Abstract:
The injection of drugs into the neck is unusual and thrombosis of the internal jugular vein can be a rare clinical presentation with a high risk for severe complications. We report a case of a 31-year-old male intravenous drug user presenting with fever, shortness of breath and right neck oedema. Laboratory studies revealed elevated inflammation parameters. X-ray imaging revealed a broken syringe needle inside the soft tissues of the neck. Computed tomography (CT) scans of the thorax and brain were unremarkable, while cervical CT showed a fully thrombosed, right internal jugular vein. Intravenous antibiotics were initiated, and modified after identification of an anaerobic Gram-negative oropharynx-derived pathogen (Fusobacterium necrophorum). The patient was discharged after resolution of symptoms under treatment. Septic internal jugular vein thrombosis should always be included in the differential diagnosis of local neck inflammation and systemic sepsis in intravenous drug users. Prompt and aggressive antibiotic treatment is vital, whereas the role of anticoagulation therapy is not definitely known.
Insights
Intravenous drug users presenting with neck swelling may have internal jugular vein thrombosis. Prompt antibiotic treatment is crucial for this rare but serious condition.
Area of Science:
- Internal Medicine
- Infectious Diseases
- Radiology
Background:
- Internal jugular vein thrombosis (IJVT) is a rare complication, particularly in intravenous drug users (IDUs).
- Neck trauma or infection can lead to IJVT, posing risks of severe complications like sepsis and pulmonary embolism.
Observation:
- A 31-year-old male IDU presented with fever, dyspnea, and right neck edema.
- Radiographic imaging revealed a retained foreign object (broken syringe needle) in the neck.
- Cervical CT confirmed complete thrombosis of the right internal jugular vein.
Findings:
- Blood tests indicated elevated inflammatory markers.
- The patient was diagnosed with septic IJVT caused by *Fusobacterium necrophorum*, an oropharynx-derived pathogen.
- Cervical CT confirmed complete thrombosis of the right internal jugular vein.
Implications:
- Septic IJVT should be considered in IDUs with neck inflammation and systemic sepsis.
- Aggressive intravenous antibiotic therapy is vital for managing this condition.
- The optimal role of anticoagulation in septic IJVT remains uncertain and requires further investigation.
