| ABSTRACT |
|
Intracranial germinomas are malignant neoplasms arising from remnants of primitive germ cells that have failed to migrate to the genital crest during embryonic life. They are usually solid tumors, but focal cysts may occasionally be found within them and are thought to represent proteinaceous fluid. Cystic degeneration of the whole tumor, however, that is caused by intratumoral hemorrhage, has not yet been reported. We present a case of cystic degeneration of solid suprasellar germinoma. During surgery, cyst content was shown to be liquefied hematoma, and bleeding of the tumor had occurred. The exact time of intratumoral hemorrhage in the presented case is unknown, but since there had been no episode of apoplexy, we believe that degeneration occurred chronically. The patient's postoperative course was uneventful. On the basis of our findings we suggest that in diagnosing suprasellar cystic tumors, the possibility of germinomas must be taken into consideration and that spontaneous cystic degeneration of suprasellar germinoma can occur as a result of tumor bleeding. |
