Case Report: Occipital Mature Teratoma Mimicking Encephalocele in an Infant

INTRODUCTION: Intracranial teratomas are rare congenital neoplasms that typically arise in midline structures such as the pineal and suprasellar regions. Occipital region teratomas are exceedingly uncommon. CASE PRESENTATION: We report a case of a full-term neonate born with an occipital region mass initially presumed to be an encephalocele. Postnatal surgical resection revealed a mature teratoma. At eight months of age, the patient showed no evidence of tumor recurrence. CONCLUSION: This case illustrates the unique clinical and operative considerations in managing rare congenital occipital region lesions.
