I am showing today a case seen last week. Radiographs belong to a 35-year-old man with fever.
What do you see?
The answer will be published on Friday.

Findings: PA chest radiograph shows widening of the superior mediastinum (A, arrows). There is moderate prominence of both hila (A, red arrows) and two rounded opacities in the inferior aspect of the right hilum (A, yellow arrows). The lateral view shows convex bumps in the left hilum (B, red arrows).
Findings in both views are practically pathognomonic of mediastinal and hilar lymphadenopathies.
Changes in the PA radiograph are more evident when comparing with a previous film taken two years earlier.
In this case, lymphoma is the best possibility. For the sake of the patient I hoped it was infectious mononucleosis. Analysis discovered immature cells in the bloodstream. Further workup confirmed the diagnosis of acute lymphoblastic leukemia.
Final diagnosis: acute lymphoblastic leukemia with enlarged hilar and mediastinal lymph nodes.
Many of you discovered the enlarged lymph nodes, which makes me very proud.
Kudos for Amal Mahran, who was the first to give a detailed description.
Teaching point: I believe this case emphasizes the importance of comparing with previous studies. If I had shown the previous PA chest, I am sure the percentage of correct answers would had been close to one hundred percent.

Hello. I think the right heart border is ill defined in the PA view and there seems to be a wedge shaped opacity anteriorly in the lateral view, suggestive of middle lobe consolidation.
Partially defined opacity noted at the right lower lung zone not silhautting the right heart border and seen posterior to the heart in lateral view indicate right lower lobe location
Left hilar enlarged lymph node
Hilar lymphadenopthy on the left side?
Thickened rt paratracheal stripe, enlarged rt hilum… lymphadenopathy.
Enlarged bilateral hila with increased vascular markings.
Increased opacity in the retrosternal space- lateral view.
RIght paratracheal stripe appears widened
Both hila appear enlarged
Opacity noted inferior to right hila, adjacent to the right paraspinal border
Duoghnut sign on lateral CXR suggests adenopathy
Right para cardiac soft tissue density area seems to be separated from right hilar shadow which could be a mass lesion wi thin right middle lobe or vascular structure CT chest is advisable
Bilateral hilar enlargement (lymphadenopthy? Vascular?)
Thickening of the right paratracheal line.
Doubtful consolidation in the right lower lobe.
Good morning Professor
Opacity of upper and mid zone on right side
Right hilum increased opacity
—- provisional diagnosis: pneumonia, with consolidation in middle lobe and hilar adenopathy
Upper lobe collapse
Good morning Professor
Right prominent pulmonary artery .
Left hilum – a well-defined radioopacity noted
Further imaging required.
Neumonia lobulo medio
Donut´s sign in the lateral view…
Right hilar slightly elongated, well-demarcated opacity – bronchogenic cyst?
Thickened rt paratracheal stripe, enlarged bilateral hilum: lymphadenopaty, doughnut sign in lateral view. Right peribroncivascular tickening/mass.
