Encephalocele is a protrusion of the intracranial contents through a cranium defect. Encephalocele is divided into primary (congenital) and secondary (acquired) classes. From an epidemiological point of view, primary encephalocele is much more prevalent than secondary cases. Furthermore, among the secondary causes of this condition, iatrogenic encephalocele is recognized as a rare phenomenon. In this case report, we introduce a case of secondary encephalocele in a 30-year-old pregnant female who came to our emergency center at 5 weeks of gestation with a vague headache in her forehead and a runny nose. she reported a history of nasal polypectomy 9 months ago and a 10-day hospitalization for meningitis 5 months prior to admission. MRI of the patient's brain showed evidence of cerebral parenchymal herniation to the right nasal cavity, which was suggestive of encephalocele. She was scheduled for endoscopic transnasal reconstruction, and during the operation, a significant right-sided posterior ethmoidal roof defect with CSF leak and encephalocele was revealed. Eventually, the skull defect was successfully repaired with a vascularized flap, and the patient was discharged in good general condition.
脑膨出是颅内内容物通过颅骨缺损的突出。脑膨出分为原发性（先天性）和继发性（后天性）两类。从流行病学角度来看，原发性脑膨出比继发性病例更为常见。此外，在这种情况的继发性原因中，医源性脑膨出被认为是一种罕见现象。在本病例报告中，我们介绍了一名30岁的孕妇，她在妊娠5周时因前额模糊头痛和流鼻涕来到我们的急诊中心。她报告9个月前有鼻息肉切除术史，入院前5个月因脑膜炎住院10天。患者脑部的MRI显示有脑实质疝入右侧鼻腔的迹象，提示脑膨出。她被安排进行内镜经鼻重建，手术中发现右侧筛窦后顶部有明显缺损，伴有脑脊液漏和脑膨出。最终，颅骨缺损通过带血管蒂皮瓣成功修复，患者出院时一般情况良好。
