Axial contrast enhanced CT in arterial phase demonstrates a 2.5 cm pseudoaneurysm arising from the right common femoral artery. There is a associated with a large retroperitoneal hematoma displacing the urinary bladder to the left. Incidentally there a large right ovarian cyst. Hyperdense material in the gallbladder indicates vicarious excretion of contrast (from the previous coronary angioplasty procedure)
This patient developed a false aneursym at the puncture site ie right common femoral artery. The puncture site is suprainguinal and perhaps post procedure compression was suboptimal contributing to this complication.
