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 ..., Population 
 
This study targeted patients who visited the internal medicine outpatient department of Kameyama Municipal Medical Center between January 2021 and September 2023 with complaints of chest pain or abdominal pain. Case group were defined as patients diagnosed with xiphodynia who underwent CT scans including the xiphoid process. Diagnosis of xiphodynia was defined as meeting all of the following criteria: (1) presence of chest or upper abdominal pain, (2) reproducible tenderness upon palpation of the xiphoid process, (3) absence of other conditions more likely than xiphodynia as the cause of pain, and (4) improvement of pain with local injection of anesthetic agents onto the xiphoid process or xiphoid process excision surgery. Control groups were defined as patients who underwent CT scans including the xiphoid process and were diagnosed with other conditions than xiphodynia as the cause of pain. Patients with unknown causes of pain were excluded from the control group.

This is a dataset from a case-control study that evaluated CT sings of xiphoid process associated with xiphodynia. 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. Data collected from the medical records and CT images. CT examinations were utilized to measure signs of interest. Sagittal images were created, incorporating the xiphoid process from the thinnest axial section.
