摘要
目的:探讨甲状旁腺腺瘤的CT和MR表现,提高对其认识水平。方法:回顾性分析10例经手术病理证实的甲状旁腺腺瘤患者的临床、CT和MR资料。结果:10例甲状旁腺腺瘤,6例起源于下甲状旁腺,3例起源于上甲状旁腺,均位于气管食管旁沟内,1例起源于异位甲状旁腺。肿瘤最大径为1.0-4.0cm,平均2.8cm。肿瘤呈圆形或卵圆形、边缘清楚的结节或肿块影,6例CT表现为等密度,4例MR表现为T1WI低信号或等信号,T2WI等信号或高信号。8例轻至中度强化,2例明显强化。6例强化均匀,4例强化不均匀。7例有全身广泛性骨质疏松,其中3例合并棕色瘤。结论:CT和MR易于检出甲状旁腺腺瘤,可准确显示其部位、形态、大小及与周围组织的关系,并对多数腺瘤作出定性诊断,对临床诊治具有重要价值。
Objective:To investigate CT and MR features of parathyroid adenoma so as to improve the recognition of the disease.Methods:Clinical data,CT and MR images of 10 cases of parathyroid adenoma proved surgically and pathologically were retrospectively studied.Results:In all 10 cases of parathyroid adenoma,9 were located at asophagotracheal recesss,of which 6 were originated from inferior parathyroid gland and 3 were originated from superior parathyroid gland,1 was originated from ectopic parathyroid gland.Diameters of adenomas were 1.0~4.0 cm(2.8 cm on average).The adenomas were round or oval,well demarcated node or mass.6 cases showed isodensity on CT plain scan and 4 cases showed hypointense or isointense siganals on T1WI and isointense or hyperintense signals on T2WI.8 cases were slight-moderate enhancement and 2 cases were strong enhancement.6 cases presented with homogeneous and 4 cases presented with heterogeneous.General osteoporosis was complicated in 7 cases and Fibrocystic osteitis was found in 3 cases.Conclusion:CT and MR are easy to detect parathyroid adenoma,can precisely assess its location,shape,size and the relationship with surrounding structures.Most parathyroid adenomas could be accurately diagnosed with CT and MR therefore CT and MR are valuable for diagnosis and treatment of parathyroid adenoma.
