Evaluation of a small tumor (< 2 cm) (A-D) A female between the ages of 50 and 60 diagnosed with meningioma on the right side of the MC and parasellar region. A Postcontrast T1WI image showing a 1.2 cm enhancing tumor at the right MC. For the present small tumor, the appearance of the dura tail was not clearly identified. B, C Restricted diffusion in the DWI/ADC sequence in small tumors (in the parasellar region). D In the axial T1WI image, no significant masticatory muscular atrophy was identified. E-I A female between the ages of 50 and 60 diagnosed with a schwannoma on the right side of the MC. E In the postcontrast T1WI image, a 1.4 cm enhancing tumor at the right MC. F On T2W images, cystic changes were not clearly identified in such small schwannomas. G, H No restricted diffusion in the DWI/ADC sequence. I In the axial T1WI image, no significant masticatory muscular atrophy was identified
