ABSTRACT
Hyperostosis frontalis interna was first described in 1719 in association with obesity and hirsutism, forming Morgagni's syndrome. A high prevalence and a lack of studies demonstrating a strong correlation between these different signs currently question the existence of such a syndrome. Hyperostosis frontalis interna predominates in women. The anomaly exclusively involves the inner table and constantly spares the diploe and the external table. The main differential diagnosis of cranial hyperostosis is made between meningioma, osteoma, Paget's disease and fibrous dysplasia. The clinical implication of hyperostosis as well as its etiology are also debated.
L'hyperostose frontale interne a initialement été décrite en 1719, en association avec une obésité et de l'hirsutisme, formant ainsi le syndrome de Morgagni. Une prévalence élevée et un manque d'études confirmant une corrélation entre ces différents signes remettent actuellement en doute l'existence de ce syndrome. L'hyperostose frontale interne prédomine largement chez la femme. L'affection concerne exclusivement la table interne et épargne constamment le diploé et la table externe. Le diagnostic différentiel principal des hyperostoses crâniennes s'établit entre le méningiome, l'ostéome, la maladie de Paget et la dysplasie fibreuse. L'implication clinique de l'hyperostose ainsi que son étiologie sont également débattues.

Contrast-enhanced cardiac magnetic resonance imaging allows the evaluation of both myocardial perfusion and myocardial tissue characteristics. This paper reviews different microvascular and non-vascular conditions that can cause abnormal findings on contrast-enhanced myocardial magnetic resonance imaging. Knowledge of their characteristics can avoid misinterpretation and avoid inappropriate referral for further invasive imaging in patients suspected of myocardial vascular disease.

The aim of the study was to evaluate the incidence of asymptomatic coronary heart disease in patients with cardiovascular risk factors and evaluate the diagnostic value of myocardial stress perfusion magnetic resonance as screening test in these patients. We performed a retrospective analysis of 103 consecutive asymptomatic patients with at least one clinical risk factor for cardiovascular disease, who have undergone myocardial stress perfusion magnetic resonance. For respective evaluation of ischemic myocardium and infracted myocardium, magnetic resonance imaging protocol included the study of both myocardial viability by late enhancement imaging and first-pass perfusion at rest and during maximal stress (adenosine). The reference standard was catheter coronary angiography for 10 patients and clinical follow-up for 93 patients. The incidence of coronary heart disease was 22/103 (21%), including 6/103 (6%) ischemia and 16/103 (15%) infarcts. Respective sensitivity, specificity, negative and positive predictive values for myocardial stress perfusion magnetic resonance in detecting ischemic myocardium were 100, 97, 67 and 100%. Myocardial stress perfusion magnetic resonance can be regarded and further investigated as screening test for the detection of asymptomatic coronary heart disease in high-risk subjects. Prospective studies, larger study groups and cost-effectiveness analysis are needed.

Only few dissecting aneurysms type A survive without surgery. Opposingly, the dissecting aneurysms type B are successfully managed by the medical treatment "anti-impulsion". A personal series is reported, that evidence important cardiovascular mortality in the follow-up in chronic dissecting aneurysms type B; one part of this late mortality is linked to rupture of the thoracic descending aorta. Thus, the prevention of this late mortality depends on a strict follow-up of the characters and dimensions of descending aortic thoracic aorta.
