title: Leptomeningeal cyst of the orbit presenting with pulsatile exophthalmos.
abstract: The case of a 64-year-old man who presented with unilateral pulsatile exophthalmos is described. A defect in the supero-medial wall of the orbit and an extraconal low density mass were demonstrated by orbital radiographs and CT. Positive contrast CT cisternography confirmed the diagnosis of a leptomeningeal cyst.
