Based on the characteristic radiological findings and normal tumor markers a diagnosis of mediastinal teratoma was established. Intraoperatively it was observed that the mass had ruptured and

contents of the mass had spilled into the pleural cavity. Meticulous dissection ascertained the mass arising from the thymus which was removed after securing the thymic veins. Histopathology confirmed a mature teratoma. A characteristic CT

finding with normal tumor markers is diagnostic of pure teratoma at any site and this criterion was utilized for the diagnosis in the present case [1, 2]. Unfortunately,

despite the presence of the characteristic findings, our patient endured a biopsy and fluid aspiration which led to hydropneumothorax and the tumor rupture. Although the patient did not have an adverse event due to this, however, the spillage theoretically may increase the chance of relapse.
