Intraosseous petrous apex schwannomas are an exceedingly rare entity; little is known about their epidemiology, natural history, and postoperative outcomes.
Here, we present the fourth known case of a primary intraosseous schwannoma of the petrous apex: a 68-year-old woman presenting with diplopia, facial numbness, progressive intermittent vertigo, tinnitus, diminished hearing, and ataxia. She underwent a transtemporal approach for subtotal resection of the tumor with subsequent stereotactic radiosurgery.
Our 2-year follow-up demonstrates slow growth and success of multimodal management in the treatment of these tumors. We review the 3 prior reports of petrous apex schwannomas and identify unifying radiographic and clinical characteristics to aid future diagnostic considerations of lesions of the petrous apex.
骨内岩尖神经鞘瘤是一种非常罕见的实体瘤；关于其流行病学、自然病史和术后结果知之甚少。
在这里，我们报告了第四例原发性骨内岩尖神经鞘瘤：一名 68 岁女性，表现为复视、面部麻木、进行性间歇性眩晕、耳鸣、听力下降和共济失调。她接受了经颞下入路行肿瘤次全切除术，随后行立体定向放射外科治疗。
我们的 2 年随访显示，多模态治疗在这些肿瘤的治疗中取得了缓慢的进展和成功。我们回顾了之前 3 例岩尖神经鞘瘤的报告，并确定了统一的影像学和临床特征，以帮助未来对岩尖病变的诊断。
