%X OBJECTIVE: Atraumatic cerebrospinal fluid (CSF) rhinorrhea is uncommon in children and necessitates a multi-disciplinary evaluation for an etiology. Underlying osseous abnormality due to extensive or multifocal low flow vascular anomaly should be considered as a potential cause of spontaneous CSF leak. Treatment of multifocal low flow vascular anomalies may include medical and surgical approaches. In this series, we seek to determine the presenting signs and symptoms and medical and surgical treatment options for multifocal or extensive low flow vascular anomalies.
METHODS: A retrospective case series at a quaternary care children's hospital was compiled. All children with CSF rhinorrhea diagnosed and treated for multifocal low flow vascular anomalies at our institution were included. A total of four patients were identified.
RESULTS: All four patients had delay in initial diagnosis of underlying cause of meningitis and CSF rhinorrhea. Average age at diagnosis of multifocal low flow vascular anomaly was 7 years. This was on average 4 years after initial presentation for medical attention. Treatment approach was multidisciplinary and included medical management with sirolimus and bisphosphonates as well as surgical approaches to the skull base (lateral and anterior) to prevent CSF egress.
CONCLUSIONS: Consideration of multifocal low flow vascular anomaly should be included in any pediatric patient presenting with CSF rhinorrhea.
