Chondrosarcomas of the larynx are rare cancers, representing less than 1% of all laryngeal tumors. The most often involved site is the cricoid cartilage. They have generally good prognosis, and low metastatic tendency. Surgery is the treatment of choice, partial in small limited tumors or total laryngectomy if tumor extends beyond the half of the cricoid and/or is poor differentiated. Although there are some pathognomonic imaging characteristics for chondrosarcomas, the histology remains the gold standard for diagnostic. The authors present a case of large, medium differentiated chondrosarcoma (grade II), surgically treated by total laryngectomy.

Objectives The aim of this study was to determine whether preoperative ultrasound imaging characteristic(s) in cats suffering from unilateral benign ureteral obstructions are predictive of outcome after successful renal decompression with a subcutaneous ureteral bypass (SUB) device. Methods This was a retrospective study of 37 cats with unilateral, benign ureteral obstruction. Preoperative imaging characteristics (including renal pelvis diameter, parenchymal thickness [transverse plane], renal length and pelvic size:overall renal size) and biochemical data were evaluated for all cats diagnosed with a unilateral ureteral obstruction treated with a SUB device. Any patient with bilateral obstructions or documented bacteriuria/infection in the data collection period was excluded. All patients were followed between 3 and 6 months postoperatively to obtain postoperative biochemical data. Long-term outcome was defined as serum creatinine concentration at 3–6 months postoperatively. Results No preoperative imaging characteristics or biochemical findings were found to be significantly associated with long-term serum creatinine concentrations. The length of the kidney was found to be associated with change in blood urea nitrogen and creatinine with decompression but not with long-term renal values. Conclusions and relevance In this study, long-term renal function based on preoperative ultrasound imaging findings could not be predicted in cats with unilateral ureteral obstruction, regardless of the severity of the biochemical parameters, renal pelvic dilation (large or small pelvis), kidney size or thickness of renal parenchyma assessed.

Acute Pelvic Inflammatory Disease

Common types of gynecological acute abdomen include ovarian cyst pedicle torsion, ectopic pregnancy, luteal rupture, and acute pelvic inflammatory disease. Make accurate diagnosis and surgical treatment of acute abdomen patients in obstetrics and gynecology in time, otherwise it will cause life danger or loss of organ function, therefore, accurate and timely diagnosis and treatment of gynecological acute abdomen is very important for the prognosis of patients. Ultrasound imaging has important clinical value for the diagnosis of acute abdomen in obstetrics and gynecology. Ultrasound imaging has the advantages of simple examination, rapid reporting, and no pain in the subject, which is one of the best methods for diagnosing acute abdomen in obstetrics and gynecology. This study analysed and summarized the imaging principles of ultrasound imaging in acute obstetrics and gynecology and the imaging characteristics of various acute abdomen. A retrospective analysis of patients with acute obstetrics and gynaecology performed in our hospital from December 2017 to June 2019 was performed. The diagnostic analysis of ultrasound imaging in acute obstetrics and gynaecology was performed. The results showed that the ultrasound imaging diagnosis results of 202 obstetric and gynecological acute abdomen patients were compared with the results of surgery and pathological diagnosis. Among the 182 cases with correct ultrasound imaging diagnosis, the coincidence rate was 90.1%, and 20 cases were misdiagnosed, accounting for 9.9%. The research of this study shows that the ultrasound examination technique for patients with acute obstetrics and gynaecology is simple, fast, non-invasive, and has high accuracy. Ultrasound imaging can provide reliable objective evidence for the diagnosis and differential diagnosis of most acute abdominal diseases, in order to improve the diagnosis rate and reduce the misdiagnosis rate.

Abstract Purpose To determine the ultrasound imaging characteristics of participants with bronchial anthracofibrosis (BAF) and identify clinical markers for prevention and treatment. Methods We randomly selected 1,243 participants (including 113 with BAF) who underwent bronchoscopy and treatment at our institution from April 2018 to October 2019. BAF was classified as flat, deep seated retracted, or mucosal protrusion type, based on microscopy. Ultrasound probes were used to determine the maximum thickness of the tube wall and submucosa. The average values of the submucosal and bony tissue areas of the BAF subtypes were compared. Results The BAF group included 13 participants with a history of tuberculosis (11.5%) and 57 with biofuel exposure (50.4%). The average exposure time was 17.4 ± 6.2 years; BAF accounted for 10% of bronchoscopies performed. The maximum tube-wall thicknesses of the deep-seated retracted (17.3 ± 5.7) and black protruding (19.3 ± 5.4) groups were significantly greater than that of the flat group (12.5 ± 5.0; P < 0.05). The maximum thicknesses of the submucosa in the deep-retracted (9.8 ± 3.0) and black protruding (14.5 ± 5.0) groups were significantly greater than that of the flat group (6.6 ± 3.5; P < 0.05). The ratios of bone tissue in the flat and black protruding groups were 33.3 ± 9.3% and 34.9 ± 12.1%, respectively; the ratio in the deep-seated retracted group (65.2 ± 8.7%) was significantly reduced (P < 0.05). The flat type showed no significant change (P > 0.05). Conclusion Differences in BAF airway remodeling among the different subtypes may lead to varying clinical symptoms. Analyzing the characteristics of BAF airway remodeling and the regulatory pathway may provide new clues for treatment.

Background. Patients with cholangiocarcinoma (CCA) have poor prognosis and high mortality. Therefore, early detection and early diagnosis are extremely important to control the development of CCA. This study aims to explore the diagnostic effect in patients with CCA and imaging characteristics of MRI combined with CT. Methods. 109 patients with suspected CCA underwent CT and MRI before diagnosis. The examination results were compared with the “gold standard.” ROC curve was drawn to analyze the diagnostic efficacy of MRI combined with CT for CCA patients. Results. The diagnosis rate of suspected CCA patients was 95.41%. The diagnostic coincidence rate of CT and MRI examination was 89.42% and 92.31%, respectively. The diagnostic coincidence rate of MRI combined with CT examination was 100.00%. The number of CT delayed enhancement, peripheral bile duct dilatation, and hepatic capsular depression were more than those of MRI. The number of circular enhancement cases in the CT group was less than that in the MRI group. ROC curve results showed that the sensitivity and specificity of MRI combined with CT for the diagnosis of CCA patients were higher than those of MRI or CT alone. Conclusion. MRI combined with CT has high diagnostic sensitivity and specificity and can provide imaging evidence for the clinical diagnosis and treatment of CCA.
