Posterior Mediastinal Thymus: Case Report and Literature Review
نویسندگان
چکیده
BACKGROUND The incidence of aberrant thymus in the posterior mediastinum is very uncommon. It is difficult to exclude malignancy before surgical procedure. CASE PRESENTATION In a six-month-old male coughing for two weeks prior to admission a posterior mediastinal mass was found incidentally by chest roentgenogram. Thoracotomy was performed. Histologic study revealed normal thymic tissue. CONCLUSION When a mass located in the posterior mediastinum, ectopic thymus should be included in differential diagnosis. Imaging techniques may spare thoracotomy. Ectopic thymus has a benign clinical course, and surgical resection is not recommended.
