Mediastinal malignant lymphoma is generally a homogeneous tumor and a cystic variant is ver y rare. We report a rare case of mediastinal malignant lymphoma showing a cystic shadow. A 59-year-old man was referred to our hospital for further examination of tumor shadows in the left mediastinum on chest X-ray film. Chest computed tomography (CT) scan and magnetic resonance imaging (MRI) revealed a cystic shadow in th e left anterior mediastinum and two nodular shadows in the upper mediastinum. We suspected thymus, related anterior mediastinal tumor and lymph node swelling, so we performed resection of the tumor. Histological examination revealed a diffuse large B cell lymphoma, and a cystic part on chest CT scan (and chest MRI) was proved to be a component with necrotic tissue. Adjuvant chemo-radiotherapy was performed and there have been no findings of recurrence 22 months after the operation.
