[A 'Trivial' Angina with Serious Consequences].

Area of Science:

• Infectious Diseases
• Vascular Medicine
• Critical Care Medicine

Background:

• Pharyngitis is a common infection, typically treated symptomatically or with antibiotics if bacterial.
• Lemierre's syndrome, a septic thrombophlebitis of the internal jugular vein, is a rare but severe complication of oropharyngeal infections.
• Early recognition and management are critical due to high morbidity and mortality rates.

Observation:

• A 21-year-old male presented with septic shock two weeks post-pharyngitis.
• Clinical presentation included internal jugular vein thrombosis, septic systemic metastatic lesions, and bacteremia.
• Causative agent identified as Fusobacterium necrophorum.

Findings:

• Diagnosis of Lemierre's syndrome was confirmed based on the clinical and microbiological findings.
• The case highlights the potential for severe systemic complications from seemingly minor throat infections.
• Fusobacterium necrophorum was identified as the responsible pathogen, emphasizing its role in this syndrome.

Implications:

• This case underscores the importance of considering Lemierre's syndrome in patients with persistent or severe pharyngitis, even with negative streptococcal tests.
• Early and aggressive antibiotic therapy is essential for managing Lemierre's syndrome and preventing embolic complications.
• Physicians should be vigilant for 'red flag' symptoms associated with pharyngitis that may indicate a higher risk of developing this serious condition.
