Epidermal cysts of the clitoris are uncommon and usually associated with previous trauma. Surgical removal is the preferred treatment with close attention to preserve sensation and vascular supply. The use of an alternative coil during Magnetic Resonance (MR) imaging to visualize the anatomy may improve surgical management and outcomes.
A 15-year-old adolescent had a 2-year history of clitoral enlargement. Physical exam revealed a 4 × 5 cm clitoral cyst and normal hormonal evaluation. Initial MR with a pelvic coil showed poor resolution of neurovascular supply. MR was repeated using a small flex coil (commonly used on the wrist) placed as a sanitary napkin providing a higher resolution image of the neurovascular structures, which guided surgical intervention.
The use of the MR small flex coil to better visualize the external genital structures and clitoral anatomy improved preoperative evaluation and guided surgical management of the clitorial cyst.
阴蒂表皮样囊肿并不常见，通常与既往创伤有关。手术切除是首选治疗方法，需密切注意保留感觉和血供。在磁共振成像（MR）期间使用替代线圈来显示解剖结构可能会改善手术管理和结果。
一名15岁青少年有2年阴蒂增大病史。体格检查发现一个4×5厘米的阴蒂囊肿，激素评估正常。最初使用盆腔线圈进行的MR显示神经血管供应分辨率较差。使用一个小型柔性线圈（常用于手腕）重复进行MR检查，该线圈像卫生巾一样放置，提供了神经血管结构的高分辨率图像，从而指导了手术干预。
使用MR小型柔性线圈能更好地显示外生殖器结构和阴蒂解剖，改善了术前评估并指导了阴蒂囊肿的手术管理。
