Introduction: Acute scrotum is a common surgical condition. Ultrasound along with Doppler plays an important role in differentiating the various causes. Purpose of this study was to evaluate the role of ultrasound in identifying the various causes of acute scrotum.Methods: All patients with history of acute scrotum presenting to the Department of Radiology were included in the study. Scrotal ultrasound was performed with a linear 7.5 to 12-MHz transducer with abundant acoustic gel. Imaging was done in longitudinal and transverse planes with Power Doppler and Color Doppler. The testes, epididymis, spermatic cord, scrotal wall and inguinal region were evaluated. Kidney, Ureter and Bladder region was evaluated for possibility of calculus. Final diagnosis was made based on clinical outcome, follow up, intraoperative findings and histopathology when available. Statistical analysis was done using SPSS version 18 for windows. Descriptive analysis was done. Non parametric correlation between side and torsion was done using Kendall Rank Correlation Coefficient.Results: There were altogether 50 patients available for statistical analysis. Age of the patients ranged from 14 to 65 years with mean age of 34.7±14.7 years. Most common age group was 21 to 40 years. Inflammatory pathology was the most common pathology of actual scrotal pain. There was no significant correlation between side of pain and testicular torsion.Conclusion: Inflammatory pathology was the most common cause for actual scrotal pain. The most common age group was 21 to 40 years.

The authors report a case of a middle-age man presenting with a category IV pressure ulcer (PU) over the sacrum. Undermining of the PU was assessed with the aid of gray-scale sonography (US), color Doppler US, power Doppler US, and a microvascular imaging technique employing advanced clutter suppression. Clutter suppression post-processing the study allowed for the evaluation of low-velocity microvascular flow in the undermined PU and facilitated the choice of appropriate treatment.

In this case we aimed to present use of superb microvascular imaging (SMI) in the discrimination of fetal intracranial mass- haemorrhage with the light of literature. 21 weeks pregnancy woman applied to the clinic for routine obstetrics control. Ultrasonography (US) was applied to the patient. In the gray scale US, intracranial midline a large mass was detected. In the colour doppler (CD), the blood flow (BF) to the mass was not clearly seem. Power doppler (PD) was very artifact. In color SMI (cSMI) and monochrome SMI (mSMI), blood flow (BF) of the mass was seem clearly and fetal intracranial mass was prediagnosed. Magnetic Resonance imaging (MRI) was performed to determine the location of the mass, brain parenchyma and origin of the mass. Intracranial midline a large mass was detected in fetal MRI too. Although there are cases in the literature regarding the use of SMI in obstetrics, there is no case report in which fetal intracranial mass was evaluated by SMI to our knowledge. In our case; we have detected fetal intracranial mass by gray scale US, and we have evaluated vascularization of the mass by CD, PD, cSMI and mSMI. SMI modes were showing superiority when compared to CD and PD. Vascularization could be seen more clearly by mSMI when compared to cSMI.

A 60-year-old woman with rheumatoid arthritis consulted for acute flare. She had elevated disease activity score 28 - erythrocyte sedimentation rate (DAS 28-ESR) of 6.88 and clinical disease activity index (CDAI) of 32. Her 12-joint ultrasound revealed widespread joint effusion. Synovial vascularity scores measured through superb microvascular imaging (SMI) and power Doppler were universally increased. We documented her treatment response 2 weeks after she received a single dose of biosimilar infliximab using clinical and sonographic data. Her DAS 28-ESR and CDAI scores decreased to 4.21 and 7.0, respectively. Reduction in synovial vascularity scores was demonstrated using SMI. While there was near total resolution in joint effusion and tenosynovitis, SMI was able to demonstrate synovial vascularity in joints with no clinical swelling nor tenderness. Musculoskeletal ultrasound and superb microvascular imaging are useful adjuncts in evaluating synovitis in rheumatoid arthritis and documenting treatment response through documentation of synovial vascularity, effusion and tenosynovitis.
