title: [Simple testicular cyst].
abstract: High-resolution sonograms of scrotum in two hundred and ninety six patients were reviewed. Twenty six patients were found to have simple testicular cyst(s). The specific features of cyst, which included sharp clear margin, anechoic content, posterior wall enhancement and no adjacent echogenic mass, could be found in all lesions. Four cases had bilateral testicular involvement. Solitary cystic lesion was found in 14 tests. The size ranged from 2.0 mm to 1.2 cm. Clustered cystic lesions were found in six testes. The size ranged from 4.0 mm to 2.5 cm. More than one focal lesion were found in 10 testes. Twenty four of these thirty testes had tunica albuginea cyst(s) or cyst(s) abutting on testicular margins. Four patients had follow-up sonograms with the period ranging from three months to two years. No remarkable change of all lesions were noted. The sonographic pictures and its patterns were presented. The pathogenesis and the literature were briefly reviewed.
