Abstract:
A 57-year-old man presented with odynophagia for 1 week was referred for FDG PET/CT scan to rule out recurrent hypopharyngeal cancer. The FDG PET/CT showed hypermetabolic lesions in hypopharyngeal area and adjacent cervical spine with pneumorrhachis, the presence of intraspinal air, on attenuation CT images, which might indicate a life-threatening infection. An emergency MRI confirmed the presence of cervical spondylodiscitis with an epidural abscess. The patient rapidly progressed to quadriplegia and difficulty voiding on the same day as the PET/CT scan, leading to emergent operation. The patient received antibiotics treatment and discharged 4 months later without evidence of cancer recurrence.
