Use of Contrast Radiography to Differentiate Unilocular Cystic Lesion from Multilocular One - A Case Report

Abstract

Contrast Radiography is a X-ray procedure that uses a special substance; a contrast medium to highlight tissues and organs that would not be visible otherwise. In the past attempts have been made to detect and to see the extent of tumours in nasopharynx using contrast radiography. X ray contrast radiography of a cystic lesion is not reported yet to the best of our knowledge. The radiographic appearance of cystic lesions in jaws may be illusive especially in maxilla owing to the superimpositions by normal anatomic structures. Unilocular or multilocular appearance of lesion has a lot of significance in radiology as radiographic diagnosis may change accordingly. In the present case we performed contrast radiography of an apparently multilocular cystic lesion. For this procedure we used Urografin 76% (aqueous solution of 0.1 g sodium amidotrizoate and 0.66 g meglumine amidotrizoate (sodium diatrizoate and meglumine diatrizoate) as a contrast agent. The technique we demonstrated is a chair-side technique which can be used to differentiate between unilocular and multilocular lesions of the jaws. It also contributes in locating the lesion and determining its extent. It is a cost effective technique which can narrow down the range of differential diagnosis.
