Abstract
BACKGROUND: To analyze the diagnostic value of computed tomography (CT), magnetic resonance imaging (MRI) combined with serum lactate dehydrogenase (LDH), neuron-specific enolase (NSE), carcinoembryonic antigen (CEA), and N-myc (MYCN) in the diagnosis of pediatric neuroblastoma. METHODS: Fifty-two children diagnosed with neuroblastoma were selected as the neuroblastoma group. During the same period, 52 children who visited our hospital with abdominal distension, diarrhea, constipation, and vomiting but were finally excluded from neuroblastoma were selected as the control group. CT and MRI were performed on all children. RESULTS: Fifty-two cases of neuroblastoma of the central nervous system were confirmed by pathological examination. The levels of LDH, NSE, CEA, and MYCN in the neuroblastoma group were clearly higher than those in the control group (P < 0.05). The results of CT and MRI combined with serum LDH, NSE, CEA, and MYCN were false positive in 10 cases and false negative in 6 cases, which were consistent with the pathological results. The sensitivity of CT and MRI combined with serum LDH, NSE, CEA, and MYCN in the diagnosis of neuroblastoma was notably higher than that of the three alone (P < 0.05). CONCLUSION: The imaging findings of CT and MRI in children with central nervous system neuroblastoma were definitely characteristic. MRI had higher diagnostic value than CT. The diagnostic value of CT and MRI combined with serum LDH, NSE, CEA, and MYCN was improved to some extent.
