Abstract:
A 16-month-old male with mouth breathing due to intranasal mass and obstruction from birth is the subject of this report. CT (computerizd tomography) scan and MCTC (metrizamide CT cisternography) showed only a mass forming a cyst in the left nasal cavity, but magnetic resonance imaging (MRI) demonstrated the connection between the cranial content and the intranasal mass. The mass was concluded to be a congenital intranasal meningocele of a transethmoidal type, and dural plasty by bifrontal craniotomy was initially performed. The remaining herniated sac was removed by intranasal endoscopic resection. MRI has numerous advantages over CT. With MRI's multiplanar capability, there is no need for artificial dilution of the image of surrounding bone, and thus makes it the most valuable image technique for skull base lesions, making the diagnosis of intranasal meningocele much easier than it would be using conventional methods.
