Patient: Male, 52-year-old
Final Diagnosis: Gas gangrene in the deep neck spaces with
Klebsiella pneumoniae
septicemia
Symptoms: Painful swelling of the right-sided neck associated with spiking fever, confusion and dyspnea
Clinical Procedure: Neck exploration for drainage
Specialty: Otolaryngology
Objective:
Rare disease
Background:
Gas gangrene is a rapidly progressive and potentially fatal infection that is common in the extremities. Gas gangrene of the head and neck is a very rare condition, and non-clostridial gas-forming neck abscess caused by
Klebsiella pneumoniae
is unusual. This report is of a diabetic man with poor dental hygiene, a right dental abscess, and parapharyngeal abscess with gas gangrene due to
Klebsiella pneumoniae
infection, presenting with septic shock and multiorgan failure, who recovered after surgical neck debridement.
Case Report:
A 52-year-old man with diabetes mellitus lost consciousness and collapsed on a curbside. He presented with painful swelling of the right-side neck, associated with spiking fever, confusion, dyspnea, and stridor. He had right submandibular and supraclavicular swelling with crepitus, multiple dental caries, and multiorgan dysfunction, and was intubated. A computed tomography scan showed a gas-forming abscess in the right parapharyngeal, retropharyngeal, and paralaryngeal spaces and dense infiltration with pleural effusion in the upper lobes. Neck exploration was performed for drainage. Necrotic tissue and foul-smelling pus were debrided and drained. Gram stain showed gram-negative bacilli. Necrotic tissue, pus, and blood culture showed
Klebsiella pneumoniae
. He remained on intravenous meropenem for 14 days and was frequently debrided with irrigation until the infection subsided. Finally, normal physiologic functions of the failing organ system were restored.
Conclusions:
We present a rare case of
Klebsiella pneumoniae
infection causing gas gangrene in the deep neck spaces, leading to septic shock and multiorgan failure, who recovered after surgical neck debridement. This is a potentially fatal condition that requires emergency drainage because of its high mortality rate.
