Abstract

BACKGROUND

Spontaneous regression is relatively rare in meningiomas. Since meningiomas are known to have a relationship with sex-related hormones, spontaneous regression cases related to sex hormones have been reported.

OBSERVATIONS

A 66-year-old man with a petroclival meningioma was radiologically followed up for 13 years. The tumor initially measured 2.535 cm3 and 2.521 cm3 on gadolinium-enhanced magnetic resonance imaging (MRI) and fast imaging employing steady-state acquisition MRI, respectively. However, the measurements decreased in the follow-up period to 0.977 cm3 and 0.98 cm3, respectively, demonstrating spontaneous regression of an asymptomatic meningioma located in a petroclival area. Continuous meticulous long-term follow-up revealed this phenomenon.

LESSONS

It is important to retain the option of conservative treatment for patients ineligible for surgery for reasons such as advanced age and coexisting diseases. https://thejns.org/doi/10.3171/CASE24416.

摘要

背景

脑膜瘤的自发消退相对少见。由于已知脑膜瘤与性激素有关，因此已有与性激素相关的自发消退病例报道。

观察结果

一名患有岩斜脑膜瘤的66岁男性接受了13年的影像学随访。在钆增强磁共振成像（MRI）和稳态采集快速成像MRI上，肿瘤最初体积分别为2.535 cm³和2.521 cm³。然而，在随访期间，测量值分别降至0.977 cm³和0.98 cm³，表明位于岩斜区的无症状脑膜瘤出现了自发消退。持续细致的长期随访发现了这一现象。
