Spontaneous regression of solid-cystic vestibular schwannoma: A case report

Mohamed Dahamou et al. Surg Neurol Int. .

Abstract

Background: Vestibular schwannomas (VSs) are one of the most common tumors of the cerebellopontine angle and internal meatus, the evolution of this type of tumors is defined as unpredictable, it can enlarge or present a spontaneous regression as described in rare cases.

Case description: We report the case of a 50-year-old woman who presented with a large right full cystic VS revealed by a balance disorder associated with deafness in the right ear which spontaneously regressed. The patient was lost to follow-up for 3 years, the symptomatology improved, and the tumor clearly regressed without any surgical treatment.

Conclusion: Spontaneous regression of solid-cystic VS is possible but rare, it can be part of conservative treatment, which requires regular follow-up.

Keywords: Cerebellopontine angle tumors; Solid-cystic vestibular schwannoma; Spontaneous regression.
