Interrupted IVC with azygos continuation can mimic mediastinal lymph node enlargement on unopacified CT scans, highlighting the importance of contrast-enhanced imaging to avoid misdiagnosis.
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.
