Lymphangiographic findings in histoplasmosis

The lymphangiographic findings of histoplasmosis in an 11-year-old girl are presented and correlated with the histopathology of a mediastinal lymph node. Nonconfluent lymphadenographic defects with discrete margins measuring 2-4 mm in diameter were seen, corresponding to the microscopic demonstration of nodal granulomas of the same size. This is quite different from the lymphadenographic pattern usually present in lymphoma but might be seen in certain stages of other granulomatosis diseases.
