We report a case of functional parathyroid cyst treated by ultrasound-guided anhydrous ethanol sclerotherapy and microwave ablation. The 63-year-old female patient was diagnosed to have functional parathyroid cyst with hypercalcemia, high PTH and cystic space-occupying lesions in the neck by ultrasound, radionuclide scanning and PTH measurement of the cystic fluid. The patient refused to receive cyst resection, and anhydrous ethanol sclerotherapy with microwave ablation was performed under ultrasound guidance. The procedure was completed smoothly without any complications either during or after the operation. Follow-up examination of the patient at 18 months after the operation showed a significant reduction of the mass and normal blood calcium and iPTH levels, demonstrating a clinical cure of the patient. Ablative treatment of functional parathyroid cyst has not been documented so far. This approach provides a minimally invasive treatment modality for such cases where surgical resection is not an option, but its efficacy and safety need to be evaluated in more cases with longer follow-up time.

OBJECTIVE: To assess the value of chromosomal microarray analysis (CMA) for the diagnosis of fetuses with anomalies of the central nervous system (CNS) and summarize the outcome of the pregnancies and follow-up. METHODS: A total of 636 fetuses from June 2014 to December 2020 who were referred to the Prenatal Diagnosis Center of Nanjing Drum Tower Hospital due to abnormal CNS prompted by ultrasound were selected as the research subjects. Based on the ultrasound findings, the fetuses were divided into ventricular dilatation group (n = 441), choroid plexus cyst group (n = 41), enlarged posterior fossa group (n = 42), holoprosencephaly group (n = 15), corpus callosum hypoplasia group (n = 22), and other anomaly group (n = 75). Meanwhile, they were also divided into isolated (n = 504) and non-isolated (n = 132) groups based on the presence of additional abnormalities. Prenatal samples (amniotic fluid/chorionic villi/umbilical cord blood) or abortus tissue were collected for the extraction of genomic DNA and CMA assay. Outcome of the pregnancies and postnatal follow-up were summarized and subjected to statistical analysis. RESULTS: In total 636 fetuses with CNS anomalies (including 89 abortus tissues) were included, and 547 cases were followed up. The overall detection rate of CMA was 11.48% (73/636). The detection rates for the holoprosencephaly group, ACC group, choroid plexus cyst group, enlarged posterior fossa group, ventricular dilatation group and other anomaly group were 80% (12/15), 31.82% (7/22), 19.51% (8/41), 14.29% (6/42), 7.48% (33/441) and 9.33% (7/75), respectively. Compared with the isolated CNS anomaly group, the detection rate for the non-isolated CNS anomaly group was significantly higher (6.35% vs. 31.06%) (32/504 vs. 41/132) (χ² = 62.867, P < 0.001). Follow up showed that, for 52 fetuses with abnormal CMA results, 51 couples have opted induced labor, whilst 1 was delivered at full term with normal growth and development. Of the 434 fetuses with normal CMA results, 377 were delivered at full term (6 had developmental delay), and 57 couples had opted induced labor. The rate of adverse pregnancy outcome for non-isolated CNS abnormal fetuses was significantly higher than that of isolated CNS abnormal fetuses (26.56% vs. 10.54%) (17/64 vs. 39/370) (χ² = 12.463, P < 0.001). CONCLUSION Fetuses with CNS anomaly should be tested with CMA to determine the genetic cause. Most fetuses with negative CMA result have a good prognosis, but there is still a possibility for a abnormal neurological phenotype. Fetuses with CNS abnormalities in conjunct with other structural abnormalities are at increased risk for adverse pregnancy outcomes.

OBJECTIVE: To study and analyze the diagnostic value and interventional treatment value of high-frequency ultrasound for elbow cyst. METHODS: From February 2018 to February 2021, the data of 60 patients with elbow cyst treated by high-frequency ultrasound interventional therapy were retrospectively analyzed, including 30 males and 30 females with an average age of (30.93±5.32) years old ranging from 20 to 54 years old. The course of disease ranged from 1 to 10 years with an average of (3.45±0.25) years. High-frequency ultrasound features of all patients were analyzed. The clinical efficacy, the occurrence of adverse events and the changes of psychological status before and after treatment were analyzed. RESULTS: In 60 cases of elbow cyst, the cyst size was from 6 mm×7 mm to 111 mm×60 mm. The characteristics of ultrasonic images included such as most of the morphology was regular, which was round or oval, and a few were irregular;the boundary was clear, there was a capsule wall, most of the inside of the capsule was good, no echo;when accompanied by bleeding or infection, small dense points can be seen floating;the cystic wall of the patients with long course of disease was coarser, and the internal light bands were separated, showing multilocular shape;no significant blood flow signal was observed. Final results involved olecranon bursa cysts in 19 cases, annular ligament cysts in 10 cases, radial bursa cysts in 9 cases, accessory ligament cysts in 7 cases, epidermoid cysts in 4 cases, ganglion cysts in 6 cases, nerve sheath cysts in 5 cases. After treatment, 33 cases were cured, 16 cases had obvious effect, 11 cases were improved, 0 cases were invalid. After treatment, mild adverse events occurred in 1 case, moderate adverse events in 1 case, and severe adverse events in 0 cases, with a total incidence of 3.33% (2/60). After treatment, positive affect score (38.04±1.74) was higher than that before treatment (35.92±2.34), and negative affect score (24.61±1.51) was lower than that before treatment (30.15±3.46), with statistical significance(P<0.05). CONCLUSION High-frequency ultrasound has high diagnostic value for elbow cyst, and it has ideal effect in interventional therapy.

