Abstract

We present a patient with idiopathic intracranial calcifications with simultaneous involvement of sclera, choroid, optic nerve, and trochlear apparatus. A 70-year-old woman with bilateral decreased vision was referred to our hospital. Ocular examinations revealed sclerochoroidal mass beneath superotemporal vascular arcade in macular area. Orbital CT scan shows bilateral calcification of dural optic nerve sheath and posterior wall of the globe as well as calcification in the trochlear apparatus and brain. Ultrasound showed highly reflective echogenic lesion with shadowing. OCT revealed rolling topography with thinning of the overlying choroid and outer nuclear layer as well as absence of the external limiting membrane and inner segment-outer segment junction. Slight irregular thickening of the retinal pigment epithelium is present. It is the first case of simultaneous bilateral dural optic nerve sheath and sclerochoroidal calcification.
