Abstract

We report here a case of a primitive neuroectodermal tumor involving the frontal skull base in a 5-month-old male infant. He presented with rapidly progressing exophthalmos on the left side. Preoperative magnetic resonance imaging revealed a well-demarcated, enhanced mass of 6 cm in diameter in the intradural extra-axial frontal region. The tumor was totally removed by surgery. Pathological findings were consistent with a primitive neuroectodermal tumor (PNET). Intradural extra-axial PNET is very rare, and its prognosis is poor.

Abstract

We herein describe a case of thymoma in which metastasis to the left lower visceral and parietal pleura was noticed after a 2-year dormancy. A closer examination revealed no evidence that the metastatic tumors were of lymph node origin. The initial thymoma was well encapsulated, and thus it was thought that the development of metastasis might have reflected a sudden rapid growth of the thymoma cells after a 2-year period of inactivity.
