Abstract:
Objective To evaluate the value of MSCT in the clinical diagnosis of pediatric mediastinal neuroblastoma.Methods MSCT findings of 1 3 cases of pediatric mediastinal neuroblastoma confirmed by surgical pathology were analyzed retrospectively. Results Posterior mediastinal masses were found in 13 cases,9 cases on the right,4 cases on the left side.Mass vertical diameter was longer than that on the horizontal diameter,in which the largest diameter was >5 cm in 1 1 cases,and ≤2.5 cm in 2 cases.On CT plain scan,low density necrotic liquefild area was showed in 6 cases,calcification in 6 cases.There were 1 2 cases of strengthening enhanced effect,obviously uneven enhancement in 8 cases,mild enhancement in 4 cases,no enhancement in 1 case.Signs of peripheral vascular infiltration of surrounding tissue were showed in 8 cases,trachea pressing shift in 5 cases,pleural liquid in 2 cases.There was chest vertebra destruction in 1 case and 1 case with femoral and tibial metastasis and renal metastasis.There were 2 cases of adrenal neuroblastoma concurrent with mediastinal neuroblastoma.CT diagnosis of neuroblastoma in 6 cases,neurogenic tumors in 5 cases,mediastinal occupying in 1 case.Misdiagnosed as anterior cyst in 1 case.Conclusion MSCT can not only show the location,extent and some pathological features of pediatric mediastinal neuroblastoma,but also can clear the degree of tumor invasion and can guide the clinical treatment and evaluate the therapeutic effect.
