Prevalence, Size and Location of the Accessory Spleen in Children
(Springer International Publishing, 2025) Ten, B.; Beger, O.; Cömert, A.D.; Beǧer, B.
Objective: The study was planned to evaluate the size, shape and prevalence of the accessory spleen (AS) in healthy children aged 1–18 years using their abdominopelvic computed tomography images. Methods: Pediatric subjects, who underwent abdominopelvic radiologic scan and admitted to the hospital between January 2011–December 2020 were included into the study for the detection of AS incidence. The antero-posterior, medio-lateral and supero-inferior diameters of AS and spleen were measured. In addition, the shape and localization of AS were noted. Results: The study population consisted of 3738 normal pediatric subjects (2320 males and 1418 females) aged 1–18 years. AS was found in 461 (12.3%) of this population. In addition, 92 (19.7%) out of 461 cases had more than one AS. Of the subjects with AS, 292 were male and 169 were female. The dispersion ratio of AS incidence in males and females proved that AS incidence did not correlate with sex (p = 0.291). Measurements in males were statistically similar to those in females, excepts from the supero-inferior diameter of the spleen (p = 0.036), which was greater in males than females. According to age groups, AS size did not change after early childhood period, but the size of the spleen increased up to postpubescent period. The most common location of AS was the middle third of the main spleen (23.9%). There were two different shapes of AS: 80% were round and 20% were ovoid. Conclusion: Approximately one in eight children has an AS, which is round and well-marginated mass. It reaches adult size in late childhood period (i.e., from the age of six). Approximately one in four ASs was located at the middle third of the spleen. © 2025 Elsevier B.V., All rights reserved.
Reference Values for Normal Main Portal Vein Diameter in Subjects Aged 1–80 Years
(Springer International Publishing, 2025) Binici, S.; Aslan, F.; Yanç, U.; Eryılmaz, I.; Tahiroǧlu, V.; Beǧer, B.; Uslu, N.
Purpose: Demographic features of subjects such as body mass index, height, weight, age or sex affect diameters of vessels like main portal vein (MPV). Some articles use different anatomical indicators like L1’s body for creating a complete standard while diagnosing venous pathologies. This work aimed to display relationships of portal veins with L1 in normal subjects aged 1–80 years. Methods: Abdominopelvic computed tomography views of 800 subjects were included in the work. The diameter of left (LPV) and right (RPV) branches of MPV, and the diameter of MPV at the distal level (MPV1), the middle level (MPV2), and the proximal level (MPV3) were measured. The transverse diameter of L1’s body (L1TD) was measured. The ratios of vein diameters to L1TD were calculated. Results: Age affected the diameters of portal veins and L1’s body. L1TD increased until the early 50 s, but thereafter showed no statistically significant change. The diameters of portal veins increased from birth to approximately the early 50 s, but then decreased statistically. Moreover, MPV1 / L1TD, MPV2 / L1TD and MPV3 / L1TD generally showed a pattern of first increasing and then decreasing with advancing age, whereas RPV / L1TD and LPV / L1TD showed a pattern of decreasing with advancing age. L1TD was greater in males than females (p < 0.001). MPV1, MPV2, MPV3, RPV and LPV were statistically similar for both sexes (p > 0.05). Conclusion: Age-specific diameter measurements and calculated ratios in our study may be useful for clinicians to diagnose disorders regarding portal system in pediatric and adult subjects. © 2025 Elsevier B.V., All rights reserved.
