We report a case of interrupted inferior vena cava with azygos continuation diagnosed as a isolated finding in a patient with lung carcinoma. Findings of the unopacified CT scan initially simulated a paraesophageal lymphadenopathy. The contrast - enhanced spiral CT scan showed a dilated azygos vein in the absence of definable inferior vena cava.

Case Summary

Background: The azygos venous system is an accessory venous pathway supplying an important collateral circulation between the superior and inferior vena cava (IVC).  Case summary: We report a case of complicated community-acquired pneumonia with interruption of the IVC with azygos continuation that was misdiagnosed as lung neoplasm.  Discussion: The aim of this case report is to emphasize the importance of recognizing an enlarged azygos vein at the confluence with the superior vena cava and in the retrocrural space to avoid misdiagnosis as a right-sided para-tracheal mass. The angiographic features and clinical importance of this condition are discussed.

Azygos Continuation

The azygos system enlarges in cases of obstruction to the superior vena cava or inferior vena cava and result in increase blood flow through the system. Azygos continuation of the inferior vena cava is usually congenital and asymptomatic. The azygos vein is the sole drainage of the blood from the lower half of the body to the heart. It is crucial to identify the anomaly as it might involve in the surgical planning of tumours in the thorax or abdomen. Computed Tomography is a non-invasive technique and provide important information about the tumour and the vascular anomaly.

Left Subclavian Vein

Without the femoral venous approach, transcatheter closure of an atrial septal defect is challenging. We performed percutaneous closure via the left subclavian vein in a patient with absence of the inferior vena cava with azygos continuation. Considering that inferior vena cava anomalies are not extremely rare among those with congenital heart disease, the left subclavian vein approach can be an alternative to the femoral approach.

Common Benign Tumour

Hepatic haemangioma (HH) is a common benign tumour of the liver and is usually asymptomatic. HH causing isolated right-sided pleural effusion and bilateral pedal oedema due to inferior vena cava (IVC) compression have never been reported in the literature. We report a 35-year-old male patient who presented with breathlessness and mass per abdomen. On examination, the patient was found to have right-sided pleural effusion, bilateral pedal oedema, hepatomegaly. Contrast-enhanced CT showed compression of the IVC by the HH. The patient was managed with right-sided intercostal drain insertion for pleural effusion and hepatic artery embolisation. The patient improved gradually with reduced pleural effusion and resolving pedal oedema.

Study Population

Objective: To determine the prevalence of inferior vena cava (IVC) anomalies in Thai patients who underwent contrast-enhanced computed tomography (CT) of the abdomen. Materials and Methods: Two radiologists retrospectively and independently reviewed the contrast-enhanced abdominal CT examinations in 1,429 Thai patients between August 1, 2018 and January 25, 2019 who met the inclusion criteria. Patients were included, if (a) their CT showed well visualized IVC, renal veins, and right ureter that were not obliterated by tumor, cyst, fluid collection, or intraperitoneal free fluid, (b) they had not undergone previous abdominal surgery that altered anatomical configuration of the IVC, renal veins, and right ureter. The presence of all IVC anomalies were recorded. Results: Among the 1,429 studied patients, 678 were male (47.4%) and 751 were female (52.6%). The prevalence of IVC anomalies was 3.5%. Five types of IVC anomalies were presented. The most common was circumaortic left renal vein in 24 patients or 48.0% of all IVC anomalies and 1.7% of the study population, followed by retroaortic left renal vein in 15 patients or 30.0 % of all IVC anomalies and 1.0% of the study population. Other IVC anomalies included double IVC, left IVC, and retrocaval ureter at 0.5%, 0.2%, and 0.1% of the study population, respectively. Conclusion: The prevalence of IVC anomalies in the present study differed from the previous studies conducted in other countries, which may be attributable to differences in race and ethnicity. Awareness of these anomalies is essential when evaluating routine CT examinations in asymptomatic patients. Their presence should be carefully noted in radiology reports to avoid anomaly-related complications.