Ultrasound guided percutaneous interventional therapy has been widely used in clinic. Aiming at the problem of soft tissue deformation caused by probe contact force in robot-assisted ultrasound-guided therapy, a real-time non-reference ultrasound image evaluation method considering soft tissue deformation is proposed. On the basis of ultrasound image brightness and sharpness, a multi-dimensional ultrasound image evaluation index was designed, which incorporated the aggregation characteristics of the organization. In order to verify the effectiveness of the proposed method, ultrasound images of four different models were collected for experiments, including prostate phantom, phantom with cyst, pig liver tissue, and pig liver tissue with cyst. In addition, the correlation between subjective and objective evaluations was analyzed based on Spearman's rank correlation coefficient. Experimental results showed that the average evaluation time of a single image was 68.8 milliseconds. The evaluation time could satisfy real-time applications. The proposed method realizes the effective evaluation of real-time ultrasound image quality in robot-assisted therapy, and has good consistency with the evaluation of supervisors.

OBJECTIVE: To analyze clinical and genetic features of a family affected with Van der Woude syndrome. METHODS: The umbilical cord blood of the proband and the peripheral blood of the parents were used for the whole exon sequencing to find the candidate gene.Peripheral blood of 9 members of the family were collected for Sanger sequencing verification, bioinformatics analysis and genotype-phenotype correlation analysis. RESULTS: The proband was diagnosed with cleft lip and palate by ultrasound. His father and grandmother had hollow lower lip and all other family members did not have the similar phenotype. A missense c.263A>G (p.N88S) mutation was found in exon 4 of gene in the proband, his father and his grandmother.The mutation was not found in other family members. CONCLUSIONS A missense c.263A>G (p.N88S) mutation in gene probably underlies the pathogenesis of Van der Woude syndrome in the family and the mutation has been firstly discovered in China.

PURPOSE: The purpose of this study was to investigate the feasibility of shear wave ultrasound elastography for differentiating superficial benign soft tissue masses through a comparison of their shear moduli. METHODS: We retrospectively analyzed 48 masses from 46 patients from February 2014 to May 2016. Surgical excision, fine-needle aspiration, and clinical findings were used for the differential diagnosis. The ultrasonographic examinations were conducted by a single musculoskeletal radiologist, and the ultrasonographic findings were reviewed by two other radiologists who were blinded to the final diagnosis. Conventional ultrasonographic features and the median shear modulus were evaluated. We compared the median shear moduli of epidermoid cysts, ganglion cysts, and lipomatous tumors using the Kruskal-Wallis test. Additionally, the Mann-Whitney U test was used to compare two distinct groups. RESULTS: Significant differences were found in the median shear moduli of epidermoid cysts, ganglion cysts, and lipomatous tumors (23.7, 5.8, and 9.2 kPa, respectively; P=0.019). Epidermoid cysts showed a greater median shear modulus than ganglion cysts (P=0.014) and lipomatous tumors (P=0.049). CONCLUSION: Shear wave elastography may contribute to the differential diagnosis of superficial benign soft tissue masses through a direct quantitative analysis.

Carpal tunnel syndrome can be produced by abnormal mass effect due to trauma, ganglion cysts, various soft tissue tumors, musculotendinous variants, and aberrant vascular structures. Persistent median artery is one of the causes of the carpal tunnel syndrome. Thrombosed persistent median artery usually accompanies the anomaly of the median nerve and causes a sudden onset of severe pain and paresthesia. In contrast to previous literature, we report the rare case of gradual onset and mild symptom of a 53-year-old man with a thrombosed persistent median artery but without anomaly of the median nerve and abnormal finding of electrophysiologic study.

ObjectiveTo investigate the diagnosis and treatment of ejaculatory duct cyst.

METHODSThis study included 2 male patients present at the hospital for hemospermia and abnormal sensation in the perineal region in July and August 2014. Both underwent transrectal ultrasonography, routine semen examination, CT, MRI, cystoscopy, and vesiculography before transurethral fenestration of the cysts and pathological examination of the cyst wall specimens. Analyses were made on the clinical presentations, imaging features, pathological characteristics, differential diagnosis and treatment of ejaculatory duct cyst and relevant literature was reviewed.

RESULTSThe cyst wall was mainly composed of smooth muscle, the inner wall lined with pseudostratified ciliated columnar epithelia, and with positive expressions of CD10 and Muc6 proteins on immunohistochemical staining, which indicated renal iatrogenic ejaculatory duct cyst. The patients were followed up for 18 and 20 months, respectively. All symptoms disappeared and no recurrence occurred after surgery. Routine semen examination for the two patients showed the semen volumes to be 3.5 and 3.1 ml, sperm concentrations 35 and 32 ×10⁶/ml, grade a sperm 32.0 and 26.0%, grade b sperm 18.0 and 31.0%, and semen liquidation time 30 and 34 minutes, respectively.

CONCLUSIONSPelvic cystic masses can be detected by transrectal ultrasonography, CT and MRI, but definite diagnosis relies on vesiculography, pathological examination and immunohistochemical staining. Transurethral fenestration is safe and effective for the treatment of ejaculation duct cyst.

OBJECTIVE: To evaluate the effect of tamoxifen on female reproductive organs in women with breast cancer. METHODS: We retrospectively reviewed the medical records of 309 women with breast cancer who were currently receiving tamoxifen and undergoing regular gynecological examination. RESULTS: We evaluated 92 pre- and 217 postmenopausal women. The prevalence of endometrial thickening was 12% in the pre- and 10.6% in the postmenopausal group. An endometrial biopsy was performed in 43 women and confirmed endometrial cancer in 1, endometrial polyps in 14, and endometrial hyperplasia in 4 women. Transvaginal ultrasonography showed 25 cases of newly developed ovarian cysts. Most ovarian cysts had disappeared during follow-up. CONCLUSION: Tamoxifen use in women with breast cancer causes few complications and is considered safe for female reproductive organs in case of regular gynecological examination.
