[Trans-ethmoid encephaloceles]. / Les céphalocèles transethmoïdales.

We report two cases of ethmoidal cephaloceles. Ethmoidal cephaloceles are very rare and most commonly present with recurrent episodes of meningitis or sometimes as a nasal mass. Diagnosis is made at MR and CT. Such imaging studies should be obtained in patients with recurrent meningitis or patients with polypoid nasal lesions prior to biopsy.
