  • COMMENTS:
    • In cal acute case of CBPP, usually only one lung is involved. If there are lesions in both lungs, the lesions are not symmetrical. The distribution is important for distinguishing CBPP from other pneumonias. The thoracic cavity on the affected side may contain a gallon or more of clear yellow or turbid yellow fluid mixed with strands of fibrin. The infected area of lung is usually adhered by fibrin and connective tissue to the thoracic wall. The amount of connective tissue is an indication of the age of the lesion. If the lung appears normal, the best way to find a small lesion is to do a thorough palpation.
