Clinical Information
  • An acute form of tuberculosis in which minute tubercles are formed in a number of organs of the body due to dissemination of the bacilli through the blood stream.
  • I would say the hematogenous widespread dissemination of tuberculosis in the body. The term derives from the chest x-ray image of the tiny (1-5 mm) tuberculosis lesions which are seen through out the lung parenchyma.
