case_images: Coronal T1WI showing nodular enlargement of (a) the right superior oblique muscle and inferior rectus, as well as (b) the right lateral rectus, left lateral rectus, and medial rectus. The enlarged EOMs exhibited isointensity to cerebral white matter

case_images: ARSR-11-0002F3
case_images: T2-weighted images (Fig. 2). The muscle borders were well-defined, and there was mild-to-significant heterogeneous contrast enhancement with gadolinium (Fig. 3). The tendons were seen to be spared, and there was no evidence of orbital bone marrow involvement.
case_images: The right superior oblique muscle tumor was positive by immunoperoxidase staining for AFP (x100)
