I would like to start a new section entitled “The wisdom of Dr. Pepe”. I like aphorisms and in this section I would present an aphorism that will summarise the teaching point of the cases presented.
Today I want to show two different cases. Radiographs of Case 1 belong to 86-year-old woman with chest pain. Pulmonary abnormalities are unchanged in comparison with a radiograph taken one year earlier.
Check the images below, leave your thoughts in the comments section. We will publish new images on Wednesday and the answer on Friday!
Click here for the see the images for CASE 1
1. TB granulomas
2. Bronchioalveolar carcinoma
3. Amyloid nodules
4. None of the above

Final diagnosis: achalasia (surgically proved) with pulmonary aspiration, possibly atypical TB granulomas (unproven).
Radiographs of Case 2 belong to a 23-year-old woman with cough and low-grade fever.

Showing CT images of the chest. Do they help you?

2. Chronic aspiration
4. None of the above

Final diagnosis: tuberculosis of RLL with widespread mediastinal adenopathy.
Congratulations to Olena and MK for their participation and correct diagnosis.
I am showing these cases to emphasize the importance of examining carefully the radiographic images. Aside from having the same etiology (TB), both cases have multiple findings and the sum of all of them are the clue to the right diagnosis.
In satisfaction of search, findings are missed because we don’t search for additional abnormalities after the first one is found. When there are multiple findings, additional ones are discovered less than 50% of the time.
So, once again, try to avoid satisfaction of search. Remember that it accounts for approximately 22% of our errors.
Follow Dr. Pepe’s advice:
Don’t let one abnormal finding keep you from looking for another.

Case 1. Hydroaereus level in upper esophagus. In the lateral view the trachea is displaced towards the front. Pulmonary bilateral and diffuse nodules. I think it could be an Amiloidosis with pulmonary and esophagical disease.
Case 2. Pulmonary consolidation with bronchogram in the RLL with a thickened right paratracheal line (possibly adenopathies). I think if it is a pneumonia the patient would have high grade fever and she has low grade fever, so I think in lymphoma.
1. In the first case there is widening of the esophagus is seen – achalasia can not be excluded. Changes in the lung parenchima can be interpreted as “old” – fibrosis and TB granulomas or occupational disease.
2. In this case cavitating bacterial pneumonia is suggested, but tuberculosis can not be excluded. For differential diagnosis after the nonspecific treatment follow-up images are needed.
Due to new images of case 2 – tuberculosis is more likely
Case 1 achalasia?
Rt paratracheal and left hilar opacities – ?lymph nodes
Rt lower lobe consolidn
+ round opacity ?effusion
Case 2. Necrotic mediastinal adenophaties in CT with RLL consolidation in x-ray and CT so TBC will be better option than lymphoma.
I can´t see the new images of case 1….
There are no new images of case 1; only of case 2.
There are only new images for case 2. We have not publish new images for case 1. You will have to come back on Friday to see more images (and the answer!) 🙂
