☞ Catarrhal pneumonia, or Broncho-
pneumonia, is inflammation of the lung tissue, associated
with catarrh and with marked evidences of inflammation of bronchial
membranes, often chronic; -- also called lobular pneumonia,
from its affecting single lobules at a time. -- Croupous
pneumonia, or ordinary pneumonia, is an acute affection
characterized by sudden onset with a chill, high fever, rapid course,
and sudden decline; -- also called lobar pneumonia, from its
affecting a whole lobe of the lung at once. See under Croupous.
-- Fibroid pneumonia is an inflammation of the
interstitial connective tissue lying between the lobules of the lungs,
and is very slow in its course, producing shrinking and atrophy of the
lungs.
