Insights
Computed tomography (CT) and ultrasound accurately diagnosed internal jugular vein thrombosis in six patients, often missed by initial clinical assessments. Delayed presentation and varied causes highlight the importance of imaging for this condition.
Area of Science:
- Radiology
- Vascular Imaging
- Diagnostic Medicine
Background:
- Internal jugular vein thrombosis (IJVT) can present with subtle and non-specific clinical signs.
- Delayed medical attention is common in IJVT cases, leading to diagnostic challenges.
Purpose of the Study:
- To evaluate the diagnostic accuracy of computed tomography (CT) and ultrasound in identifying internal jugular vein thrombosis.
- To highlight the spectrum of causes and clinical presentations of IJVT.
Main Methods:
- Retrospective analysis of six patients (aged 14-83 years) diagnosed with IJVT via CT.
- Review of clinical presentations, provisional diagnoses, and identified causes.
- Correlation of CT findings with ultrasound results in four patients.
Main Results:
- CT revealed characteristic findings: distended veins, enhancing walls, intraluminal filling defects, and soft tissue swelling.
- Ultrasound demonstrated distended, nonpulsatile veins with internal echoes.
- Initial clinical diagnoses were incorrect in all cases, with differentials including abscess and neoplasm.
- Identified causes included venous catheters, malignancy, infective adenopathy, and polycythemia.
Conclusions:
- CT and ultrasound are reliable and accurate modalities for diagnosing internal jugular vein thrombosis.
- The subtle clinical presentation of IJVT necessitates a high index of suspicion.
- Radiologists may encounter more unsuspected IJVT cases due to non-specific clinical findings.
Abstract:
Six patients, aged 14-83 years, were shown by computed tomography (CT) to have thromboses of the internal jugular vein. In all cases, medical attention was sought only after a delay (4-21 days). In no case was the provisional clinical diagnosis correct, with working diagnoses ranging from abscess to neoplasm. A wide variety of likely causes was discovered, including venous catheters, local malignancy, infective cervical adenopathy, and polycythemia. CT showed distended veins with enhancing walls, low-attenuation intraluminal filling defects, and swelling of the adjacent soft tissues. Four of the six patients also underwent ultrasound examinations, which showed the veins to be distended and nonpulsatile, with internal echoes. Both modalities proved reliable and accurate. Because of the subtle and often non-specific clinical findings, it is likely that more clinically unsuspected cases will be encountered by the radiologist.
