[Cervicofacial cellulitis complicated by internal jugular vein thrombosis]

Area of Science:

• Dermatology
• Infectious Diseases
• Radiology

Background:

• Cervicofacial cellulitis (CFC) is a frequent dermatological emergency with significant morbidity.
• Early diagnosis and management are crucial to prevent severe complications.

Observation:

• A case of a 31-year-old male with parotitis and worsening CFC despite initial treatment is presented.
• Cervicofacial CT revealed left internal jugular vein thrombosis (IJVT).
• Initial bacteriological samples were negative, and chest imaging showed no pulmonary lesions.

Findings:

• The patient received antibiotics and anticoagulants for 6 weeks, leading to a favorable outcome.
• Internal jugular vein thrombosis (IJVT) is an uncommon but serious complication of CFC.
• IJVT can occur independently or as part of Lemierre's syndrome.

Implications:

• Contrast-enhanced CT scans are essential for evaluating CFC extent and detecting complications like IJVT.
• Suspected IJVT in an infectious context necessitates screening for septic emboli, particularly pulmonary emboli.
• Identifying IJVT, especially with ENT infections, warrants investigation for Lemierre's syndrome.
