Abstract

Thymomas are common primary mediastinal neoplasms. They can be benign or malignant. The diagnosis of malignant thymomas is based on capsular invasion, cellular atypia and distant metastases. We present a case of invasive malignant thymoma as diagnosed on PET and CT scan with histologic correlation and review of literature. A seventy year old Asian man presented with cough and dyspnea. A CT scan showed an anterior mediastinal mass, and a PET scan showed a hypermetabolic mass in the corresponding location. Resection of the mass revealed a minimally invasive thymoma based on evidence of capsular invasion. PET scan proved invaluable in correctly diagnosing, staging the lesion, and excluding any extramediastinal involvement.
