Why did you select this case for submission?
I selected this case because it demonstrates the imaging appearances of a rare condition.
What should readers learn from this case?
Readers should learn an awareness of this entity, CAPNON, its different imaging appearances, and differential diagnosis considerations.
What did you learn from working on the case?
I learned to consider this rare entity in the differential diagnosis of an extra medullary spinal axis calcified lesion, and about the differentiating features of CAPNON from more common diagnoses, such as meningioma.
How did guidance from senior staff at your institution impact your learning and case development?
My senior staff urged me to consider the diagnosis and plan the needed diagnostic work-up. They referred me to a number of scientific articles on the topic.
Why did you choose Case in Point for submission of your case?
ACR’s Case In Point has an excellent reputation.
What is the appeal of online learning tools such as Case in Point as opposed to print learning venues?
Online learning is a great privilege for radiologists during all stages of their career. It provides simple, to-the-point brain teasers, and accessible references to a wide range of complex work experiences.
Are you a regular reader of Case in Point? What are your favorite types of cases?
Yes I am. My favorites are the neuroradiology cases.
What else should we know about the case that you'd like to share?
A pattern recognition approach should be the first step in image readings. Secondly, the most appropriate diagnoses and differential diagnoses should be built upon the first step. Common things are common, and do apply. However, awareness of inclusion and exclusion features of different diagnostic possibilities can lead to a safer diagnosis without unnecessary intervention.
