Emergency departments frequently encounter pathology resulting from injury to the foot and ankle, with approximately 6000 case per day in France. In an ankle sprain, 85% of the lesions involve the lateral collateral ligament. Many other, much rarer, types of lesion with different therapeutic consequences can present, however. Interpretation of the initial conventional radiographs is vital to establishing the type lesion and to proposing adapted and rapid treatment. The objective of this article is to review the various osteoarticular and ligament injuries encountered in the foot and the ankle.

We report two cases of Pulmonary Hemosiderosis. The first patient (adult male) had an angiosarcoma of the left auricle and developed pulmonary arterial hypertension, was treated by surgery and chemotherapy. The other patient (adult female) suffered from Idiopathic Pulmonary Hemosiderosis (IPH) and had been treated by corticosteroids for fifteen years, with one acute episode during this period. We discuss the etiological diagnosis and the contribution of chest radiographs, CT-scan and MR Imaging in this rare illness according to literature. IPH occurs mostly in childhood with acute and fatal issue, whereas presents as a chronic form in adults. Assessment of IPH requires large investigations to eliminate hemodynamic, hemato-, immuno-, carcinological disorders, and infectious agents as well. Review.
