Epidermoid cysts are rare tumours, which account for 1% of all testicular tumours. Very rarely, they are intrascrotal but extratesticular. We present a rare case of an intrascrotal extratesticular cyst. The triad of findings were sonographic appearance of an onion ring, avascularity on Doppler sonography and negative results of tumour markers; these are highly suggestive of an epidermoid cyst.
表皮样囊肿是一种罕见的肿瘤，占所有睾丸肿瘤的 1%。它们非常罕见地位于鞘膜内但位于睾丸外。我们报告了一例罕见的鞘膜内睾丸外囊肿病例。超声表现为洋葱环样外观、多普勒超声显示无血管性和肿瘤标志物检测结果阴性，这三点高度提示为表皮样囊肿。
