The left lung does not have a middle lobe, but does have a small portion that is called the lingula (latin for tongue). It just means pneumonia in that section. Can be tougher to see due to the cardiac shadow on chest xray. Poorly understood by all except the most cunning, lingular pneumonia can be difficult to diagnose.
I've heard it's tough to locate but once found, can be cured lickety split.
