Intranasal meningoencephalocele presenting as a nasal polyp--a case report.

We present a case of an intranasal meningoencephalocele masquerading as an 'intranasal polyp' in a 17-month-old child. Nasal meningoencephaloceles are uncommon anomalies and require a high index of suspicion for their diagnosis. Biopsy of such lesions without prior imaging studies can be detrimental because of the risk of cerebrospinal fluid leak and meningitis, and is therefore contraindicated. This case reiterates the fact that any child with an intranasal mass should undergo appropriate imaging studies prior to excisional biopsy.
