Fascial tail sign

The fascial tail sign is the linear extension along the fascia/muscular aponeurosis from a deeper tumor.

Radiographic features

It appears as a tail and is best appreciated on MRI, classically seen in desmoid tumours as T2 hypointense bands that progressively enhance particularly on delayed phases. The low signal intensity is due to its collagen content. It can be seen in other soft tissue tumours containing collagen fibers such as fibrosarcoma,  leiomyoma, and neurofibroma. It is also characteristic sign in nodular fasciitis.
