[Diagnosis of otogenic abscesses of the brain using computed tomography].

Basing on 9 cases of otogenic cerebral abscess formations and on the literature data the authors discussed the value of CT contrast medium enhancement depending on the infusion technique and the time of performing sections. Correlation between visualising annular shadows identified as an abscess capsule and the technique of CT imaging has been shown.

[Techniques for imaging cystic changes in the kidneys].

The purpose of this communication is to assess difficulty in differentiation of various cystic formations in kidneys according to such imaging techniques as urography assisted by tomography, USG, CT. Magnetic resonance imaging was also included on the basis of reviewed publications. Study consisted of 67 patients aged 19-82, both sexes; all cases were clinically and operatively verified. According to our experience it seems that USG should be a primary technique in detecting fluid formations which meet criteria to be simple cysts. Differentiation of other types of cysts like inflammatory, haemorrhagic, complex or neoplasmatic cysts is more difficult. In these cases CTscan and fluid density assessment of present contrasted scans should be performed because of the fact that cyst walls are usually atypical and complex. Correlation of the two relatively less expensive techniques like USG and CT give us a higher degree of diagnostic sensitivity which can be compared with sensitivity of MR imaging. Diagnostic efficiency of urography depends on a size and localization of the cyst in correlation to calicopelvic system.

[The problem of recognizing venous thrombosis in renal cancers].

The authors, basing on their own experience and literature data, discuss possibilities of recognizing preoperative thrombosis of vena cava inferior and renal vein in patients with kidney cancer. The material comprises 86 patients of both sexes, aged 25-82 years with operatively and microscopically verified renal cancer. Combined examinations (urosonography, USG and CT) showed the presence of venous thrombosis in 15% cases. Diagnostic value of individual techniques differed from case to case and, therefore, we think that the best diagnosis results can be obtained by using combined imaging techniques.

[Traumatic hydrocephalus in children in CT images].

CT examinations were performed on 38 children who had suffered from perinatal trauma or a later injury. The recognised changes were classified as early or distant consequences of sustained head trauma. Special attention was paid to the time elapsing from the moment of injury to the occurrence of hydrocephalus and to the evolution of changes observed in the check-up CT examinations. The occurrence of zones of diminished periventricular density was correlated with the results of fluid drainage therapy. Atrophic changes of the cerebral nervous tissues were analysed in combination with the development of porencephalic traumatic fluid cavities.

The role of CT-imaging in recognizing the type of hydrocephalus and porencephaly in children.

Intrauterine USG examination becomes more and more important in diagnosing developmental lesions of cerebral nervous tissue. However, CT-imaging is a method of choice, especially after parietal closure (13, 16). The character and etiology of porencephaly, congenital or acquired, is diversiform and often difficult to recognize (18). This paper presents an attempt at assessing different forms of porencephaly, taking into account congenital hydrocephalus in children by means of CT-imaging.
