There is a thick walled collection in the right lower neck. This appears to be anterior to (without infiltration into) the thyroid gland and extends into the upper mediastinum posterior to the right sternoclavicular joint. There is a 13 x 26 x 25 mm liquefied component. Surrounding granulation tissue is seen extending into the superior mediastinum in the pretracheal region and right carotid space. Sternoclavicular joints appear unremarkable. There are no features of osteomyelitis or disciitis in the cervical or upper thoracic spine.
