A patient with a large cystic mass in the right frontotemporal lobe underwent surgery. A T1-weighted axial and B T1-weighted sagittal MRI with contrast demonstrated a cystic mass located at the right frontotemporal lobe. C 3D reconstruction imaging showed the right middle cerebral artery was displaced and encased by the mass. D 3D reconstructed images also revealed the encased sylvian vein. E, I The mass was removed via a pterional approach and the sylvian vein (arrow) was preserved, FL ICG-VA integrated with FLOW 800 confirmed the patency of the sylvian vein, and semiquantitatively analysed the blood flow of the protected vein
