Why Does the Fracture Not Heal? Vascular Channel Mimicking Skull Fracture
為何此骨折不能癒合?血管溝混淆顱骨骨折

KTP Hui, wmw Lam, MT Chau


Abstract

Vascular channel of the frontal bone is a rare anatomical variant. This report describes a child who suffered from head injury with right parietal skull fracture and another suspicious fracture at the right frontal bone. Follow-up computed tomography showed persistent frontal "fracture" while the parietal fracture had resolved. Post-processing with 3D volume rendering showed that it was actually not a fracture. While there is no accessory frontal suture reported other than the metopic suture, the most likely cause for the radiolucency here is vascular channel of the frontal bone. Image post-processing is very helpful in doubtful situation, and should be considered in addition to axial images in our daily practice.

額骨血管溝是罕見的解剖變異,本報告闡述1名小孩因頭部外傷伴右頂骨骨折,並懷疑右額骨骨折。電腦掃描隨診發現頂骨骨折已癒合,但仍存在額骨「骨折」。後期處理重構3D影像發現這並非真正的骨折,除額縫外,亦未見輔額骨縫。這透亮徵的最可能原因是額骨血管溝。在有疑問的情況下,影像後期處理應輔加在日常軸面影像的操作上。
