Image-guided transoral biopsy in a Grisel’s syndrome. Case report

Grisel’s syndrome is a disease characterized by an atlanto–axial rotatory subluxation following acute inflammation of the upper respiratory tract. The syndrome has a good prognosis as it usually heals with antibiotics, despite the delayed serious complications that have been reported. When neuroradiological investigation does not allow an accurate differential diagnosis between a tumor and osteomyelitis, an image-guided transoral biopsy is a safe, fast, minimally invasive, as well as effective, procedure.
