Anatomists and clinicians often encounter single bony anatomical variations in dry skulls and on imaging. However, a constellation of 20 such variants some that, to our knowledge, have not been previously described is noteworthy. Here, we describe an adult skull with multiple bony variations, and these are detailed and discussed. These included clival canals, an interclinoid bar with resultant foramen at the uppermost aspect of the clivus, middle clinoid process, posterior petroclinoid ligament, pterygoalar plate, septated hypoglossal canal, foramen through the anterior clinoid process, septated foramen ovale, shortened superior orbital fissure, and crista muscularis. Knowledge of individual differences in the structure of the skull may be of use to both anatomists and clinicians in the treatment of intracranial procedures as well as cranial imaging studies. Taken together, such a unique specimen is of archival value.
解剖学家和临床医生在干燥颅骨和影像学检查中经常会遇到单个骨骼解剖变异。然而，一组20种这样的变异（据我们所知，其中一些此前尚未被描述过）值得关注。在此，我们描述了一个具有多种骨骼变异的成人颅骨，并对其进行了详细阐述和讨论。这些变异包括斜坡管、斜坡最上方带有 resultant 孔的床突间骨桥、中床突、岩床后韧带、翼突板、分隔的舌下神经管、穿过前床突的孔、分隔的卵圆孔、缩短的眶上裂以及肌嵴。了解颅骨结构的个体差异可能对解剖学家和临床医生在颅内手术治疗以及头颅影像学研究中都有帮助。总的来说，这样一个独特的标本具有存档价值。
