Jugular foramen schwannoma in a child treated with complete surgical excision.

摘要

INTRODUCTION: A rare case of a large jugular foramen tumour presenting as a posterior fossa mass is described. MATERIALS AND METHODS: The patient, a 13-year-old boy presented with symptoms of raised intracranial pressure and on MRI imaging demonstrated the tumour origin within the jugular foramen, with appearances suggestive of schwannoma. He underwent a complete excision as a single-stage procedure thorough a lateral suboccipital craniotomy with minimal morbidity. Histology confirmed the diagnosis of schwannoma (WHO I). Jugular foramen schwannoma is virtually unheard of in the paediatric population. CONCLUSION: The differential diagnosis of a jugular foramen tumour includes tumours of the glomus jugulare, meningiomas, schwannomas, myxomas and chondrosarcomas. The imaging characteristics are important when considering this differential diagnosis.
