Abstract
Introduction: Mediastinal teratoma is a disease that develops silently and can reach large sizes asymtomatically. Computed tomography is a gold standard for diagnosis and treatment strategy. We report a case of radical surgical resection of an immature mediastinal teratoma. Case report: A 18 year-old male patient admitted to the hospital due to shrotness of breath. Contrast-enhanced computed tomography showed a mediastinal tumor of 132 x 135 x 200 mm. The tumor occupied nearly the entire left pleural space, compressed the heart and its large blood vessels to the right. The tumor was entirely resected via the median sternotomy. The pathology result was immature teratoma. Postoperative course was favorable, the patient was discharged from the hospital on postoperative day 7. Conclusion: Immature teratoma is a malignant disease with poor long-term prognosis. Surgery is a proven effective treatment. Initial successful results at a provincial hospital contribute to helping the surgical team develop techniques and continue to perform complex surgeries, the patients need not to travel long distances and thus decrease the treatment cost.
