The fascial tail sign is the linear extension along the fascia/muscular aponeurosis from a deeper tumor, typically seen in desmoid tumors.
It can be seen in other soft tissue tumors containing collagen fibers such as
It is also a characteristic sign in nodular fasciitis.
It appears as a tail and is best appreciated on MRI, classically seen in desmoid tumors as T2 hypointense bands that progressively enhance particularly on delayed phases. The low signal intensity is due to its collagen content.
