title: Radiological study of two disseminated malignant non-Hodgkin lymphomas affecting only the bones in children.
abstract: Malignant non-Hodgkin lymphomas are a neoplastic proliferation of lymphoid cells whose clinical manifestations are extremely variable. All tissues can be affected. There may be localization in lymphoid organs (Waldeyer's ring, spleen, digestive tract), other localizations (lungs, pleura, liver, bone marrow, central nervous system), and unusual localizations. Although bone marrow is often affected, bone involvement is very rare in the early stages of the disease. This report concerns the radiological study of two disseminated malignant non-Hodgkin lymphomas affecting only the bone in children.
