Alimentary habits of free-living Psittaciformes vary significantly among different species. Amazona pretrei is under risk of extinction and has very specific free-living dietary habits, which are based on Paraná pine seeds. Hemosiderosis is a pathologic process characterized by intracellular accumulation of iron without other evident lesions. It is associated with increased prevalence of infect...

A case is presented in which a complex multicystic hemosiderin-containing lesion developed adjacent to a previously documented developmental venous anomaly (venous angioma). This lesion had the characteristic MR imaging appearance of a cavernous malformation. Follow-up MR imaging demonstrated a decrease in both the size and complexity of this lesion, which suggests at least a portion of the les...

Excessive iron storage sometimes causes diabetes in patients with hemochromatosis, a disease caused by iron overloading. We performed an immunohistochemical analysis to study an autopsy case of aplastic anemia and diabetic hemochromatosis caused by frequent blood transfusions, and extensive hemosiderin deposition was observed in the liver and pancreas. The pancreatic islets of the patient and a...
