A rare case of a trifid xiphoid process with two foramina was found incidentally. This anatomical variation highlights the importance of recognizing unusual sternum development for clinical awareness.
Area of Science:
- Anatomical variations
- Human anatomy
- Congenital anomalies
Background:
- The xiphoid process is the smallest part of the sternum.
- Variations in xiphoid process morphology are uncommon.
- Understanding anatomical variations is crucial for accurate diagnosis.
Observation:
- A 56-year-old man presented with an asymptomatic, ventrally curved, trifid xiphoid process.
- CT screening revealed two foramina within the trifid xiphoid process.
- The right process was 4 cm, middle 2 cm, and the xiphoid foramina measured 0.5 cm and 0.3 cm.
Findings:
- The xiphoid process exhibited a trifid structure with two superposed foramina.
- Detailed measurements of the xiphoid processes and foramina were recorded.
- No other musculoskeletal anomalies were detected.
Implications:
- This case provides insight into sternum development and anatomical variations.
- Recognizing such anomalies aids in clinical diagnosis and management.
- Further study of xiphoid process variations can enhance medical knowledge.
