ABSTRACT
A retrospective analysis was performed on 11 cases of Masson's tumor admitted to Liaocheng People's Hospital from January 2010 to July 2021. Among them, there were 4 males and 7 females, aged from 14 to 62 years, with a medical history of 1 to 24 months. All of the patients complained of touching the mass under the skin. In this group, 9 cases were pure form, 1 case was mixed form and 1 case was extravascular form. Ultrasound imaging can reflect the characteristics of Masson's tumor to a certain extent, which has a certain value in the diagnosis, classification and differential diagnosis.

AIM: To investigate the accuracy of ultrasonography in the diagnosis of persistent sciatic artery (PSA) compared to computed tomography angiography (CTA). MATERIALS AND METHODS: From May 2002 to Dec 2018, 61 consecutive patients seen at Shandong Medical Imaging Research Institute with a clinical suspicion of PSA were included. Ultrasonography was used to assess the abdominal and lower-limb arteries. The main sonographic criteria for a positive diagnosis were the visualisation of PSA, the enlarged internal iliac artery, and abnormality of common femoral artery and superficial femoral artery. These data were compared with CTA findings. Kappa statistics was applied to determine the level of agreement. The sensitivity, specificity, positive and negative predictive values, accuracy, and Youden index of ultrasonography as a diagnostic method were assessed. RESULTS: Ultrasonography findings were positive in 16 of 61 patients with a clinical suspicion of PSA. The diagnosis was confirmed by CTA in 17 patients. There was one false-positive result and two false-negative results at ultrasonography. The kappa value was 0.875. The sensitivity, specificity, positive and negative predictive values, accuracy, and Youden index of ultrasonography were 88.2%, 97.7%, 93.8%, 95.6%, 95.1% and 0.859, respectively. CONCLUSIONS: Ultrasonography could be a reliable, accurate, and non-invasive diagnostic imaging method in the diagnosis of patients with suspected PSA.

AIM: To evaluate the role of ultrasonography and magnetic resonance imaging (MRI) in the diagnosis of non-traumatic nerve fascicle torsion of the upper extremity. MATERIALS AND METHODS: Eleven patients (unilateral upper extremity) who underwent surgical treatment for nerve fascicle torsion were included in the study. Ultrasonography and MRI showed the detailed anatomy of the region well enough to reveal nerve fascicle torsion. The characterization and classification (single-segmental or multi-segmental) based on ultrasonography and diffusion-weighted (DW) MRI findings were recorded. RESULTS: The hourglass-shaped appearance was a characteristic feature of nerve fascicle torsion, Characterization and classification based on ultrasonography and MRI findings were consistent with intraoperative findings. CONCLUSION: Ultrasonography and MRI may be valuable in the diagnosis of non-traumatic nerve fascicle torsion of the upper extremity.
