor. [ABSTRACT FROM AUTHOR]

Abstract: Thoracic aortic mural thrombus is a rare entity and potential source of serious systemic emboli. The progress of computed tomography (CT) angiography and the current use of transesophageal echocardiography (TEE) after any embolic event have considerably increased the frequency of diagnostic and there is a growing interest about the etiopathogenesis, which is still widely misunderstood. Therapeutic management remains controversial. We present a case of floating thrombus in the thoracic aorta detected by contrast-enhanced CT scan. This thrombus was responsible for two close major embolic events and was therefore managed surgically. Finally, outcome was favorable. [Copyright &y& Elsevier]
