Computed Tomographic Dacfyocystography using Rayvist(R)

ABSTRACT

The combination of dacryocystography and computed tomography have been called as computed tomographic dacryocystography. The authors carried out computed tomographic dacryocystography using water soluble contrast media, Rayvist(R), in two patients with a mass around the lacrimal fossa. This radiologic technique demonstrated that the lacrimal system was not invaded by the tumor and was helpful in planning the surgical approach. The results of excisional biopsy of the mass revealed an epidermoid cyst in both cases.
