Percutaneous treatment of an orbital hydatid cyst: a new therapeutic approach
1Department of Radiology, Hacettepe University School of Medicine, Sihhiye, Ankara, Turkey.
Purpose:
To describe the percutaneous treatment of an orbital hydatid cyst as an alternative approach to conventional surgery.
Methods:
In a 21-year-old man with diplopia and right proptosis, radiologic studies disclosed a 25 x 25 x 20-mm purely cystic mass in the right retrobulbar area. Based on the presumptive diagnosis of hydatid cyst, the cyst was treated percutaneously under ultrasonographic guidance with aspiration, 15% hypertonic saline injection, and reaspiration without any complication.
Results:
A substantial decrease in the size of the cyst was observed in the 3 months after treatment. Nine months after treatment, the shrunken cyst had a volume of only 0.5 ml, and the patient was asymptomatic. Twenty-one months after the procedure, the findings were consistent with those at 9 months of follow-up.
Conclusion:
Percutaneous treatment of orbital hydatid cysts, which is more satisfactory to both the patient and the physician, may be a safe and effective alternative to surgical extirpation.
