[Intraoperative ultrasonography of brain tumors].

The 6-years results are described of intraoperative ultrasonic imaging of the brain tumors and are compared with the results of preoperative computerized tomography. On the basis of 169 cases it was shown that the lesions well visible in preoperative CT (with or without contrast) were also well delineated in USG. In cases of presence in CT with or without contrast of extensive isodense or hypodense area, USG could localize in all patients the tumor with suggestion of its morphology.

[Clinically oligosymptomatic and diagnostically doubtful brain tumors in patients of the Neurology Department CSK MSW].

Three cases of brain tumours are reported in patients with clinical symptoms much too scant in relation to the extent of the lesion. MRI examinations were decisive for correct diagnosis and for tumour localization. Early brain tumour diagnosis by MR imaging may influence favourably prognosis in such cases.

[Surgically treated epidural hematoma of the spinal cord at the Th1-Th2 levels associated with arachnoid cyst].

In a man aged 28 clinical picture, myelography and computerized myelotomography demonstrated epidural haematoma at the level of Th1-Th2 vertebrae with associated arachnoidal cyst. Owing to initially erroneous diagnosis of transverse myelitis the haematoma was diagnosed only after 7 days and removed surgically with simultaneous evacuation of the cyst. The therapeutic result was minimal.

[A case of cerebral cysticercosis treated with praziquantel in the postoperative period].

A 51-year-old man with cerebellar signs and raised intracranial pressure had negative indirect and serological tests for cysticercosis. During operation cysticerci were removed from the cisterna magna, fourth ventricle and aqueduct. Histological examination confirmed the diagnosis of cysticercosis.
