Case report
A 43-year-old patient without noteworthy antecedents consulted his attending physician
for dysphagia and diffuse cervical pain that has been evolving for three days. The patient
◦
was sub-febrile (38 C). The clinical examination detected stiffness of the neck without
neurological disorder. The ORL examination did not detect any significant anomaly, in
particular in the tonsil region. The lab tests revealed mild hyperleukocytosis (12,000 GB/L)
with neutrophils (11,000 G/L) and an ascension or C-reactive protein (60 mg/L). A cervical
scan with the injection of iodine-based contrast products was carried out (Figs. 1 and 2).
