Metastatic Temporal Bone Tumor From Renal Cell Carcinoma Coexisting With Sphenoid Ridge Meningioma: A Case Report

Year: 2024

Type: article

Abstract: Metastatic renal cell carcinomas (RCC) of the skull are relatively rare. Here, we present a rare case of a skull tumor due to metastatic RCC coexisting with a sphenoid ridge meningioma. A 69-year-old man was followed up for a sphenoid ridge meningioma. He had undergone a laparoscopic right nephrectomy for RCC 10 years previously. He had a new tumor in the right temporal bone, which rapidly grew with bone destruction within a short period of five months. Both tumors had a common feeding artery, and embolization of the artery feeding the tumor was performed before tumor resection. Intraoperative findings and postoperative imaging of both tumors confirmed total resection. The histopathological results indicated metastatic RCC of the skull and meningothelial meningioma. Systemic radiological examination revealed a metastatic lung tumor, and the patient was transferred to another hospital with a modified Rankin scale (mRS) score of 2 for chemotherapy. The presence of meningioma could have induced the development of metastatic bone tumors via a common feeding artery. It is effective to perform embolization of the artery feeding the tumor before tumor resection.
