Fallopian canal meningocele: report of two cases.
OBJECTIVE
The purpose of this study is to report 2 rare cases of congenital fallopian canal meningoceles.


METHODS
Magnetic resonance imaging, computed tomography (CT) of the temporal bone, CT-cisternogram, and combined transmastoid approach with middle fossa craniotomy in 2 patients.


METHODS
Radiologic and operative diagnosis of congenital fallopian canal meningoceles.


RESULTS
Presentations included spontaneous cerebrospinal fluid (CSF) otorrhea and recurrent meningitis with intracranial hypertension. Postoperative complications included facial nerve palsy and persistent CSF leaks that necessitated ventriculoperitoneal shunt and lumbar drain placement.


CONCLUSIONS
Use of CT of the temporal bone in combination with CT-cisternogram may define sites of active CSF leak. Intraoperative use of fluorescein may assist identification of cranial base defects to lower rates of recurrence, and intraoperative use of cranial nerve monitoring can minimize the risk of nerve injury during repair.
