A seminal vesicle cyst is a rare etiology of pelvic pain. However, its rarity may result in oversight or misinterpretation if the radiologist or emergency physician is unfamiliar with this entity. Seminal vesicle cysts may cause pelvic pain because of mass effect, infection, internal hemorrhage, or urinary and bladder obstruction. Because seminal vesicle cysts rarely result in physical examination findings or laboratory abnormalities, pelvic computed tomography plays a pivotal role in their diagnosis and in evaluating patients with pelvic pain. Recognition of the imaging findings of seminal vesicle cysts is necessary to allow prompt, accurate diagnosis. Therefore, emergency physicians and radiologists interpreting examinations from the emergency department should be familiar with these imaging findings because seminal vesicle cysts may be the etiology of pelvic pain and the patient may benefit from urologic consultation and cyst aspiration or resection. The purposes of this article are to provide examples of pelvic pain caused by seminal vesicle cysts, illustrate the key imaging findings on computed tomography, and briefly review the literature.
精囊囊肿是引起盆腔疼痛的罕见病因。然而，如果放射科医生或急诊医生不熟悉这种病变，其罕见性可能导致漏诊或误诊。精囊囊肿可因占位效应、感染、内出血或尿路及膀胱梗阻引起盆腔疼痛。由于精囊囊肿很少引起体格检查或实验室异常，盆腔 CT 在其诊断和评估盆腔疼痛患者中起着关键作用。识别精囊囊肿的影像学表现对于及时、准确诊断至关重要。因此，解读急诊科检查的急诊医生和放射科医生应熟悉这些影像学表现，因为精囊囊肿可能是盆腔疼痛的病因，患者可能受益于泌尿科咨询和囊肿抽吸或切除术。本文旨在提供精囊囊肿引起盆腔疼痛的病例示例，说明 CT 上的关键影像学表现，并简要复习相关文献。
