Prompt diagnosis and management of a ruptured mediastinal cystic teratoma

Abstract

Mediastinal germ cell tumors are some of the less frequently encountered anterior mediastinal masses. We report an interesting case of a 26-year-old male with a ruptured mediastinal cystic teratoma. Initial plain radiograph and CT scan of the chest showed radiographic evidence of a ruptured cystic teratoma, including a peripherally enhancing, partially calcified mass with internal fat density. Upon surgical excision, the mass was found to adhere to the thymus and anterior aortic arch. The patient was promptly diagnosed via imaging and managed in a timely manner via complete surgical resection.
