Imaging approach to deposition and neurogenic arthropathies

Deposition arthropathies are a heterogeneous group of diseases in which organic and inorganic substances accumulate in different regions of the body with significant complications and morbidity. Although they are clearly distinct entities, the clinical manifestations are similar, so that joint evaluation by imaging provides a more accurate diagnostic approach by identifying findings characteristic of certain pathologies and is considered the gold standard in certain conditions. However, neuropathic arthropathy, especially Charcot's foot, is an essential differential diagnosis in the joint evaluation of these patients because, although clinically similar, it manifests differently on radiological evaluation, with different treatment and prognosis. It is essential to know the main findings of the different imaging modalities, as well as their surgical performance, to propose the ideal study and differentiate these conditions with certainty.
