Ovarian tumors in children and adolescents: a series of 41 cases.

OBJECTIVE: Pictorial review with a detailed semiological analysis of ovarian tumors in children and adolescents to provide a relevant diagnostic approach. PATIENTS AND METHODS: Retrospective study (2001-2011) of 41 patients under the age of 15 who underwent surgery for an ovarian mass with a definite pathological diagnosis. RESULTS: Sixty-two percent of the lesions were benign, 33% were malignant and 5% were borderline. Germ cell tumors were most frequent (77.5%), followed by sex cord stromal tumors (12.5%) and epithelial tumors (7.5%). Malignant tumors were more frequent in children between 0 and 2 years old. On imaging, calcifications and fat were specific for germ cell tumors; the presence of a mural nodule was predictive of a mature teratoma (P<0.001). Predictive factors for malignancy were clinical, including abdominal distension (P<0.01) or a palpable mass (P=0.05), biological, including increased hCG and/or AFP levels (P<0.001) and radiological, including tumors larger than 12 cm (P<0.05), tumoral hypervascularity (P<0.01) and voluminous ascites (P<0.01). CONCLUSION: This semiological analysis confirms the role of imaging in diagnosing the etiology of ovarian lesions in children and adolescents and emphasizes the importance identifying tumoral hypervascularity, which, in addition to classic criteria, is highly predictive of malignancy.

[Cavernous hemangioma: rare incidentaloma of the adrenal gland]. / L'hémangiome caverneux : un incidentalome rare de la surrénale.

The hemangioma of the adrenal gland is an adrenal gland lesion rare, benign and usually asymptomatic. Discovered incidentally during an abdominal imaging study, it is part of incidentalomas. Imagery is the best to characterise these silent adrenal masses (computed tomography [CT], Magnetic Resonance Imaging [MRI]± Positron Emission Tomography [PET scan] with 18F-FDG). The main risks of the hemangioma are ignorance of malignancy, bleeding and abdominal mass syndrome. The analysis of the literature shows the importance of laparoscopy. A multidisciplinary discussion on this type of lesion appears indispensable both diagnostic and therapeutic.

[Periprocedural management of hemostasis risk in interventional radiology]. / Prise en charge du risque hémostatique au cours des actes de radiologie interventionnelle.

Given the increasing demand for interventional image-guided procedures, radiologists are increasingly sollicited by clinicians to participate in the management of patients prior to and after the interventional procedure, especially with regards to hemostasis. Therefore, radiologists should be familiar with the risk of procedure related hemorrhage. Based on consensus guidelines published by the Society of Interventional Radiology (SIR), the risk of hemorrhage for each interventional procedure will be classified. Recommendations for preprocedure testing based on the type of procedure planned will be reviewed. Finally, limitations of hemostasis parameters will be discussed along with management of anticoagulants and antiplatelet agents before the procedure.

[Hypertension and stress]. / Hypertension et stress.

Stress and adjustment to stress involve pathophysiological processes operating in the cardiovascular system, particularly concerning high blood pressure. Stress and high blood pressure are closely linked. Stress induces transient psychosomatic-related increases in blood pressure, but can also induce more permanent rise in blood pressure when associated with other environmental, psychological, or genetic risk factors. Symptomatic treatment of high blood pressure requires medicinal antihypertensive therapy; anti-stress therapy is an effective but not sufficient complement.
