[Diagnostic studies of optic neuritis in children and adolescents].

PURPOSE: To evaluate the sensitivity of various diagnostic methods in the optic neuritis. MATERIAL AND METHODS: 15 patients, 10 boys and 5 girls, aged 6-18 years, with optic neuritis have been examined. Multiple sclerosis was diagnosed in 12 cases, the etiology of 3 was unknown. The full ophthalmological examination, including static perimetry and visual evoked potentials (VEP) as well as brain computed tomography (CT) and magnetic resonance imaging (MRI) were performed. RESULTS: MRI revealed plaques of demyelination in 11 patients; no pathological changes were observed in cases of idiopathic neuritis. In CT plaques of demyelination were found in 2 patients only. In most cases VEPs were abnormal, mainly there was prolonged latency of deflection, decreased amplitude and more rarely changes of the shape of the record. Static perimetry, with white and blue target, revealed multiple scattered absolute and relative scotoma in the 30 degrees central area. CONCLUSIONS: MRI and static perimetry were the most sensitive methods for detection of the changes in optic neuritis and these methods are also useful in cases with asymptomatic involvement of visual pathway, especially in multiple sclerosis.

[Diagnostic value of computer tomography of paranasal sinuses in qualifying for functional endoscopic sinus surgery (FESS)].

Functional endoscopic sinus surgery (FESS) introduced in the recent years by Messerklinger, Stammberger and Kennedy gained undisputable reputation as method of choice in treatment of nose and nasal sinus diseases. The introduction of this method was possible, among others, due to precise radiological diagnostics (CT). Traditional radiological examinations of nasal sinus do not allow for detailed diagnostics and analysis of anatomic anomalies such as: dehiscention in vicinity of carotic artery or ophtalmic nerve which have basic significance while establishing surgical risk. The paper presents 20 cases of nasal sinus CT of patients qualified for functional endoscopic surgery comparative analysis with traditional radiograms were performed.

[Magnetic resonance imaging in otolaryngology].

In the paper authors describe fundamental physical properties of a phenomenon of the radio-frequency excitation and relaxation of nuclei ordered in a strong magnetic field and the usefulness of MRI in medical diagnostic procedures. Basic interpretations principles of MR imaging due to signal intensity differences between organs and tissues in T1- and T2- weighted sequences and proton density are presented. Both, literature review and experience of authors suggest application of MRI in otolaryngology, it is illustrated by a lot of examples. The MR imaging studies were compared with results obtained from CT in otolaryngology field.

[Laryngocele].

A large laryngocele treated operatively is presented. The great diagnostic value of CT examination for determining the size and site of the cyst is pointed out. A CT scan makes it possible to choose the best surgical procedure.

[Epileptic seizures in young patients with hypodense lesions in the CT image].

Progress in neurodiagnostic medical technology, and in computer tomography in particular, has raised fresh problems in connection with epilepsy. Among our patients we have observed three case of epilepsy, in whom the CT image unexpectedly revealed hypodense lesions of various sizes in the cerebrum. The three are young patients aged 20 to 25 years with negative neurological findings. The above changes in the CT image are extremely difficult to interpret. It is not even know whether the lesions must be considered the cause or a consequence of the epileptic seizures or whether the pathomorphological processes are basically identical or completely different in all three patients.

The diagnostic value of computerized axial tomography (CAT) in focal epilepsy.

The material of the Computerized Tomography Laboratory of the Institute of Radiology in Poznań concerning patients with focal epilepsy deals with more than 200 cases. In this paper we present 84 cases with verified etiology in the Neurosurgical Department. There were 39 cases of partial epilepsy of simple symptomatology, 28 cases of partial epilepsy with complex symptomatology (temporal) and 12 cases of secondary generalized epilepsy. CAT performed in 62 patients proved to be most adequate in the brain tumors and in atrophic lesions, than posttraumatic and postinfective lesions, less valuable in vascular diseases and degenerative processes.
