(1) This astrocytoma demonstrates increased cellularity and pleomorphism, as compared to normal brain.

(2) Objective To investigate finding of cerebella astrocytoma and to improve the diagnosis ability for this disease.

(3) Results Eighteen cases were astrocytoma, 2 cases meningioma, 2 cases oligodendrocytoma and 1 case was acoustic nerve tumor.

(4) The incidence of umbilicated indentation in astrocytoma, cerebral metastases and brain abscess was nearly the same, showing no value in qualitative diagnosis.

(5) Results There were 7 cases with anaplastic astrocytoma, 3 cases with glioblastoma multiforme, 1 cases with oligodendroglioma, 1 cases with lower grade glioma.

(6) Conclusion The result suggest that anaplastic astrocytoma and gemistocytic astrocytoma are more malignant and more recurrent.

(7) Objective To investigate the MRI finding of cerebella astrocytoma and to improve the diagnosis ability for this disease.

(8) Common data model: astrocytoma model snowflakes model, Constellation model, snow waterfall model.

(9) Objective To study the MRI and the differential diagnosis of brain metastasis, astrocytoma and brain abscess.

(10) If so, please look carefully for eosinophilic granular bodies and other features of pilocytic astrocytoma.

(11) The differential for a posterior fossa mass in children includes juvenile pilocytic astrocytoma, medulloblastoma, ependymoma, and brainstem glioma.

(12) Methods: MRI findings in 41 patients and pathologically proved astrocytoma were retrospectively analyzed.

(13) The differential diagnosis of brainstem tumor for a patient with this age includes astrocytoma, intramedullary ependymoma, medulloblastoma and choroid plexus papilloma.

(14) Objective To explore the clinical, pathological, radiological characteristics and surgical experience of pilocytic astrocytoma.

(15) Results: Our study sample consisted of 87 cases of ependymoma, 41 of astrocytoma, 16 of hemangioblastoma, 8 of cavernous haemangioma, 6 of lipoma, 8 of other uncommon intramedullary tumor.

(16) The tumors were diagnosed by postoperative pathological analysis including 6 ependymomas, 1 astrocytoma, 1 oligodendroglioma, 1 neurilemmoma, 1 arachnoid cyst.

(17) It is not necessary to perform auxiliary therapy for astrocytoma, oligodendroglioma, and mixed glioma, because the prognosis is good after total removal of the tumor.

(18) The top three differentials for this patient include hemangioblastoma, astrocytoma, and metastasis.

(19) Objective To investigate the pathology and clinical characteristics, radiological appearence and the therapeutic experience of pilocytic astrocytoma .

(20) Aim : To explore the morphometric grading method in the diagnosis of astrocytoma.

(21) This tour will examine the left parietal lesion, found at biopsy to be anaplastic astrocytoma.

(22) Results The most common neoplasms were medulloblastoma and ependymoma and astrocytoma in the fourth ventricular. Some tumors had specific patients age.

(23) There were no new lesions, worsening hydrocephalus, evidence of increased intracranial pressure, or necessity for surgical resection or other therapy for subependymal giant-cell astrocytoma.

(24) In our series, the incidence of various ventricular neoplasms (shown in decreasing order) were metastasis, astrocytoma, ependymoma, meningioma, choroids plexus papillomas and oligodendroglioma .

(25) Glioma is the most common type of primary intracranial tumors in human. It developed from astrocytoma, oligodendroglioma, ependymoma, which were induced by neural ectoblast.

(26) OBJECTIVE : To study the clinicopathologicae, immunohistochemical characteristics and prognosis of subependymal giant-cell astrocytoma ( SEGA ).

(27) But the sign can not be found in all 32 cases with intra-cerebral glioma, including 21 cases with astrocytoma and 4 cases with oligodendroglioma and 7 cases with ependymoma above cerebellar tentorium.
