PURPOSE: The purpose of this study was to evaluate the morphology of xiphoid process by dissection and using radiography of cadavers and multidetector computed tomography (MDCT) in patients. METHODS: The xiphoid processes of 41 cadavers were dissected and taken by radiography. Other 902 patients examined by MDCT were revealed by image post-processing used with multiple planar reconstruction, maximum intensity projection and volume rendering. RESULTS: Xiphoid processes displayed pointed shape in 422 cases (44.75 %), oval shape in 387 cases (41.04 %), and forked shape in 134 cases (14.21 %). The sagittal shape of the xiphoid process was observed as ventrally deviated in 217 cases (23.01 %), dorsally deviated in 191 cases (20.25 %), S-shaped (ahead ventral, then dorsal) in 21 cases (2.23 %), and resembling a hook in 14 of ventral deviated patients and in 19 of those dorsal deviated patients. The foramen of xiphoid processes was found in 544 cases (57.69 %). The pattern L (a large foramen with a diameter of more than 5 mm) appeared in 302 cases (55.51 %), pattern S (a small foramen with a diameter of no more than 5 mm) in 155 cases (28.49 %), pattern LS (a mixture of a large and a small foramina) in 37 cases (6.80 %), and pattern SS (two or more small foramina) in 50 cases (9.19 %). CONCLUSION: Human xiphoid process appeared in morphological diversity. The anatomic structure and ossification degree of xiphoid process was well evaluated by MDCT. Our data may be used for diagnosis and surgical treatment of xiphoid process-related diseases.
