Masses mimicking PLSVC. ac Axial (a, b) and coronal-oblique reformated (c) CT images depict a neurofibroma (red arrows) arising from the left phrenic nerve, which has a parallel course with the pericardiophrenic vein, in a patient with neurofibromatosis type 1. If the beginning/end of the mass and relationship with vascular structures are not carefully evaluated, it can be confused with PLSVC due to its location. df Axial CT images depict multiple mediastinal hypervascular lymphadenopathies (blue stars) in the patient with renal cell carcinoma. Hypervascular lymphadenopathies in the left half of the mediastinum (red arrows) may mimic PLSVC. Green arrows show RSVC
