Abstract:

M. Tuberculosis is the responsible of a respiratory chronic disease that spreads through the respiratory tract and has the lungs as primary target. The increase of new cases, mainly due to migratory flows, has led to the reappearance of aspects of the disease that are now forgotten. The aim of this paper is focusing on a typical radiological sign indicative of progressive post-primary disease, actually no more considered in recent scientific literature, but well known to radiologists at the beginning of the 20th century: The infiltrate of Assmann-Redeker. The recognition of this sign makes it possible the recognition of cases of early post-primary disease and the immediate implementation of the correct therapeutic procedure. Our paper consists of a series of four cases admitted to the Policlinico Umberto I in Rome, in which these findings were not initially recognized. Retrospectively this radiological sign was found on the chest X-ray. All Patients underwent chest CT to compare this finding. Diagnostic confirmation was finally obtained through laboratory investigations and one case histology proven, after surgery.
