A left orbital intra-conal soft tissue mass lesion is seen replacing the retro-orbital fat and showing the following features, extension and relations:
- it appears isodense (as compared to the extra-ocular muscles) with few calcific foci seen within. In the post-contrast series, it shows homogeneous enhancement with non-enhancing optic being circumstantially encased by the aforementioned lesion (giving tram track sign in the axial images and dot sign n the coronal images).
- it measures about 3.3 x 2.2 x 1.8 cm along its axial and CC dimensions respectively.
- it causes subsequent eye proptosis.
- it is seen abutting the left eye globe, yet no evidence of invasion.
- it is seen extending posteriorly till the orbital apex.
- medial bowing of the lamina papyracea and rarefaction of the superior orbital wall, yet no evidence of cortical beach.
