Mature Cystic Teratoma in the Mediastinum

Abstract

This case is a presentation of mature cystic teratoma (MCT) in the mediastinum. A 24-year-old female presented with acute, sharp, and non-radiating chest pain, and anxiety. Her lab findings were significant for elevated WBC, ESR, and CRP. X-ray and CT scans of chest revealed a fatcontaining mass in the anterior mediastinum extending to the lung and compressing the pulmonary artery. The mass was subsequently resected via thoracic surgery. Further pathology study revealed skin folds establishing the diagnosis of MCT. This case emphasizes the need for clinicians to include mature cystic teratomas in the differential diagnosis.
