Data from: A case-control study evaluating CT signs of xiphoid process associated with xiphodynia

Objectives：To investigate whether CT signs of the xiphoid process, such as
xiphisternal angle and evidence of soft tissue compression, are useful for
diagnosing xiphodynia. Design：A case-control study within a cohort.
Setting/Participants：Participants included 1560 individuals who visited a
small urban hospital in Japan for chest or abdominal pain between January
2021 and September 2023. Those who underwent CT examinations including the
xiphoid process were selected. Nine individuals diagnosed with xiphodynia
were assigned to the study group, while 321 individuals diagnosed with
other causes of pain were assigned to the control group. Interventions：The
xiphisternal angle, evidence of soft tissue compression anterior to the
xiphoid process, anatomical features at the tip of the xiphoid process,
and anatomical morphology of the xiphoid process were compared between the
two groups. Results：There was no significant difference in the
xiphisternal angle between the two groups. No significant differences were
observed in evidence of soft tissue compression anterior to the xiphoid
process or anatomical features at the tip of the xiphoid process. New
anatomical signs reveal that in approximately 70% of cases, the xiphoid
process curves forward and then backward.Xi Conclusions：The xiphoid
process sternal angle is not useful for diagnosing xiphodynia. The
curvature of the xiphoid process is frequently observed regardless of the
presence of xiphodynia.
