Streptococcal meningitis complicating diagnostic myelography: three cases and review
1Department of Medical Education, Methodist Hospitals of Memphis, Tennessee, USA.
Abstract:
Bacterial meningitis is a rare complication of myelography. Most reported cases are due to miscellaneous streptococci, but the source of these organisms is uncertain. The differential diagnosis of chemical meningitis caused by the contrast material vs. bacterial meningitis may be difficult. We recently treated three patients with streptococcal meningitis following myelography performed with the contrast medium iopamidol. We discuss the diagnostic and therapeutic approach to postmyelography meningitis.
Insights
Bacterial meningitis after myelography is rare but challenging to diagnose. This study highlights three cases of streptococcal meningitis following iopamidol myelography, emphasizing diagnostic and treatment strategies.
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- Myelography, a diagnostic imaging procedure, carries a rare risk of complications.
- Bacterial meningitis following myelography is an uncommon but serious concern.
Observation:
- Three patients developed streptococcal meningitis after undergoing myelography with the contrast agent iopamidol.
- Distinguishing bacterial meningitis from chemical meningitis induced by contrast media can be diagnostically challenging.
Findings:
- Streptococci were identified as the causative agents in these post-myelography meningitis cases.
- The source of streptococcal infection in these instances remains uncertain.
Implications:
- Early recognition and appropriate antibiotic therapy are crucial for managing post-myelography meningitis.
- Further research may be needed to elucidate the source of infection and optimize preventative measures.
