  • Title: Distant pseudomeningoceles of the ventral skull base: a report of 2 cases.
    Author: Lieberman SM, Ojo RB, Casiano RR.
    Journal: Int Forum Allergy Rhinol; 2013 Dec; 3(12):1021-4. PubMed ID: 24343990.
    Abstract:
    BACKGROUND: The objective of this case series was to report what is to the best of our knowledge the first reports of nasopharyngeal and soft palate pseudomeningoceles tracking submucosally from the sphenoid sinus. METHODS: Analysis of cases through medical records. RESULTS: Two cases of middle-aged male patients presented to our tertiary care university teaching hospital for recurrent meningitis and a history of cerebrospinal fluid (CSF) rhinorrhea. Both were found to have pseudomeningoceles distant from the sphenoid sinus. One was tracking to the mucosa of the Eustachian tube, and the other to the dorsum of the soft palate. Both were found to be tracking submucosally from the sphenoid sinus, to the vidian canal, to the lateral nasopharyngeal wall, to their respective locations at the Eustachian tube and dorsum of the soft palate. CSF closure was performed with a transnasal endoscopic repair using the pedicled nasoseptal flap for 1 patient and Alloderm for the other, both with successful cessation of CSF rhinorrhea. CONCLUSION: We present these cases of distant spontaneous CSF leaks. We review the literature and discuss case management.
