Telovelar approach for microsurgical resection of an unusually located choroid plexus papilloma in the luschka foramen of an infant – Case report and review of literature

Abstract

Background: Choroid plexus tumors are rare intraventricular tumors. Most of these tumors are benign choroid plexus papillomas. Most common location of these tumors in pediatric population is lateral ventricle although posterior fossa located tumors are also reported. Tumors located within luschka foramen extending to cerebellopontine angle are extremely rare in this age. So, there are little data in the literature regarding optimal management and surgical approach of these tumors within this challenging location. Case description: We present an extremely rare case of choroid plexus papilloma of luschka foramen in an 8 months old boy extended laterally to cerebellopontine angle and pontomedullary junction. Tumor was resected successfully through telovelar approach without posing any injury to cerebellum, brainstem or cranial nerves. We also performed a review of limited literature available around different aspects of these tumors. Conclusion: Choroid plexus papillomas of luschka foramen in pediatric population, although rare, can be effectively resected through telovelar approach without posing any neurological sequels to patient.
