Abstract

Three adult patients are described with sonographic features of subfascial fat hernation. Each patient presented to the musculoskeletal ultrasound department at our institution for the evaluation of a palpable mass of the low back. Subfascial fat hernation, also known as back mice and fibro-fatty nodule, are an uncommon cause of a palpable mass in the low back or low back pain. They are small mobile subcutaneous nodules in a characteristic location near the posterior superior iliac spine. This entity has not been described in the radiology literature. These cases are presented in order to demonstrate the sonographic findings of back mice and to describe key anatomic features.
