    Description / Table of Contents: Summary A 54-year-old female patient with a 10-year history of ventriculoperitoneal shunt resulting from communicating hydrocephalus of undetermined aetiology is reported. Transient gait disturbances and cerebral infarction at the age of 46 did not lead to further insights into the nature of the disease. After many years with only occasional disturbances, a distinct organic brain syndrome developed. Thorough examination led to a tentative diagnosis of neurocysticercosis; this was based on the history, liquor diagnosis and cerebral microcalcifications in CT. Despite the initiation of specific therapy, the patient died of the sequelae of the disease. At autopsy, characteristic cicatricial residues of mainly basal leptomeningitis were found with collapsed parasitic cysts. Additional intracerebral mesenchymal-glial reactions were less conspicuous. Residual ependymitis had caused aqueductal stenosis. Death was due to cachexia, bronchopneumonia and a lung abscess. The clinical course and morphology of neurocysticercosis are discussed. The disease has become rare in our country, but is globally the most important parasitic disease of the central nervous system.
    Notes: Zusammenfassung 54 jährige Patientin mit bereits 10 Jahre altem ventrikuloperitonealem Shunt wegen eines ätiologisch unklaren Hydrocephalus communicans. Eine passagere Gangstörung und ein Hirninfarkt mit 46 Jahren führten zu keiner weiteren Klärung der Krankheitsgenese. Nach langjähriger Zwischenphase mit gelegentlicher Verwirrung der Patientin trat ein ausgeprägtes hirnorganisches Psychosyndrom auf. Eingehende Diagnostik ergab aufgrund der Anamnese, der Liquor- und der CT-Befunde mit nachweisbaren kleinen zerebralen Verkalkungen den Verdacht auf eine Neurozystizerkose. Die Patientin starb trotz eingeleiteter spezifischer Therapie an den Folgen der Erkrankung. Bei der Obduktion zeigen sich charakteristische narbige Residuen einer v. a. basalen Leptomeningitis mit kollabierten Parasitenzysten. Zusätzliche intrazerebrale mesenchymal-gliöse Residuen waren weniger auffällig. Eine abgelaufene Ependymitis war Ursache einer Aquäduktstenose. Todesursache waren eine Kachexie, Bronchopneumonie und ein Lungenabszeß. Diskutiert werden Klinik, Verlauf und Morphologie der Neurozystizerkose, die – bei uns selten geworden – weltweit die wichtigste parasitäre Erkrankung des ZNS darstellt.

    Notes: Abstract Congenital intracranial tumors are very rare and only account for 0.5–1.5% of all childhood brain tumors. Even rarer are those with prenatal manifestation. The most common of these present at birth are teratomas, which show divergent differentiation with 90% of them containing tissues from all three germ layers. We report a rare case of an intrauterine congenital immature teratoma in a female fetus at 23 weeks of gestation, which was sonographically diagnosed in vivo by detection of the tumor and associated craniomegaly. Because of the poor prognosis, termination of the pregnancy was induced by Rivanol instillation. The cerebral tumor was confirmed at autopsy and was not associated with any other malformations. Histological and immunohistochemical features of this tumor are presented.

    Notes: Abstract In 11 cases of intracranial, temporal arachnoid cysts the etiology, clinical and radiographic findings, surgical treatment, and outcome are reviewed in respect of post-traumatic subdural hematoma. Cysts of the middle cranial fossa are susceptible to trauma, which may cause bleeding either into the cyst or into the subdural space. Signs and symptoms of increasing intracranial pressure (ICP), local neurological deficits, and sometimes epileptic seizures may lead to hospitalization. CT or MRI scans are diagnostic in these cases. In cases of intracranial mass lesion with displacement of the midline structures and increasing ICP, osteoplastic craniotomy is performed and the lateral wall of the cyst is resected down to the tentorial notch by a microsurgical procedure, with opening into the basal cisterns. There were no operative or postoperative complications in 11 consecutive cases. However, one boy required a cystoperitoneal shunt 3 months later as a result of hydrocephalus following subdural hematoma. Asymptomatic arachnoid cysts are discussed with respect to brain function and social behavior.

    Notes: Abstract In the past, contradictory results have been reported concerning the specificity of neuronal or glial cell markers. However, we have investigated this aspect in a large group of more than 550 brain tumors (among them 60 medulloblastomas). These contradictions can easily be explained by considering two basic facts. First, every neoplastic cell population, especially in embryonic tumors, diffusely infiltrates the brain tissue: non-neoplastic cells, intermingled with tumor cells, can therefore give rise to immunohistochemical and histogenetic misinterpretations. Second, different cell markers can be expressed by one and the same cell (e.g., GFAP, NSE, vimentin), making nosological interpretation of the tumor difficult, impossible, or at best rather subjective. Clear-cut marker positivity is mostly found in the differentiated tumors for which the nosological classification is already clear by the usual histological methods. Only synaptophysin seems to be a reliable marker for neurogenic cells. In embryonic brain tumors (so-called PNET), no correlations between the presence of a given cell marker and the biological behavior of the tumor have so far been detected.
