Authors: C. Eric Gullbrand, DO PGY-1, Radiology Resident, Department of Diagnostic Radiology, Christiana Care Health System, Newark, DE; Kristina A. Siddall, MD Associate Program Director, Department of Diagnostic Radiology, Christiana Care Health System, Newark, DE

Why did you select this case for submission?

Tubular adenomas are rare benign breast neoplasms with an overall incidence ranging from 0.13-1.17% of benign breast lesions. Dr. Siddall and I chose to submit this case as a review of the classic sonographic findings for tubular adenomas.

What should readers learn from this case?

Sonographic evaluation most commonly reveals a well-circumscribed, hypoechoic mass. This is usually effective in confirming the benign nature of the lesion.

What did you learn from working on the case?

Histopathological evaluation of tubular adenomas is currently the gold standard for diagnosis. Clinical, radiologic, and cytological preoperative diagnosis can be unreliable.

How did guidance from senior staff at your institution impact your learning and case development?

Dr. Siddall pointed me in the right direction in order to obtain additional information about differential considerations and imaging findings. At Christiana, senior staff members expose residents to many unusual cases and provide helpful teaching points.

Why did you choose Case in Point for submission of your case?

Case in Point is a fantastic resource for providing concise information about a variety of interesting cases. As this was a relatively rare case that had not been previously described in the CIP archives, we felt this might be a compelling submission.

Are you a regular reader of Case in Point? What are your favorite types of cases?

I review CIP cases regularly in order to learn about interesting cases and to test my current knowledge base. The musculoskeletal cases are usually my favorite.

Is there anything else you’d like readers to know about your case?

Tubular adenomas most commonly affect young women of reproductive age and present as firm, mobile, painless breast masses. Sonographic findings can be very helpful in differentiating benign from malignant breast lesions.
