Introduction: Intratumoral calcification is a feature that is more often observed in pineal parenchymal tumour than germinoma. We describe a 13-year-old male with pineal region germinoma demonstrating extensive intratumoral calcification. Case report: He presented with worsening headache that was associated with fatigue, nausea and vomiting. Radiologic examination revealed a multilobular mass in the pineal region with internal calcifications. Biopsy showed a pure germinoma with unusually extensive calcification. Discussion: Although a diagnosis may be suggested with a careful evaluation of imaging, there is no pathognomonic pattern. Thus, histologic verification is necessary for most pineal region masses.

A case of ectopic pinealoma in the region of the sellar trucica, which not enlarged reaiologically, so-called the intrasellar germinoma is described with its clinical manifestions, roentgenographic pictures, pathological findings and therapeutic points of view.

Recently we experienced stereotaxic endoscopic biopsy and resection of intracranial tumors using the Brown-Robert-Wells system. Surgical exploration was undertaken under the local anesthesia:1 germinoma in pineal region, 1 arachnoid cyst in basal cistern. The method is described, and the its potential clinical applications is discussed.

Although extra-axial hematoma is a well known complication in ventricular shunting, epidural hematomas(EDH) are not common in this setting. This is the report of an unusual case of acute EDH in a patient with hydrocephalus caused by pineal germinoma treated by ventriculoperitoneal(V-P) shunt and radiotherapy. The formation of acute EDH has been rarely reported as a complication of V-P shunt. We would like to share our experience with a case of acute EDH after 4 months of V-P shunt and a review of the literature is also included.

The diagnosis and treatment of pineal tumor has captivated the interest of neurosurgeons for decades. Reports indicated that the majority of these tumors were malignant and thereby couild not be surgically removed and decompressed without high mortality and morbidity. And the pineal tumor especially germinoma is one of the mosdt radiosensitive intracranial tumors. Therefore a regime of radiotherapy combined with ventricular shunting, to relieve hydrocephalus, was advocated. In addition, with development of C-T we make the diagnosis easily and assess the result of treatment. We report a pineal tumor which was treated completely by irradiation following ventriculo-atrial shunt.

The authors think that the more desirable treatment for pineal region tumors is definitive surgery with a histological diagnosis and that a conservative approach consisting of shunting and radiation therapy no longer seems to be appropriate. We report the result of a retrospective review of the presentation, treatment, and outcome of the seventeen patients treated between June, 1989 and June, 1994. Nine patients were males and eight patients were females, and the age ranged from 13 to 51 years(mean age about 32 years old). Histological verification was available in fourteen tumors;six by an occipital transtentorial approach and five by an infratentorial supracerebellar approach and two by a stereotaxic biopsy and one by a frontotemporal craniotomy for ectopic germinoma. Germinomas were the most common type. Three of the seventeen patients died of tumor progression. Because the great variety of tumor found in the pineal region must be treated in different ways and because improved microsurgical and stereotaxic surgical techniques have made mortality and morbidity rates acceptably low, a biopsy diagnosis should be obtained.

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.
