Avaliação por imagen do comprometimento osteoarticular e de nervos periféricos na hanseníase

Abstract

In leprosy, bone lesions due direct invasion of bacilli are low in incidence and these lesions exhibit radiologic findings of acute and chronic osteomyelitis sundar to those of other granulomatous infectious agents. The more common bone lesions are those due to injurious effects of trauma and infection imposed upon denervated tissues. Radiographycally air seen various degrees of reabsorption of the extremities involving hands and feet with the loss of digits and disorganizing arthropathies in small joints. The radiologic appearance are similar to other conditions in which there is sensory impairment like scleroderma, syringomielia and diabetes mellitus. The ultrasonography and magnetic resonance imaging (MRI) can be helpful in evaluation of the involvement of the peripheral nerves helping in the diagnosis of the neuritis, abscess and differential diagnosis in compressive syndromes.
