Circumscribed to endemic areas throughout tropical countries, filariasis is a rare and unknown disease in Europe. We report four cases of calcified filariasis involving the breast, supporting the diagnosis on the typical mammographic appearance of the calcified worms and the past history of filarial infection. Few reports have been published in the radiology literature about this infrequent manifestation of the parasitation. The purpose of this article is to show the mammographic characteristics of this disease that soon will be seen frequently in developed countries due to the increasing population from the endemic areas.
