The excellent prognosis for patients with localized cervical neuroblastoma is demonstrated by the long‐term survival of six patients over 23 years. Surgical resection was accomplished in all patients with minimal residual tumor in five. Five patients received irradiation. Papillary carcinoma of the thyroid with node metastases developed in two of these patients 11 and eight years after treatment. This high incidence of secondary thyroid carcinoma has prompted reevaluation of the management of cervical neuroblastoma.
Five cases of intrathoracic kidney are presented, and the literature is reviewed. The diagnosis was made incidentally in 3 patients who had chest radiographs because of upper respiratory tract infections and in 1 infant on a follow-up radiograph after recovery from hyaline membrane disease. The fifth patient had an abdominal mass. All 5 patients had a left intrathoracic kidney, and 2 had a left Bochdalek hernia. An intrathoracic kidney should be considered in the differential diagnosis of a posterior mediastinal mass.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
