Episacral lipoma - "back mouse"
Discussion:
"Back mice" can be difficult to diagnose and are often missed. This patient had received many back pain investigations, including a full-body MRI.
However, no test had been diagnostic until the ultrasound study had revealed a definite mobile fat lump. Following this, the MRI confirmed the diagnosis. Again, MRI diagnosis being used to confirm back mice has been established 1.
