The best submissions for the “Normal variant or disease” interlude at ECR 2018

Dear Friends,

Over the last couple of years, one of the last sessions at the ECR has always covered 20 interesting cases from various subspecialties, which the audience is asked to solve in an interactive way to broaden and update their knowledge.

In between, the very best submissions from the global radiological community have been presented in an interlude lecture. The best submission has always been awarded with a prize and a certificate.

Due to time limits, not all submitted cases can actually be shown onsite, but the session’s rising popularity has resulted in increasing numbers of submissions of excellent quality and didactic value. This is why we would like to give our submitters the opportunity to reach a broader audience by posting the best cases here on the ESR Blog.

This year’s topic was Normal variant or disease to avoid misdiagnosis, overdiagnosis, unnecessary and costly work-up, as well as patient’s concerns.

When we think back of our time in medical school and remember our studies of embryology, we have probably all thought at some stage, how astonishing it is that a viable fetus develops and a healthy newborn is delivered. Embryological development is so complex that an awful lot can go wrong at any stage. Fortunately, real malformations are rare. In our professional life as radiologists, though, we are not infrequently dealing with normal variants, when development is arrested at a certain stage or turns the wrong way round. Even first year residents are familiar with right sided aortic arch, azygos lobe and accessory ossification centres. Over time, one encounters a whole array of normal variants and learns to interprete them as such. Of course, one can only identify, what one has learnt to see and there is a large spectrum of slight developmental abnormalities, which should not be misdiagnosed as abnormality in need of further imaging, invasive diagnostic procedures or treatment. On the other hand, some developmental disorders have clinical significance and you could be the first to advise the patient.

Below, we are pleased to present the best submissions for the “Normal variant or disease” interlude at ECR 2018:
