Abstract:
ObjectiveTo evaluate CT and MRI findings of the intrathoracic ganglioneuroma and to improve its diagnosis and differential diagnosis ability.MethodsClinical,CT( n = 14),MRI (n = 6) and pathology manifestations of 20 patients with the intrathoracic ganglioneuroma were retrospectively analyzed.All 20 cases had chest CT and MRI plain scanning and multiphase enhance scanning before operation.ResultsSeventeen of 20 lesions were located in posterior mediastinum,2 in pleura side and 1 in right thorax cavity.The CT value of the plain scans ranged from 20 to 40 HU ( mean 30.5 HU),Tubercle calcification were detected in four masses,one case with fat density was showed on CT scanning.After injecting contrast media,CT value ranged from 0 to 12 HU (mean 6.2 HU) in artery phase,ranging from 10 to 20 HU ( mean 14.3 HU) in delay phase.Five of 6 cases of MRI signals were homogeneously low intensity on T1 WI,1 case with fat signal was imhomogeneously low intensity on T1WI.Six cases were imhomogeneously high intensity on T2WI.A whorled appearance was visualized in one tumor on T2WI.The post-contrast enhancement MR images was slight enhancement imhomogeneously in artery phase and gradual increasing enhancement in delay phase.ConclusionOn CT and MR imaging,no enhancement or slight enhancement in artery phase and gradual increasing enhancement in delay phase are characteristic manifestations of ganglioneuroma in the thorax.
