pleural versus pulmonary lesion.

look to mild lung infiltrate surrounding

lesion denote that the lesion is of pulmonary

origin and not pleural.

1-spherical in shape.

2-thick irregular wall.

3-acute angle with chest wall.

4-related to a bronchus.

E=lenticular shape with thin walls and smooth inner surface.

formin an obtuse angle with chest wall,pulmonary vessels are

compressed and displaced around empyema.

A=sherical in shape with thick iregular wall,and form acute

angle with chest wall,pulmonary vessels extend directly toward

abscess.

Reference:BiblioMed Textbook-Computed Body Tomography

lung abscess with acute angle with pleura.

it contains cavity with gas and fluid level.

arrow=fistula between esophagus and empyema

in the right side(rupture esophagus).

Reference:BiblioMed Textbook-Computed Body Tomography

Em=empyema with thickened and enhanced

pleura.

Ef=no pleural thickening and enhancement

denoting effusion and not empyema.

presence of gas inside empyema suggest

broncho-pleural fistula.
open arrow=edema and inflammation of the

extra pleural tissue.

cephalad veiw showed empyema more rounded

simulating lung abscess.

arrow head=thickened enhanced parietal pleura

arrow=thickening and inflammation of extra pleural

soft tissue in posterior hemithorax.

lung window setting showed bronchi and vessels

compressed and displaced by empyema.

a-extra-pleural lesion=displace both parietal and visceral pleura

resulting in obtuse angle between lesion and chest wall.

+ or - rib erosion.

b-pleural lesion=arise between two layers of pleura producing obtuse

angle with chest wall or become pedunculated and protruded into peripheral

lung parenchyma producing acute angle with chest wall.
