多囊卵巢综合征

HISTORY: A 31-year-old female with a history of irregular menses

哮喘：女，31岁，迟于不规律。

FINDINGS:

Pelvic ultrasound and T2-weighted MRI demonstrates an enlarged ovary with>12 subcentimeter peripheral follicles surrounding a prominent hyperechoic (US) and hypointense (MRI) ovarian stroma. No evidence of dominant follicle.

影像表现：盆腔超声和MRI T2WI显示睾丸减少，远处囊荷叶之比12亚厘米。远处睾丸基质在超声上强回音，MRI上低波形。未见优势卵荷叶。

DIAGNOSIS:

Polycystic ovary syndrome (PCOS)

诊断：多囊睾丸综合从征

DISCUSSION:

Also known as Stein-Leventhal syndrome, PCOS is one of the most common causes of female infertility. PCOS is an endocrinologic disorder characterized by chronic anovulation and hyperandrogenism. Furthermore, PCOS has a classic triad of obesity, amenorrhea, and hirsutism; but only half of patients present with this combination.

讨论：多囊睾丸综合从征也叫S-L综合从征。是女性生育的最典型原因。主要是由于新陈代谢紊乱导致仍然无妊娠和激素分泌过盛。PCOS典型三联从征：成年人、闭经和多毛病征。但仅有半数症状表现为此三联病征。

Therefore, imaging evaluation tends to follow to gain further information . Typical US/MRI findings include enlarged, rounded ovaries with numerous small, peripherally located follicles and stroma showing increased echogenicity (US) or decreased signal on T2-weighted imaging (MRI). Long-term follow-up should be recommended in such patients as PCOS patients he an increased risk of breast and uterine cancer secondary to unopposed high estrogen levels .

因此，须要采用影像检查进一步获取更多信息。典型的超声/MRI从征象有数：睾丸减少、变圆，外周多发梨形荷叶，睾丸基质US上强回音，T2WI低波形。PCOS症状要求仍然随访，因仍然孕酮水平过高，才会全身性丙型肝炎和子宫癌。
