垂体催乳素腺瘤(prolactin-secreting adenoma, PRLoma)是最常见的功能性垂体腺瘤,约占成人垂体功能性腺瘤的40%,泌乳素微腺瘤较为常见,很少发展为大腺瘤,最大直径大于40 mm的泌乳素巨腺瘤并不常见。本文报道1例43岁男性患者,检查颅脑CT初次发现鼻咽部肿物时显示鼻咽区占位54 mm × 55 mm,已达到泌乳素巨腺瘤标准。本文针对催乳素瘤的诊断、鉴别及治疗策略进行文献回顾。Prolactin-secreting adenoma (PRLoma) is the most prevalent functional pituitary adenoma, accounting for approximately 40% of adult functional pituitary adenomas. Prolactin microadenomas are relatively common and rarely progress into large adenomas. Prolactin giant adenomas with a maximum diameter exceeding 40 mm are infrequent occurrences. In this paper, we present a case study of a 43-year-old male patient diagnosed with a nasopharyngeal mass measuring 54 mm × 55 mm through craniocranial CT scan, which fulfills the criteria for prolactin giant adenoma. This article provides an overview of the literature concerning the diagnosis, differentiation, and treatment of prolactinoma.
目的制备新型栓塞剂——超顺磁性碘油(SPLIP),观察其用于经导管动脉栓塞(TAE)治疗兔VX2肝癌模型的安全性、有效性及MRI所示TAE栓塞肿瘤效果。方法制备新型栓塞剂SPLIP,观察其稳定性,比较制备当日与第30天MRI所示体外SPLIP T1和T2值。分别将10只健康雄性新西兰大白兔随机分为SPLIP组和常规碘油(C-LIP)组(每组5只)、10只雄性新西兰大白兔VX2肝癌模型随机分为SPLIP-A组和C-LIP-A组(每组5只),行TAE,对SPLIP组和SPLIP-A组注入0.6 ml SPLIP,C-LIP组和C-LIP-A组注入等量C-LIP,2周后对SPLIP-A组和C-LIP-A组行上腹部平扫CT及MRI,观察肿瘤影像学表现,评估SPLIP用于TAE治疗VX2肝癌模型兔效果;对比各组兔TAE前及2周后血清谷丙转氨酶(GPT)、谷草转氨酶(GOT)、血尿素氮(BUN)及肌酐(Cr)变化。结果所获SPLIP性质稳定;体外MR T1WI和T2WI均无信号,制备当日与第30天T1及T2信号值差异均无统计学意义(P均>0.05)。治疗后2周,SPLIP组与C-LIP组GPT、GOT、BUN及Cr均与治疗前差异无统计学意义(P均>0.05);MRI所示SPLIP-A组及C-LIP-A组碘油沉积范围及栓塞肿瘤效果与CT相符。结论SPLIP用于TAE治疗兔VX2肝癌模型安全、有效;利用MRI可清晰显示其栓塞肿瘤效果。
