Pituitary Metastasis from Renal Clear Cell Carcinoma:A Case Report

患者男性,51岁,因右侧肾透明细胞癌行右肾摘除术后21个月、右肾上腺转移性癌行腹腔镜肿瘤摘除术后8个月,出现头痛、多饮多尿、畏寒、纳差、双眼视力减退3个月,头颅MRI检查发现鞍区肿瘤而入院。经多学科讨论,认为该鞍区肿瘤以垂体瘤并卒中可能性大,但不排除垂体转移癌,需手术治疗,垂体转移癌临床极为罕见。经常规术前准备后行经右眉锁孔入路、鞍区肿瘤摘除术,术中肿瘤完全切除,术后病理证实为肾透明细胞癌垂体转移。

Pituitary metastasis is a rare disease and is easy to be misdiagnosed. In present article, we reported a case with pituitary metastasis from renal clear cell carcinoma. A 51-year-old male patient presented with headache, polydipsia, hyperdiuresis, cold intolerance, poor appetite, and vision defect for 3 months. The patient was undergone a resection of right renal clear cell carcinoma 21 months ago and an adrenal gland metastasis resection 8 months previously. Head MR scanning revealed a large mass in the sellar region. Multidisciplinary consultation considered a diagnosis of either a pituitary apoplexy or a metastatic disease. The mass in the sellar region was totally removed through a trans-eyebrow keyhole approach. Pathological examination confirmed the diagnosis of pituitary metastasis from metastasis of renal clear cell carcinoma.
