Does That Go There? A Rare Occurrence of Spontaneous Sternocleidomastoid Abscess without Trauma in a Diabetic Individual.

BACKGROUND Spontaneous abscesses are generally typical in patients with significant risk factors and have been linked to numerous muscle groups. The sternocleidomastoid muscle, however, piqued our interest as an unusual location, especially in this patient who, other than diabetes mellitus, had no associated risk factors or signs of trauma.
