Summary
Introduction: Renal echinococcosis is a rare disease that is asymptomatic in most cases and can be difficult to detect. Reviewing the literature, renal echinococcosis is usually associated with liver and lung involvement, isolated cases only occurs in 2% of the affected patients. In our case study, we present a case of a patient with an accidentally discovered renal echinococcosis.
Case report: In January 2020, a 40-year-old male was diagnosed with prostate cancer. During the staging examination, an 8 cm lesion was discovered by a CT scan on the lower pole of the left kidney. Our patient underwent laparoscopic radical prostatectomy in early February 2020. During the postoperative period, thin needle aspiration cytology (FNAB) examination was performed from the above-mentioned lesion confirming a haemorrhagic cyst. A follow-up CT scan was performed, showing an increase in size. Subsequently, we requested an FNAB test once again, which revealed an atypical cyst, but the possibility of a cystic kidney tumour also arose. Due to the progression and CT image and the central location of the tumour, we decided to perform a radical nephrectomy. The final histological examination evaluated a renal echinococcus cyst. Postoperative control of abdominal ultrasound and chest CT echinococcosis in other organs has not been established.
Conclusion: Echinococcosis is a rare, but more harmful, parasitic disease in humans. Symptoms appear to play an important role in imaging studies. Early surgical intervention is recommended when the lesion is recognized.
