CTICasesFlipped subcutaneous port
Imaging findings
Chest radiograph shows inversion of a triangular PowerPort port, with the alphanumeric 'CT' lettering presenting as a mirror image, indicating that the port has flipped over under the skin.
Key takeaways
Subcutaneous ports can flip over within a large or loose subcutaneous pocket. Flipped ports cannot be accessed normally because the needle hits the metallic backing rather than the septum. Recognizing mirror-image orientation of radio-opaque port letters indicates port inversion.
