Inverted papilloma case. ( A, B ) coronal T1WI & coronal T1W gadolinium-enhanced MR images show heterogeneous enhancement of the lesion “well enhancing stroma and less enhancing epithelium that create convulated cribriform pattern.” ( C ) Axial DW image with b- value 1000 second mm ² shows low signal intensity of the lesion denoting facilitated diffusion. ( D ) Axial ADC map image with b-value of 1000 second/mm ² shows high signal intensity of the lesion denoting facilitated diffusion with ADC value is 1.51 × 10–3 mm ² / s.
