Patient Data
Age: 50 years
Gender: Female
Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.
From the case:
Hypertrophied column of Bertin
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/17085/annotated_viewer_json?lang=us"}
Note that the hypertrophied column is seen to enhance just like normal parenchyma in all phases, there is no mass effect.
Case Discussion
This is a common cause of renal "pseudomass". On ultrasound the column splits the sinus echoes.
CECT is often done to resolve the issue. A hypertrophied column shows enhancement that is the same as normal cortex. It merges with the cortex and causes no contour deformity. These findings help to differentiate it from other pseudomasses such as fetal lobulation and a dromedary hump.
