Furthermore, to review the utility of the aforementioned imaging modalities in different clinical contexts. Summary: The diagnosis of an inflamed appendix based on clinical evaluation, biological data and crosssectional imaging. US is the first line technique to consider and is the modality of choice for children, young and thin patients and women of childbearing age. An inconclusive ultrasound examination should lead to the realization of a CT. The appearance of the normal and pathological appendix needs to be clarified, in view of the modern technological developments of US as well as on the basis of the new CT methods (multidetector CT, with or without dual energy, low-dose acquisition). CT examinations can be performed with or without intravenous injection of contrast medium, accompanied by oral or rectal opacification, with variable diagnostic performance depending on the thickness of the sections and the possible use of reconstructions. MRI remains the second most important examination for young patients and pregnant women. In view of such technical progress, the plain films of the abdomen no longer have a role in everyday practice. Conclusion: A better knowledge of the US and cross-sectional appearance (CT-MRI) of the normal or inflamed appendix should allow the radiologist to contribute to an optimal management of this very frequent acute clinical situation. This approach reduces unnecessary radiation and negative appendectomies and optimizes the health care expenditures.

Significant stenosis of the celiac axis and thrombosis of the SMA were clearly depicted, along with the presence of collateral arterial supply. Endovascular treatment was successful in both cases. These cases confirm the possibility of detecting collateral flow at Doppler imaging in patients with mesenteric ischemia, both for diagnosis of mesenteric ischemia and endovascular treatment planning.

The mortality is high despite progress being made in the diagnosis and treatment of the disease. This review aimed to update knowledge on adult HLH pathophysiology, identify the numerous causes and help clinicians make early diagnosis and initiate treatment. Using Embase, we searched relevant articles published from 1 January 2010 to 31 October 2019, with the MESH term ‘haemophagocytic lymphohistiocytosis; macrophagic activation syndrome, adult’. The mean age at presentation is about 50 years, with a male predominance. The most frequent disease associations are haematological diseases, viral or bacterial infections and autoimmune diseases. The pathophysiologic mechanism is probably the combination of inherited genetic mutations and extrinsic triggers. The mortality rate is 26.5–74.8%. HScore is more efficient than HLH-2004 criteria to identify HLH, with diagnostic sensitiv...

Adequate knowledge of normal sonography findings is needed for optimal patient work-up. Although thyroid cartilage is rarely sonographically analyzed, there are anatomical variants detectable with sonography. These variants should not be confused with pathologies. Our case report is focused on cyst-like lesions of the thyroid cartilage, which are uncommon incidental findings when imaging is performed. The aim of this case report is to illustrate the ultrasound and magnetic resonance imaging appearances of these cyst-like formations. These formations are benign, have no clinical significance and do not require any additional assessment.

Des lésions de la paroi digestive et des anomalies du réseau vasculaire digestif sont à rechercher. En cas d'atteinte mésentérique, on observe un iléus grêle à parois fines, compliqué éventuellement d'une pneumatose et d'une aéroportie, un épaississement segmentaire ou extensif de la paroi grêle, homogène ou hétérogène. L'absence ou la diminution de la vascularisation des segments digestifs anormaux est à rechercher, en échographie-doppler couleur ou lors de la TDM réalisée avec injection de contraste intraveineuse. Les anomalies des troncs vasculaires sont l'occlusion localisée ou étendue du réseau splanchnique artériel ou veineux. En cas de colite ischémique, on peut visualiser les sténoses et les occlusions du réseau artériel splanchnique, avec leurs collatérales de vicariance.

Primary tumors were colorectal in 35 %, breast in 27 %, pancreatic in 17 % and others in 21 %. CEUS using SonoVue was employed with a low-mechanical-index technique and contrast-specific software using Siemens Elegra, Philips HDI 5000 and Acuson Sequoia; continuous scanning for at least five minutes. Results: CEUS with SonoVue increased significantly the number of focal liver lesions detected versus unenhanced sonography. In 31.4 % of the patients, more lesions were found after contrast enhancement. The total numbers of lesions detected were comparable with CEUS (55), triple-phase spiral CT (61) and MRI with a liverspecific contrast agent (53). Accuracy of detection of metastatic disease (i.e. at least one metastatic lesion) was significantly higher for CEUS (91.2 %) than for unenhanced sonography (81.4 %) and was similar to that of triple-phase spiral CT (89.2 %). In 53 patients whose CEUS examination was negative, a follow-up examination 3-6 mo later confirmed the absence of metastatic lesions in 50 patients (94.4 %). ConClusion: CEUS is proved to be reliable in the detection of liver metastases in patients with known extrahepatic primary tumors and suspected liver lesions.

La radiologie moderne est devenue incontournable dans ces types de situations. Dans ce chapitre, nous abordons quelques notions de radiologie conventionnelle et nous développons la contribution de l'imagerie en coupes dans la mise au point diagnostique des affections intestinales aiguës de l'adulte. Un diagnostic adapté est basé sur un usage rationnel de l'échographie et de la tomodensitométrie, permettant de réduire le nombre de laparotomies inutiles. Le diagnostic d'affections fréquentes ou inhabituelles est posé plus précocement, souvent avant la survenue de complications dramatiques comme la perforation.
