Consolidation

The lung is said to be consolidated when the alveoli and small airways are filled with dense material.

This dense material may consist of:
•  Pus (pneumonia)
•  Fluid (pulmonary oedema)
•  Blood (pulmonary haemorrhage)
•  Cells (cancer)

Lobar consolidation:
– Alveolar space filled with inflammatory exudate
– Interstitium and architecture remain intact
– The airway is patent
– Radiologically:
•  A density corresponding to a segment or lobe
•  Air bronchogram, and
•  No significant loss of lung volume

Venous eczema  occurs as a result of venous hypertension causing fluid to collect in the tissues. The stasis of this fluid in the soft tissues results in activation of the innate immune response and subsequent inflammation. Venous eczema has the following clinical characteristics: ·          Itchy red, blistered and crusted  plaques ; or dry fissured and  scaly   plaques  on one or both lower legs (commonly mistaken for cellulitis) ·          Atrophie Blanche (white irregular scars surrounded by red spots) ·          Orange-brown patches pigmentation due to haemosiderin deposition ·          Lipodermatosclerosis If you’re not sure if the patient has venous eczema, ask “Is it itchy?” Varicose eczema is often intensely pruritic and this is a common indication for intervention.
