Unusual Case of Torticollis

A 1-year-old girl is presented with progressive torticollis over the last few days.
She seems in good clinical condition, afebrile, with possible difficulty to swallow (she stopped eating from the table and returned to mashed food). In the clinical examination most remarkable is a nuchal muscular rigidity and restricted movements of her head to both sides as well as upwards.

At the initial work-up CRP is 90mg/l, Lc 11.8/mcl; Hgb 106g/l, Plt 642/mcl

Due to a lack of MRI slots you decide to order a lateral x-ray of the cervical region
