INTRODUCTION: Meningoencephaloceles are herniations of the meninges, cerebrospinal fluid, and/or brain beyond the cranial cavity resulting from a bone defect. Purpose: This article reports a rare case of idiopathic meningoencephalocele of the temporal bone with a slightly suggestive clinical picture, as well as the technique used for repair. Methods: Data were obtained through a review of medical records, an interview with the patient, a review of records of diagnostic methods the patient has undergone, and a literature review. CONCLUSION: Spontaneous meningoencephaloceles are rare, with an incidence of approximately 8.6% among meningoencephaloceles. This case illustrated the diversity of clinical presentations of idiopathic meningoencephalocele of the temporal bone, demonstrating its rarity, the difficulty of making the diagnosis in the presence of a suggestive clinical picture, and additionally warning about the importance of considering it in the differential diagnosis in cases of recurrent meningitis.
