Abstract

Background: The skull base depicts significant morphological variability, which is frequently described due to its neurosurgical significance. The middle cranial fossa's accessory foramen has rarely been described.

Materials: A 53-year-old female patient's computed tomography (CT) scan was further investigated for its unusual morphology.

Results: On the left-sided middle cranial fossa, an accessory sphenoidal foramen (ASF) was observed, located 3.3 mm posterior to the foramen rotundum (FR) and 5.5 mm anterior to the foramen ovale (FO). Extracranially, the ASF opened into the infratemporal fossa and coexisted with another sphenoidal emissary foramen (SEF), anteromedially to the FO. On the right side, two SEF were located anteromedially to the FO.

Conclusions: Similar to the current case, ASF of the middle cranial fossa were reported in a previous study with a prevalence of 0.20%. The unconstraint well described accessory foramina are the emissary foramina that transmit emissary veins, and are of interest for anatomists, radiologists and neurosurgeons.

计算机断层扫描发现颅中窝的副蝶孔。

背景：颅底表现出显著的形态学变异，由于其神经外科意义而经常被描述。颅中窝的副孔很少被描述。资料：我们对一位53岁女性患者的计算机断层扫描（CT）进行了进一步的研究，发现其形态异常。结果：在左侧颅中窝，在圆孔（FR）后3.3 mm和卵圆孔（FO）前5.5 mm处观察到副蝶孔（ASF）。在颅外，ASF进入颞下窝，并与另一个蝶窦特使孔（SEF）共存，位于FO的前内侧。在右侧，两个SEF位于FO的正中前方。结论：与本病例相似，先前的研究报告了中颅窝ASF的患病率为0.20%。无约束的副孔是传递传递静脉的代理孔，是解剖学家、放射科医生和神经外科医生的兴趣所在。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
