ABSTRACT

OBJECTIVES: Describe the diagnosis and management of lateral skull base (LSB) cerebrospinal fluid (CSF) leaks originating from the lateral ventricle.

STUDY DESIGN: Retrospective case review.

SETTING: Tertiary referral academic center.

PATIENTS: Patients with CSF leaks with direct communication to the lateral ventricle on preoperative imaging.

INTERVENTION: Surgical repair via the middle cranial fossa (MCF) approach.

MAIN OUTCOME MEASURES: CSF leak patient characteristics (age, sex, body mass index [BMI]) and postoperative course (complications and CSF leak resolution) were collected.

RESULTS: Three patients had CSF leaks from the lateral ventricle and all patients demonstrated encephalomalacia of the temporal lobe on preoperative imaging. Encephalomalacia resulted from trauma in one case (age 5) and neurodegenerat ion in two cases (age 77 and 84). BMI ranged from 16.3 to 26.6 mg/kg2 and follow-up ranged from 4 to 21 months. Two patients presented with preoperative meningitis and all patients had resolution of CSF leaks after MCF repair. With the exception of the higher rate of meningitis, patient presentations did not differ from other spontaneous CSF leaks through middle fossa defects. There were no minor or major postoperative complications.

CONCLUSIONS: CSF leaks from the lateral ventricle represent a rare subset of LSB CSF leaks and can occur in non-obese patients secondary to temporal lobe encephalomalacia. The MCF approach allows for repair of the dura and skull base in this cohort of patients with high-flow CSF leaks and loss of brain parenchyma.
