Objective: To investigate the imaging characteristics and the cause for the misdiagnosis and mistreatment of epidermoid cyst in intrapancreatic accessory spleen (ECIPAS) in order to improve the accuracy of preoperative diagnosis. Methods: The clinical and imaging data of 8 patients with ECIPAS confirmed by pathology in Zhejiang Provincial People′s Hospital between June 2008 and February 2018 were collected. The reason for doctor visit included CA19-9 elevation (n=1) and pancreatic occupying mass (n=9) during physical examination and no obvious symptoms were reported. CT and MRI imaging features, diagnosis and treatment were analyzed. Results: The lesions in 8 cases of ECIPAS were all located in the tail of the pancreas and were cystic and solid. The lesions in 3 cases were mainly cystic and the cystic wall was linear, whose CT density, MRI signal and enhancement pattern cannot be compared with those of the spleen. Solid components can be seen in 5 cases, and the CT density or MR signal of the solid part was similar to that of the spleen. After enhancement, the solid part at the artery stage was uniformly enhanced and the enhancement degree was higher than that of the pancreas. Similar to the spleen, it was uniformly enhanced at the portal vein stage and the enhancement degree of the spleen was consistent. All 8 patients were diagnosed with pancreatic neoplastic lesions before surgery, and 1 patient had pancreatic fistula and peripancreatic necrosis after surgery. Postoperative pathology confirmed the diagnosis of ECIPAS. Conclusions Improving the radiologists and clinicians′ cognition of the imaging manifestations of ECIPAS can improve the accuracy of preoperative diagnosis and avoid unnecessary surgery due to misdiagnosis.

OBJECTIVES: Intrauterine adhesions (IUA) is the damage of the basal layer of the endometrium caused by various reasons, resulting in adhesion of the uterine muscle walls to each other, which is manifested as clinical symptoms such as spanomenorrhea, amenorrhea, and infertility. Hysteroscopic adhesiolysis (HA) is the main treatment, for patients with moderate or severe adhesion or angular adhesion, the incidence of postoperative adhesion is high. Traditional Chinese medicine "Yangmo decoction" can promote endometrial growth. Three-dimensional transvaginal ultrasonography (3D-TVUS) can judge IUA and evaluate uterine receptivity through three-dimensional imaging. This study aims to investigate the value of 3D-TVUS in judging the efficacy of Yangmo decoction in the treatment of intrauterine adhesions. METHODS: The clinical data of patients who underwent HA at two different centers in department of Gynecology of Third Xiangya Hospital of Central South University and Changsha Jiangwan Hospital from January 2021 to August 2021 were retrospectively collected. A total of 275 eligible patients were included. According to the postoperative management measures, the selected patients were divided into two groups. Yangmo decoction group (n=138): the use of Yangmo decoction and uterine-shaped silicon stent post HA; Hormone group (n=137): the use of estrogen, progesterone and uterine-shaped silicon stent post HA. The preoperative general data, preoperative and postoperative 3D-TVUS parameters of the two groups were analyzed. RESULTS: The endometrial thickness of Yangmo decoction group was thicker than that of hormone group (P<0.001), the intercornual distance was wider (P=0.016), the endometrial echo was more homogeneous (P=0.018), the percentage of bilaterally visible tubal opening was higher (P<0.001), the endometrial morphology was better (P=0.012), and endometrial blood flow, endometrial motility and uterine motion were better in Yangmo decoction group than that in the hormone group (all P<0.001). CONCLUSIONS The endometrial thickness, echo, blood flow, and peristalsis, the number of visible tubal opening, uterine motion, and the intercornual distance obtained by 3D-TVUS examination are important factors to evaluate the prognosis of postoperative drug treatment for IUA. 3D-TVUS is of great significance in evaluating the efficacy of Yangmo decoction in the treatment of IUA.
