Spontaneous regression of white epidermoid cyst of the pre-bulbar cistern in a 3-year-old child: a case report and literature review.

We describe the first case of regression of a white epidermoid cyst in a child. White epidermoid cysts are rare benign lesions, particularly in pediatric cases. Typically, these cysts need surgical resection. However, we report the case of a 3-year-old child with recurrent aseptic meningitis, in whom CT scan and MRI revealed a white epidermoid cyst in the pre-bulbar cistern. Surprisingly, over a 5-year follow-up period, the cyst showed dramatic regression without any symptoms. This case sheds light on the potential for spontaneous regression of white epidermoid cysts in children, challenging the need for risky surgical interventions. This report opens up new perspectives on the pathophysiology and management options for this type of lesion in children.
