RT Journal Article SR Electronic T1 Delayed diagnosis of odontoid peg osteomyelitis with bilateral X and XII cranial nerve palsies JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e227943 DO 10.1136/bcr-2018-227943 VO 12 IS 3 A1 Faisal Bashir Chaudhry A1 Samavia Raza A1 Usman Ahmad YR 2019 UL http://casereports.bmj.com/content/12/3/e227943.abstract AB Upper cervical osteomyelitis is rare. Its presenting features are fever and neck pain, but rarely it can involve lower nerves. MRI is the main imaging modality, but it is difficult to interpret due to the unique anatomy of C1 and C2 vertebra and complex intervertebral joint. We describe a case of a 67-year-old woman, who presented with the complaint of loss of voice, neck pain and fever for 5 days. Despite repeated imaging of neck, the diagnosis was not reached. As the patient’s condition continued to deteriorate, clinical signs of bilateral 10th and 12th cranial nerve paralysis appeared and lead to a focused workup for base of skull pathology. Discussion with the radiologist helped guide the imaging protocol, which leads to the correct diagnosis being made. Treatment was tailored by blood cultures and available images. Temporary immobilisation with a cervical collar and a total of 12 weeks of antibiotics lead to complete remission.
