We report an extremely rare case of intracranial squamous cell carcinoma of the cerebellopontine angle. The patient underwent craniotomy for debulking of the lesion to relieve mass effect on the brainstem and to establish a tissue diagnosis. Cancer staging revealed no other primary cancers and no evidence of metastatic disease. Postoperatively, he received image-guided intensity-modulated radiotherapy to the tumor bed followed by fractionated radiosurgery boost to the gross residual disease for a total average dose of 7000 cGy. He had a complete response to radiation and remains 42-months' disease-free post-treatment.
我们报告了一例极其罕见的桥小脑角颅内鳞状细胞癌病例。患者接受了开颅手术以切除病变组织，减轻对脑干的占位效应并进行组织诊断。癌症分期显示无其他原发性癌症且无转移疾病证据。术后，他接受了针对肿瘤床的图像引导调强放疗，随后对大体残留病灶进行分次立体定向放射外科增敏，总平均剂量为7000厘戈瑞。他对放疗有完全反应，治疗后已无病生存42个月。
