Abstract
The aim of this study was to evaluate our experience with primary non-parasitic splenic cysts (NPSC) which are relatively rare in children and consist almost exclusively of single case reports or small case series in the literature. The medical records of all patients who presented to our clinic with NPSC between 2005 and 2015 were evaluated retrospectively. There were 22 children whose ages ranged from 2 months to 14 years (mean 9.2 ± 4.7 years). The size of the cysts was in the range of 5 to 200 mm (mean 55.4 ± 48.2 mm). Ten patients underwent surgery for splenic cysts. Partial splenectomy (n = 2), total cyst excision (either open n = 4 or laparoscopically n = 1), and total splenectomy (n = 3) were performed. The non-operated patients were asymptomatic and followed with ultrasound (US). The follow-up period in non-operated patients ranged from 6 months to 5 years (mean 2.27 ± 1.29 years). Complete regression was observed in four (33 %) non-operated patients. The regressed cyst measurements were 10, 16, 30, and 40 mm, respectively. Approximately half of the NPSC is diagnosed incidentally. Small (<5 cm) asymptomatic cysts should be under regular follow-up with US/physical examination for regression. If surgery is required, we prefer open cyst excision as it gives excellent results and preserves splenic immune function.
