Lymphocytic hypophysitis(LH) is a rare but increasingly recognized autoimmune endocrine condition that causes partial or total hypopituitarism and is often associated with peripartum young women.We here report a 28-year-old patient who had a spontaneous and uneventful pregnancy following LH that had been treated with transspenoidal surgery and followed by anti-inflammatory agent.The woman failed to lactate and developed frontal headaches 3 months after normal delivery of her first child 3 years ago.Lab test showed the reduced concentrations of thyroxine,estradial and cortisol,suggesting hypopituitarism.Magnetic resonance imaging of the brain with contrast was performed and showed a uniformly enhancing pituitary mass with elevated optic chiasm.She underwent transsphenoidal surgery and histological examination of the resected specimen was consistent with lymphocytic hypophysitis.Anti-inflamation was started with prednisolone 40 mg per day because of a recurrence of headache that had completely recovered after surgery and regularly withdrawn to a long term maintenance dose of 10 mg per day.Physiological thyroxine replacement therapy was maintained.Her menstruation was restored without sex hormone replacement after 3 months.Three years after surgery,she got pregnant spontaneously and had normal breastfeeding after delivery.LH did not recur during this peripartum.
目的探讨胰岛细胞瘤的临床特点、诊治方法及转归。方法回顾性分析2000年1月—2013年4月北京大学第一医院收治的18例胰岛细胞瘤患者的临床特点、诊断和治疗方法、转归等资料。结果 18例患者中,男女比为1∶2;年龄为18~83岁,中位年龄51岁。16例为功能性胰岛细胞瘤,2例为无功能性胰岛细胞瘤,功能性胰岛细胞瘤均为胰岛素瘤,其中2例合并糖尿病。胰岛素瘤患者临床上均有典型的Whipple三联征;血糖为0.85~2.56mmol/L,同时胰岛素水平>10 m U/L有16例,胰岛素释放指数>0.4有11例,胰岛素释放修正指数>100有14例。胰岛素瘤患者行B超检查11例,5例阳性;行增强CT检查14例,11例阳性。行B超、CT检查均阴性的3例患者分别经胃镜超声、经皮经肝门静脉置管分段采血测定胰岛素(PTPC)、剖腹探查术中B超及分段采血方法进行诊断。17例胰岛细胞瘤患者行手术治疗,其中行肿瘤局部切除术10例,胰腺体尾部切除术6例,Whipple术式1例。患者术后均未出现严重并发症,胰岛素瘤患者术后低血糖均恢复。结论胰岛细胞瘤以功能性胰岛素瘤居多,少数合并糖尿病,确诊需有典型的Whipple三联征、胰岛素水平测定及胰岛素释放指数定性诊断,增强CT定位检查阳性率高。胰岛细胞瘤良性率高,治疗以外科手术为主。
