hi
when i 1st saw this x ray, i thought of lobar pneumonia too but then it seemed not to fit coz how come the lower lobe is above the transverse fissure?! this is against anatomy, and it can't be the middle lobe either and if it was upper lobe, it would've been higher. so after some discussion with my friend
Sarah, she suggested why not "
pulmonary infarction" and that's what we agreed on and i think it fits perfectly, it's peripheral and wedge shaped and the obliterated costo phrenic angle goes with it.
