<正>患者,女,60岁,因体检发现左肾门肿瘤1个月于2012年6月入院。外院CT平扫加强化扫描提示左肾实质萎缩变薄,左侧肾门可见较大类圆形软组织密度影,CT值约40HU,增强扫描动脉期病变呈明显强化,静脉期及延时期强化程度稍减低。左肾动脉、静脉受压移位。双侧肾上腺大小形态未见异常。考虑为左侧肾门区富血供肿物伴左肾萎缩(图1)。既往高血压病史6年,血压最高达190/100mmHg(1mmHg=0.133kPa)。口服酒     

膀胱嗜铬细胞瘤1例诊治并文献复习

目的 探讨膀胱嗜铬细胞瘤的诊治方法.方法 回顾性分析安庆市立医院泌尿外科2014年11月诊治的1例膀胱嗜铬细胞瘤患者的临床资料.结果 患者因"体检镜下血尿1月余"入院,泌尿系B超、盆腔CT及MRI示膀胱前顶壁占位灶.于全麻下行膀胱肿瘤电切术,电切除部分肿物时,血压急剧升高至225/114 mmHg,考虑为嗜铬细胞瘤,改行膀胱部分切除;肿物切除时,患者术中血压一度下降至90/60 mmHg.术中、术后按嗜铬细胞瘤处理,痊愈出院.手术标本经病理及免疫组化证实为膀胱嗜铬细胞瘤.随访30个月,患者血压正常.结论 膀胱嗜铬细胞瘤临床罕见,典型症状为血尿、排尿时头晕、心慌、血压升高,甚至晕厥,可借助B超、CT、MRI定位诊断,手术切除是首选治疗方法,术后应密切随访.

肾上腺组合性嗜铬细胞瘤四例报告及文献复习

Objective To discuss the clinical characteristics and management principles of com-posite pheochromoeytoma of adrenal gland (pheochromocytoma-ganglioneuroma). Methods Four cases of composite tumor of adrenal gland diagnosed pathologically were reviewed. All the cases were male, aged 37 to 62 years;three of them had the history of hypertension, one of them accompanied with paroxysmal palpitation, while one case was asymptomatic. Computerized tomography and ultra-sonography showed single tumor in adrenal, the diameter was about 2.5、3.8、6.3、15cm respectively. Two cases showed positive results in 131Ⅰ-metaiodobenzylguanidine (MIBG) scintigraphy. One case showed positive result in 99Tcm-hydrazinonicotinamide-3trysinoctreotide (HTOC) scintigraphy. Twenty-four hours urinary catecholamine examination revealed the average of norepinephrine, epi-nephrine and dopamine were (196.1±92.2)nmol/24 h, (26.6±8.9)nmol/24 h, (1957.9±913.5) nmol/24 h respectively. Two cases were at a little elevated level and the others with normal. All cases were managed with α-adrenergic receptor blocker preoperatively for 2-4 weeks. Results Tumor re-section was performed in all 4 cases, and 3 cases by retroperitoneal laparoscopy, one by open surgery. All 4 cases were diagnosed as composite pheochromocytoma of adrenal (Pheochromocytoma-gangli-oneuroma) by pathology. All patients had no evidence of recurrence or metastasis during follow-up from 15 to 38 months. Two of three cases with hypertension reverted to normotensive. Conclusions Composite pheochromocytoma of adrenal is rare, difficult to be diagnosed preoperatively. Except mild in eatecholamine secretion, which clinical manifestations are similar to pheochromocytoma. Pheochro-mocytoma-ganglioneuroma is no apparent tendency for aggressive behaviors, the results of surgical management are favorable.
