Fig. 4

A 35-year-old female patient with acute rhino-sinusitis presented with left-sided orbital pain, mild proptosis and limited orbital movement. Axial T1- and T2-weighted images of the left orbit A, B show a primarily extraconal mass involving the left medial rectus muscle with intraconal extension. No diffusion-weighted restriction seen on DWI (b500) image (C) and ADC (D). The ADC value for the mass is 1.09 × 10−3 mm2/s. Histopathologically proved left-sided orbital inflammatory pseudotumor by FNAC
