Abstract：Objective To explore the characteristics and misdiagnosis causes of ultrasound in diagnosis of cystic renal cell carcinomas ( CRCC) . Methods Clinical and ultrasonic features in 17 patients with CRCC confirmed by operative pathol-ogy were retrospectively analyzed. Results The ultrasound examination results showed that the tumor diameter was ranged from 1. 7 cm to 16. 0 cm and averaged (8. 2 ± 0. 5) cm in the 17 patients. There were 10 patients with multicystic lesion, 6 patients with single cystic lesion, and one patient with single cystic lesion in left kidney and polycystic lesion in right kidney. A total of 13 patients were diagnosed as having CRCC, and 4 patients (23. 53%) were misdiagnosed as having renal cyst. A-mong the 4 patients, 3 had large CRCC, in whose ultrasound results showed regular and thin cyst wall and no nodular lesions, low echo of capsular space, and no clear blood flow echo in both cyst wall and capsular space. For one patient with multicystic lesions, the ultrasound results showed that cyst septum and wall were regular and thin, except the junction of the septum and wall;no blood signal was found. Conclusion Ultrasonography can provide important evidences for early diagnosis of CRCC.
