We evaluated the clinical value of magnetic resonance imaging (MRI) in 9 cases of parasinus mucocele. The series included frontal mucocele 1 case, frontal and anterior ethmoidal mucocele 3 cases, anterior mucocele 2 cases, posterior eth-moidal mucocele 2 cases, and maxillary mucocele 1 case. MRI was performed with proton density P (300), inversion recovery IR (1000, 350), and spin echo SE (1000, 60/90) with 0.1 tesla resistive con-ducting system, or with T1-weighted SE (440,40),IR (1500, 500) and T2-weighted SE (1500, 500) with 0.5 tesla superconducting system.

We obtained images of variable intensities when employing P, IR and T1 -weighted SE imaging. It was possible to differentiate mucocele from normal orbital tissue by comparison with T2-weighted imaging. All the 9 cases manifested a high intensity of T2,-weighted images. The findings were sugges-tive of a possibility to verify the content to par-asinus cysts by MRI findings.
