Abstract

|
|
|
Thyroid-associated ophthalmopathy is associated with thyroid dysfunction, particularly Graves` disease, and is manifested as eye signs, including proptosis. In cases of unilateral exophthalmos with thyroid-associated ophthalmopathy, other causes such as orbital neoplasm, carotid-cavernous fistula, cavernous sinus thrombosis, and dural arteriovenous malformation (AVM) should be excluded. Dural AVM, an abnormal dural arteriovenous connection, is a rare neurovascular entity that mimics thyroid-associated ophthalmopathy. When eye involvement is unilateral or asymmetric, dural AVM can be considered in the differential diagnosis of thyroid-associated ophthalmopathy. A twenty-six year-old woman presented with unilateral exophthalmos in Graves` disease. By orbital magnetic resonance imaging and cerebral angiography, thyroid-associated ophthalmopathy and dural AVM were diagnosed. The unilateral exophthalmos improved after coil embolization of the dural AVM. In summary, we report the first case of a dural AVM with Graves` disease and thyroid-associated ophthalmopathy.
