RATIONALE
Extra-axial cavernous malformations (ECMs) arising from cranial nerves (CNs) are rare. Complete "en bloc" lesion resection and hemosiderin-stained tissue preservation remain the standard treatment, while a different strategy may be needed when the lesion is highly calcified . We report the 3rd calcified ECM-CN and review the clinical features and surgical strategy for this rare condition considering previous literature.
PATIENT CONCERNS
We present a 52-year-old woman with a calcified lesion located in the right lower 1/3 of the cerebellopontine angle.
DIAGNOSIS
The diagnosis was calcified ECM-CNs according to the pathological and radiological features.
INTERVENTIONS
A posterior midline craniotomy was performed, and piecemeal resection of the lesion was carried out. Subtotal resection of the lesion was achieved with a small piece left in situ.
OUTCOMES
No symptom or lesion-related recurrence was found during 28 months of follow-up.
LESSONS
Calcified ECM-CNs are unique cavernous malformations arising from CNs. Piecemeal resection and subtotal or near-total excision are 2 major aspects that differ from the surgical strategy for general ECM-CNs.
背景
起源于颅神经（CNs）的颅外海绵状畸形（ECMs）很少见。完整的“整块”病变切除术和含铁血黄素染色组织保存仍然是标准治疗方法，而当病变高度钙化时，可能需要不同的策略。我们报告了第 3 例钙化 ECM-CN，并结合以往文献回顾了这种罕见疾病的临床特征和手术策略。
患者关注
我们报告了一例 52 岁女性，其钙化病变位于桥小脑角的右下 1/3 处。
诊断
根据病理和影像学特征，诊断为钙化 ECM-CNs。
干预措施
行后正中开颅术，分块切除病变。总切除量为部分切除，一小部分留在原位。
结果
28 个月的随访中未发现症状或与病变相关的复发。
经验教训
钙化 ECM-CNs 是起源于 CNs 的独特海绵状畸形。与一般 ECM-CNs 的手术策略不同，其主要方面有两点，即分块切除术和次全或近全切除术。
