多囊卵巢综合征

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

病史：女，31岁，迟于不法则。

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.

摄影机平庸：盆腔磁共振和MRI T2WI显示腺体增大，周边鞘泡大于12亚厘米。周边腺体组分在磁共振上强调谐，MRI上较差瞬时。鲜有优势卵泡。

DIAGNOSIS:

Polycystic ovary syndrome (PCOS)

病病病变：多鞘腺体综合征

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：多鞘腺体综合征也叫S-L综合征。是女持续性男婴的最相似原因。主要是由于肾上腺紊乱导致长期无排卵和甲状腺激素分泌物过丰。PCOS典型原于征：肥胖、闭经和小头病病变。但仅有将近病变平庸为此原于病病变。

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，需采用摄影机检查必要持续性获取越来越多信息。典型的磁共振/MRI腹水有数：腺体增大、变圆，外周多发布氏泡，腺体组分US上强调谐，T2WI较差瞬时。PCOS病变建议长期随访，因长期雌激素水平过高，才会全身性乳腺癌和子宫癌。
