Objective:To summarize the ultrasound characteristics of incarceration of gravid uterus (IGU) for improving the diagnostic accuracy of IGU.Methods:Three cases of IGU patients were diagnosed in Peking University Third Hospital from May 2018 to May 2020. CNKI, Wanfang Data, China Science and Technology Journal Database and PubMed were searched using the search terms "incarcerate uterus" or "uterine incarceration" and "gravid" through January 2000 to July 2020, 53 IGU cases were found. The ultrasound data and outcomes of the 56 IGU patients were retrospectively analyzed. The display rate of various ultrasonic features were counted. Relevant literatures were reviewed and the experience were summarized.Results:Of the 56 cases with IGU, 45 cases (80.4%) had positive results, of which 34 cases (60.7%) were found abnormal cervix(elongated anteriorly and superiorly displaced cervix or poorly visualized cervix), 27 cases (48.2%) were found retroversion of the gravid uterus, 12 cases (21.4%) were found that the fundus of the uterus lay deeply in the Douglas pouch, 4 cases (7.1%) were found anteriorly and superiorly displaced bladder. There was statistically significant difference between the displaying rates of abnormal cervix and retroversion of the gravid uterus(χ 2=5.452, P<0.05). Conclusions:Abnormal cervix was the most common feature of IGU by ultrasound. Correct identification of the cervix is helpful to improve the detection rate of IGU.

Objective To study the clinicopathological and immunohistochemical features, histogenesis and biological behavior of solid pseudopapillary tumor of the pancreas ( SPT ). Methods Routine HE and immunohistochemical ( SP) methods were used in 20 cases of SPT. Results There were 18 females and 2 males, age ranging from 13 to 48 years with mean age of 25. 3 years. Abdominal pain and palpable mass were among the main complains. Seventeen cases were followed-up from 9 to 120 monthes. Fourteen cases were alive. Tumors were encapsulated, mixed with solid and cystic tissues. Histological features were psudopapillary structure with a fibrovascular core. Immunohistogically, the tumors were positive for a-1-AT ( 17 cases) , vimentin ( 14 cases) , synaptophysin ( 10 cases) , CgA (5 cases) ,CK and insulin (2 cases) ,glucagon and S-100 (1 case) ,PR (14 cases) , ER (1 case) ,pS2 (6 cases) , but all were negative for CEA and gastrin. Conclusion SPT is of low-graded malignancy and a distinct clinicopathologic entity in young female patients with both exocrine as well as endocrine differentiation. The tumor is closely related with sex hormone receptors.

Objective To explore the clinical significance of abnormal fetal genitalia detected by routine prenatal ultrasound. Methods In Peking University Third Hospital from January 2014 to January 2016, the ultrasonic diagnosis and sonographic features in 14 suspected cases of abnormal fetal genitalia were analyzed retrospectively and compared with postpartum morphological and pathological characteristics. Results The fetal ultrasound findings and clinical outcomes in 14 cases were: (1) There were 4 cases of partial penoscrotal transposition (28.6%, 4/14), in which all fetus hadshort penis and hypospadias. In 2 termination cases, unilateral hydronephrosis and anal atresia was found in one case, while ventricular septal defect was found in the other case. In 2 term-birth cases, there was one case of recessive spina bifida. In the 4 cases, prenatal ultrasonographic manifestation showed that the short penis was located between the division of the scrotum, named as ″tulip sign″. (2) There were 2 cases (14.3%, 2/14) of complete penoscrotal transposition, in which all the pregnancies were terminated. On prenatal ultrasound of external genitalia, the location of the penis and scrotum was reversed. In one case, anal atresia and small eye malformation were found. In one case, the tetralogy of Fallot, duodenal atresia and anal atresia were found. (3) There were 4 cases of the micropenis (28.6%, 4/14). On prenatal ultrasound, the penis was difficult to demonstrated and was shown merely as an echoic dot. Among 2 cases of FGR, one infant dies for unexplained reasons after birth, and one infant has hypospadias after birth. The pregnancy was terminated in two cases of 18-trisomia and microdeletion in chromosome 9. (4) There were 2 cases of penis absence (14.3%, 2/14), in which all pregnancies were terminated. The sonographic manifestations show the absence of penis and bladder eversion. (5) In 2 cases, sex couldn`t be identified (14.3%, 2/14). In one case, the 46 xy infant showed a female external genitalia appearance after birth. In one case, the clitorism and congenital adrenal cortical hyperplasia were found in a 46 xx infant after birth. Conclusions Prenatal ultrasonography is effective and feasible in detecting genitalia abnormalities, especially for penis scrotal transposition and penis absence. When the fetal gender cannot be identified on ultrasound, chromosome examination is warranted. For indeterminable cases, ultrasound follow-up in 2nd and 3rd trimester is necessary.
