Fatal Cervical Spinal Epidural Abscess and Spondylodiscitis Complicated With Rhombencephalitis Caused by Klebsiella pneumoniae: A Case Report and Literature Review

Spinal epidural abscess (SEA) is a rare but sometimes life-threatening condition. The principal organisms in SEA and spondylodiscitis are gram-positive bacteria, e.g., Staphylococcus aureus and Streptococci. Spontaneous gram-negative SEA and spondylodiscitis especially Klebsiella pneumoniae are very rare. We report a 71-year-old Thai male with diabetes, presenting fever, enlarged neck mass, and progressive painful swallowing a week before admission. MRI of the whole spine demonstrated epidural abscess along the anterior thecal sac from C2 to C7 levels with spinal meningitis; multiple rim-enhancing lesions at the left sternocleidomastoid/levator scapulae, splenius capitis, semispinalis capitis, and bilateral scalene muscles; and rhombencephalitis with brain abscess. Klebsiella pneumoniae was isolated from blood culture. CT of the whole abdomen showed unremarkable intra-abdominal lesion. Intravenous ceftriaxone was administered, but the patient was unable to undergo surgical drainage due to unstable condition and died after two weeks of admission. Spontaneous SEA and spondylodiscitis caused by K. pneumoniae are very rare but sometimes fatal. In the case of SEA and spondylodiscitis, even when K. pneumoniae is uncommon, it should be also considered as a pathogen, especially when the patient had important risk factors.
