Ghon Complex
Ranke Complex

General Considerations

• A “Ghon Lesion” or focus is a granuloma in the lung from a previous tuberculous infection
• It is a sequela of primary tuberculosis
• When there is a combination of a parenchymal granuloma and an involved hilar lymph node on the same side, the two together are called a “Ghon Complex”
• The combination of late fibrocalcific lesions of the lung and lymph node which evolved from the Ghon complex is referred to as the “Ranke complex”

Ranke Complex. There is a combination of a calcified peripheral granuloma (black arrow) and a calcified hilar lymph node (white arrow) on the same side. Several other, small calcified granulomas are seen in the right mid-lung field.
