1 Evolution of imaging for internal auditory canal CPA cistern masses.
Evolution of imaging for internal auditory canal CPA cistern masses. A, Frontal view from an iophendylate cisternogram shows a round filling defect (black arrowheads) within the left IAC (white arrows). The distal vertebral and basilar arteries can be seen outlined by contrast (black arrows). B, An air-CT cisternogram obtained with the patient in the decubitus position after injecting 5 mL of air via LP shows a mass in the right IAC extending into the CPA cistern (arrow). E.G.
