Insights
A midline sternal foramen is a rare chest anomaly. This study found this foramen in 4.3% of patients undergoing computed tomography (CT) of the thorax.
Area of Science:
- Anatomical variations
- Medical imaging
- Thoracic anatomy
Background:
- The sternum, a central bone in the chest, can present anatomical variations.
- A midline sternal foramen is a rare congenital anomaly of the sternum.
Purpose of the Study:
- To report the incidence of midline sternal foramen detected via computed tomography (CT).
- To highlight this anatomical variation in thoracic imaging.
Main Methods:
- Retrospective analysis of thoracic CT scans.
- Identification and documentation of midline sternal foramina.
Main Results:
- Six cases of midline sternal foramen were identified.
- The incidence of this anomaly was found to be 4.3% in the studied patient cohort.
Conclusions:
- Midline sternal foramen is an uncommon finding in thoracic CT.
- Awareness of this anatomical variation is important for radiologists interpreting chest imaging.
Abstract:
Six cases of a midline sternal foramen were found with CT. This anomaly occurred in 4.3% of patients who underwent CT of the thorax.
