Patient and Data
The Ethics Committee of the Jikei University School of Medicine approved
the case report with written informed consent from our patient. In the
review of the case series, we searched for case reports of SCL between
1979 and 2022 in the Japan Medical Abstracts Society, a database of
Japanese medical literature. We collected data including age, sex, the
period from perception of the tumor to the first hospital visit, the
site of occurrence, size, heterogeneity in imaging examinations,
enhancement on enhanced imaging, the presence or absence of a capsule in
macroscopic findings, the presence or absence of recurrence, and a
follow-up period.
A statistical analysis was performed using the commercial software, SPSS
(IBM, Armonk, NY). A linear regression analysis was conducted to
investigate the relationships between two types of quantitative
parameters. The Mann-Whitney U test was used to examine differences in
quantitative parameters between two groups. Pearson’s chi-square test
was employed to analyze differences among qualitative parameters.P ≤0.05 was considered to be significant.
