ABSTRACT
Angiomyxolipoma is a benign tumor considered as a variant of lipoma and that occurs mainly in the subcutis. The mediastinal location hasn't been previously reported. To describe the radiological features of this tumor in its posterior mediastinal location and to confront them to the pathological features. We report the case of a 49-year-old woman who was admitted for chest wall pain and neurologic disturbance of her two lower limbs. The chest X-ray showed a posterior mediastinal opacity. On CT examination, this mass contained some small areas of fat and enhanced intensily. Microscopic examination of the excised mass confirmed the diagnosis of posterior mediastinal angiomyxolipoma. Mediastinal location of angiomyxolipoma hasn't been previously reported. Clinicians and radiologists should be aware that this diagnosis should be suggested, among others, when there is a posterior mediastinal mass that contains fat and that intensely enhances with a possible spinal cord extension
ABSTRACT
Acute pulmonary embolism is a common disease with substantial morbidity and mortality in untreated patients. It requires an urgent positive diagnosis. To assess the prevalence of acute pulmonary embolism and calculate the sensitivity and specificity of multidetector CT for the diagnosis of acute pulmonary embolism in a hospital specialized in cardio-thoracic diseases. This is a prospective study conducted at Abderrahmen Mami Hospital, which included 200 consecutive patients suspected of acute pulmonary embolism and explored by a multidetector CT pulmonary angiography [16 slices]. Prevalence of acute pulmonary embolism was calculated at 37.5%. The multidetector CT has enabled an alternative diagnosis in 46 patients [40%]. The sensitivity and specificity of multidetector CT were calculated respectively 89.6% and 100%. The prevalence of acute pulmonary embolism, in a hospital specialized in cardio-thoracic diseases, is higher than that found in general hospitals. High sensitivity and specificity of multidetector CT makes it the gold standard for the diagnosis of pulmonary embolism
