Objective: We aimed to evaluate ovarian vascularity with superb microvascular imaging (SMI) and to compare it with other conventional Doppler imaging methods in girls with premature thelarche, precocious puberty, and those at puberty. Methods: A total of 133 ovaries from 69 patients were evaluated. Among the 69 subjects, 50 girls applied with the preliminary diagnosis of precocious puberty, and 19 of them were pubertal adolescent girls. The color Doppler imaging (CDI), power Doppler imaging (PDI), color SMI (cSMI), and monochrome SMI (mSMI) techniques were performed, and the images at the same site of the ovary were obtained. The images were evaluated by 2 pediatric radiologists using a 4-level grading system to evaluate the degree of vascularity. Results: A total of 69 patients were evaluated, including 19 who were pubertal, 39 with premature thelarche (PT), and 11 with precocious puberty (PP) were evaluated. Among the 50 patients, 11 were diagnosed with precocious puberty, while 39 received a diagnosis of premature thelarce. The sensitivity of the techniques according to vascularity grading was interpreted as mSMI > cSMI > PDI > CDI. The interrater agreement of vascularity grading among the two observers according to their κ values was almost perfect in the left CDI, left PDI, and right PDI (κ > 0.92), strong in the right CDI, left and right cSMI, left and right mSMI (κ > 0.80), and moderate in the right CDI (κ > 0.60). There was a significant difference between the vascularity of pubertal and prepubertal ovaries, which correlated with their volumes (P < .001). Ovarian vascularity was similar in precocious puberty and premature thelarche groups. Conclusion: The SMI is superior to other Doppler methods, such as PDI and CDI, in the evaluation of ovarian vascularity. It is useful in evaluating parenchymal vascularity, especially in pediatric patients. [ABSTRACT FROM AUTHOR]

Burkitt lymphoma is an aggressive and rapidly growing tumor that is curable and highly sensitive to chemotherapy. It can affect almost every tissue in the body, producing various clinical presentations and imaging appearances, according to the predilection of the different subtypes for certain sites. Awareness of its diagnostically specific imaging appearances plays an important role in rapid detection and treatment. In this pictorial review, we aimed to identify the most common imaging features of Burkitt lymphoma in pediatric patients. [ABSTRACT FROM AUTHOR]

Background/aim: Our aim was to interpret the effects of deep neck space abscesses on the adjacent carotid artery according to abscess location, as well as to determine narrowing by calculating the mean stenosis ratios.Materials and methods: Neck computed tomography scans and clinical data of 45 children with neck abscesses were evaluated retrospectively for abscess location and internal carotid artery narrowing. The lumen areas of the carotid arteries were measured from standard levels, and stenosis ratios were calculated with two different techniques. The mean stenosis ratios of each group according to abscess location were then compared with the control group.Results: Among the 45 abscesses included in the study, 51.1% (n = 23/45) were located in the peritonsillar region, 37.8% (n = 17/45) were located in the parapharyngeal-lateral retropharyngeal space, and 11.1% (n = 5/45) were in the midline retropharyngeal space. We found a statistically significant difference between the mean stenosis ratios of the ipsilateral side of the parapharyngeal-lateral retropharyngeal abscesses and the control group (P < 0.01).Conclusion: The children with parapharyngeal-lateral retropharyngeal abscesses all had narrowing in the adjacent carotid lumen to some degree. Although most of the patients had no clinical symptoms, radiologists have to be aware of this arterial complication to prevent further progress and fatal complications.
