Discussion

X-ray of the hand with diffuse fusiform soft-tissue swelling of the entire 3rd digit. This sign refers to fusiform soft-tissue swelling involving an entire, single digit within the hand. The appearance of a sausage digit (cocktail sausage) is classically associated with the single-ray pattern of involvement seen in some patients with psoriatic arthritis, and may be the initial manifestation of the disease.
