[Tumors of the 3d ventricle, clinical aspects and treatment].

Our last 30 patients, who were operated upon 3rd-ventricle-tumors, are discussed on symptomatology, diagnosis and therapy. Depending on the localization we classify oral, basal and caudal tumors. The peak of these tumors is found in the first ten years of life. They are distributed as followed: spongioblastomas, ependymomas, pinealoma and other rare tumors. Mainsymptom is the sudden diffuse headache depending on this skull's position. The three groups show different symptomatic features, the oral one sepecially that headache described above. The symptoms of the caudal group are due to signs of raised intracranial pressure and content the typical syndrome of the lamina-quadrigemina. Basal tumors lead to diencephalic disturbances. The CT scan should be done as the first diagnostic step, eventually connected with ventriculography or ventriculotomography. In any case therapy should be started by implantation of an atrio-ventriculare shunt. If the disease is progressing an invasive procedure has to be done. Irradiation therapy is bound to a clear histologic diagnosis or to a clear inoperability. Our 5-years survival was 40% in average.

Supratentorial extracerebral cysts of the middle cranial fossa. A report of 23 consecutive cases of the so-called temporal lobe agenesis syndrome.

23 cases of supratentorial extracerebral cysts of the Sylvian fissure in children and adult patients are reported. There were 21 male and 2 female patients and the medial age was 15 years (range 2--60 years). The cysts were located in the left middle cranial fossa in 18 cases, in two cases there were bilateral cysts and three patients only had right-sided lesions. In 14 patients the presence of the cyst was uncomplicated. In two of these patients the cyst was detected only incidentally. Four patients had subdural haematomas in addition to the cyst. Two patients had subdural haematomas and were hydrocephalic as well. Three patients had large cysts and hydrocephalus. We did not encounter intracystic bleeding. Operation on the cysts by uncapping them was done in four cases. In all four instances histological examination of the cyst wall revealed that it was composed of arachnoid. Uncapping of the cyst was not followed by its diminution in any of the four patients. It seems that uncapping of such cysts is not a helpful treatment and that surgical treatment in our cases should have been restricted to complications such as subdural haematomas and hydrocephalus. A search for better operative methods for the treatment of large extracerebral supratentorial cysts of the middle cranial fossa should be undertaken.

Computerized axial tomography in chronic partial epilepsies.

EEG and CAT studies were performed in 187 adult chronic epileptics. Acute convulsions, known tumor epilepsies, and seizures due to a rapidly advancing neurologic disease were excluded. Partial seizures of elementary and complex symptoms were nearly equally frequent. In 48 patients the etiology of the seizure disorder remained unknown. Among the verified etiologies residual brain damage were the most significant. In 10 cases the chronic seizure disorder was due to slowly growing brain tumors. CAT findings were normal in 86 patients (46%) and abnormal in 101 (54%). Localizing signs could be demonstrated by neuroradiologic and/or radionuclide tests in 15.7%, by CAT in 28.9%, by neurologic examination in 58.3%, and by EEG in 78.1%. Localized CAT-pathology showed no correlation to the types of partial seizures, whereas a significant correlation could be established with residual brain scars and tumors and with localized neurologic or EEG findings. Epilepsy starting after the age of 15 is more likely to be linked with CAT-pathology than with seizure disorders starting in childhood.

Infections following tickbites. Tick-borne encephalitis and Lyme borreliosis--a prospective epidemiological study from Tyrol.

We present here a prospective study on infections following tickbites in military recruits in the province of Tyrol (Austria). 84 recruits experienced tickbites and underwent clinical and serological examination twice at four-week intervals for signs of tick borne encephalitis (TBE)-virus or Borrelia burgdorferi infections. 56 and 50 recruits could be evaluated for TBE-virus and Borrelia infection, respectively. Whereas no recruit was found with clinical or laboratory evidence of TBE-virus infection, two (4%) recruits showed an erythema chronicum migrans as primary manifestation of a Borrelia burgdorferi infection and 11 (20%) recruits had a significant increase in the titer of anti-Borrelia burgdorferi antibodies. Our results support the predominance of a subclinical course of a tick-transmitted borrelia infection in the population under observation, and shed some light on the epidemiological situation of tick-transmitted diseases in Tyrol.
