Convoluted cerebriform pattern

A convoluted cerebriform pattern is a term used to denote the appearance of an sinonasal inverted papilloma on MRI. The appearance is seen on both T2 and post contrast T1 images and appears as alternating roughly parallel lines of high and low signal intensity.

This sign has been reported as present in 50-80% of cases, whereas it is uncommon in other sinonasal tumours (<20%) 1.
