HYDATID CYSTS OF THE LIVER - 2 CAUTIONARY SIGNS

The purpose of this paper is to evaluate the significance of two CT fi ndings: evidence of an exophytic component of part of a hydatid cyst a nd dilated ducts in the vicinity of a cyst. The CT scans and clinical records of 63 patients were reviewed. There was evidence that cysts wi th an exophytic component are probably unstable and unsuitable for tre atment by percutaneous drainage or prolonged medical treatment. Dilate d pericystic ducts are a relative contraindication to nonsurgical trea tment because of the danger of complicating biliary obstruction. Surge ry should not be delayed unduly when either sign is encountered.
