Hydatid Cyst With Various Organ and Tissue Involvement: A Single-Center Data

INTRODUCTION: Hydatid cyst (CH) is a zoonotic infection caused by the parasite Echinococcus Granulosus. This study aims to determine the prevalence of hydatid disease presenting to our center and to present and discuss rare localized CH samples.
METHODS: A total of 1247 patients were evaluated in the study. All patients were noted as Type 1 through Type 5. In addition, cysts not included in the Gharbi classification and diagnosed with Echinococcus alveolaris were defined as Type 6, infected CH as Type 7, post-operative (PAIR and/or surgery) CH as Type 8, and ruptured CH as Type 9, for ease of lesion identification and classification.
RESULTS: A total of 936 patients were included in the study. The average hydatid cyst lesion size is 6.6±3.7 (min=0.6-max=47) cm. When the hydatid cyst lesions of the patients were examined, it was seen that 90.9% had one stage (type), 7.8% had two stages, and 1.3% had three stages. 28.5% of the patients had Type 1, 12.7% had Type 2, 12% had Type 3, 16.9% had Type 4, 22.8% had Type 5, 2.5% had Type 5. It was observed that 0.5% was Type 6, 0.5% was Type 7, 4.8% was Type 8, and 9.5% was Type 9.
DISCUSSION AND CONCLUSION: Since the condition or stage of the lesion is important in the treatment and follow-up of hydatid cysts, it would be logical and guiding to classify it as in our study.
