RESUMO
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. Intraoperative ultrasonic investigation is a valuable method supplementing preoperative diagnostic procedures, facilitating the localization of isomorphic tumors, reducing brain traumatization and making possible control of radical removal of the lesions.

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.

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 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. After operation the condition of the patient deteriorated consciousness disturbances, involuntary movements of the left upper extremity and paraparesis appeared. Only after treatment with Praziquantel with simultaneous administration of oedema-reducing agents nearly complete regression of neurological manifestations was achieved.
