[Iatrogenic nasal meningocele: a cause of recurrent meningitis].

We present a 35-year-old male patient with an eight-year history of endoscopic nasal polypectomy followed by five episodes of meningitis (4 episodes in the past 3 years). His major complaints were right-sided nasal obstruction, frequent watery nasal discharge, headache, and fever. Physical examination revealed a mass in the right nasal cavity. Computed tomography and magnetic resonance imaging demonstrated a defect in the cribriform plate and an ethmoidal meningocele. The patient was referred to the neurosurgery department for surgical reparation.
