Mentions: USG revealed a well-encapsulated, compressible, echogenic mass lesion (approximately 2.8 × 1.7 cm in size) situated superomedially in the extraconal space of the left orbit. On Doppler, the mass showed multiple vascular channels (both arterial and venous channels) suggestive of a vascular lesion [Figure 1]. Small low-flow feeding arteries were seen. MRI showed an oval, encapsulated, superomedial, and extraconal mass in the left orbit. The mass appeared isointense to orbital muscle on T1W [Figure 2] and mildly hyperintense to orbital muscle on T2W [Figure 3] images, with intense enhancement on post-gadolinium scans [Figure 4a and b]. There was lateral displacement of the medial rectus muscle anteriorly with inferolateral displacement of the globe. The intraocular muscles and optic nerve sheath complex showed normal signal intensity.
Extraconal cavernous hemangioma of orbit: A case report
Bottom Line: Cavernous hemangioma is the most common benign noninfiltrative neoplasm of the orbit.Most cavernous hemangiomas are intraconal and lateral in location.We present a case of a cavernous hemangioma with an unusual extraconal and superomedial location.
