Nipple shadows can often mimic pulmonary nodules. Clues to nipples being the source of the apparent nodules on the lateral radiograph, bilaterally and “lesions” whose inferior and lateral borders appear sharper than their superior and medial margins....
Components of the PA mediastianl shadow (A) include SVC (1), ascending aorta (2), RA (3), IVC (4), aortic arch (5), pulmonary trunk (6), LA appendage (7), and LV (8). Mediastinal compartments on the lateral film (B) include: superior (S), anterior (A), middle (M) and...
This is a normal lateral film of a female patient. Note the spine (sp), anterior costophrenic angle (acpa), gastric air bubble (gab), trachea (tr), left mainstem bronchus (lbr), right mainstem bronchus (rbr), aortic arch (ao), anterior/retrosternal (acs) and...
On a film taken in full inspiration, the right hemidiaphragm should project over the 6th anterior interspace or 10th rib posteriorly. Films taken without a full inspiration are described as having a “poor inspiratory result”. This may result from a poor inspiratory...
Hypertrophic First Rib Rib hypertrophy, often at the costochondral junction and particularly involving the first rib, commonly mimics a lung nodule on the PA projection. It has been called “the medical student’s tumor.” Clues that the “nodule” is in fact due to rib...
