Today, the availability of noninvasive imaging procedures such as CT and MRI make it easy to diagnose, and some successful operative cases have been reported. We report three cases of neonatal brain tumors presented clinically within the first 2 weeks. Case 1: A full term boy admitted with projectile vomiting, enlarged head and left peripheral type facial palsy at the age of 12 days. CT scan revealed a large heterogeneous mixed-density mass in the left cerebellar hemisphere. Partially removed surgical specimen consisted of primitive glial cells differentiating with the ependymal cell immunohistochemically and electron microscopically, and diagnosed as ependymoblastoma. He had whole brain irradiation postoperatively, but died from respiratory distress 7 months later without tumor regrowth indicated on CT. Case 2: A full term boy admitted with progressive enlarging of the head at the age of 10 days. CT scan revealed a high-density mass in the cerebellar vermis and an obstructive hydrocephalus. Partially removed surgical specimen, diagnosed as medulloblastoma. He was irradiated throughout the whole brain and spinal cord, but died from intracranial dissemination 5 months later. Case 3: A 32-year-old female multipara was diagnosed as hydramnion during 28 weeks gestation. The concentration of AFP was very high in the amniotic fluid.

These primitive neuronal components are a good target for studying the morphology of primitive neuroectodermal tumors, including neuroblastoma, ependymoblastoma, medulloepithelioma and so on. Primitive neural tubes are immunohistochemically and ultrastructurally studied in two cases of primary immature teratoma of the child brains, compared to true rosettes in a case of neuroblastoma, primitive neural tube in the fetal rat brain (9 to 13 days of gestational age). The study also extends to the pathology of PNET. Ultrastructurally the primitive neural tube like structures in two teratomas were virtually identical those of developing fetal rat brains and true rosettes in a neuroblastoma. However, these tubular structures are different from each other in immunohistochemistry. These differences are considered to reflect the different developmental lineage of the tumor cells, that is, neuroblastoma produces only neuroblastic cells, and primitive neural tubes in teratoma both neuroblastic and glioblastic cells. Rejuvenation of neuroblastoma cells seems to render a VIM-positivity of the tumor cells.</p>","PeriodicalId":79360,"journal":{"name":"Noshuyo byori = Brain tumor pathology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19153228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
