PA chest radiograph (a) demonstrates the placement of a right-sided chest port, with the catheter tip near the cavoatrial junction. Coronal CT (b) done shortly after demonstrates the same catheter, with some motion artifact.

After multiple transfusions, he was transferred to our tertiary care facility, where a comprehensive workup including lymph node biopsy and flow cytometry yielded a diagnosis of T-cell predominant acute lymphoblastic leukemia, and he began treatment with chemotherapy involving the use of a right-sided chest port with right internal jugular vein access (Figure 1).
Chest CT ordered to evaluate for pulmonary fungal disease revealed proper placement of a left-sided chest port and a calcified tubular structure (arrows) representing a calcified CRS near the junction of the right brachiocephalic vein and superior vena cava on axial (a) and coronal (b) views.

The CT was negative for signs of infection or inflammation but incidentally demonstrated a calcified tubular structure with a cross-sectional diameter of approximately 2 mm, likely representing a CRS, at the junction of the right brachiocephalic vein and superior vena cava (Figure 2).
Follow-up chest CT approximately 10 months after the initial discovery of the calcified CRS demonstrates its migration to the distal right pulmonary artery (arrows) on axial (a) and coronal (b) views.

CT was performed to evaluate for pulmonary source of infection. CT demonstrated migration of the calcified CRS to the distal right main pulmonary artery (Figure 3).
