Background. Ependymomas are a group of glial tumours, usually occurring in the posterior cranial fossa, less often — in the lateral ventricles and spinal cord. Most often, the recurrence of ependymomas occurs in primary sites, or in the central nervous system (CNS). Ependymoma metastasis beyond the craniospinal system occurs rarely if ever.Description of a Clinical Case. A clinical example of extraneural metastasis to the bones and bone marrow in a 10-year-old patient with supratentorial anaplastic ependymoma after complex therapy has been presented. A review of published cases of the development of extraneural ependymoma metastasis in children has been presented. An attempt was made to consider possible risk factors for their development. Conclusion. Ependymal tumours are capable of extraneural metastasis to the bone and hematopoietic systems. Continued growth and metastasis lead to extremely unfavourable prognosis for the disease.

✓ Trigeminal neuralgia and hemifacial spasm were false localizing signs in three patients with contralateral space-occupying mass lesions in the posterior cranial fossa. According to radiological observations, the brainstem was remarkably displaced and distorted toward the side contralateral to the mass in all three cases. In the two cases with trigeminal neuralgia, the fifth cranial nerve was embedded in a thick arachnoid membrane and strongly compressed and angulated between the brainstem and the petrous bone, but there was no apparent vascular involvement. In the case with hemifacial spasm, only the contralateral tumor was removed. Postoperatively, all three patients experienced complete cessation of the symptoms without recurrence. Based on the operative findings, the authors postulate that angulation and distortion of the axis of the cranial nerve due to the contralateral mass, accompanied by thickening of the arachnoid membrane around the nerve, play an important role in false localizing signs, particularly in patients with trigeminal neuralgia.

Introduction. The problem of high mortality from cardiovascular diseases is caused, among other things, by asymptomatic atherosclerosis, which proceeds latently for a long time and manifests itself as a serious vascular catastrophe, which is of particular importance for people working at production facilities with difficult and dangerous working conditions.The aim of the study was to assess the risk factors for atherosclerosis and the state of the vascular wall in the workers of the main professions of coal enterprises in the South of Kuzbass.Material and methods. In total, the study included 384 people (men), of whom 266 were the workers in coal mines in the South of Kuzbass and 118 people who were not employed in the coal industry, aged 40 to 55 years. The diagnosis of atherosclerosis was carried out on the ultrasound system “Vivid E9” of the manufacturing company GE using a linear sensor for measuring the thickness of the intima-media complex and visualization of atherosclerotic plaques. To identify significant risk factors, anthropometric, anamnestic data, indices of lipid and carbohydrate metabolism, and the presence of arterial hypertension were studied.Results. Significant differences in the frequency of asymptomatic atherosclerosis in the form of an increase in intima-media thickness by more than 1 mm and / or the presence of atherosclerotic plaques in both groups were not found: 60.2% among the miners and 62.3% among non-coal mining workers (p=0.703); at the same time, the percentage of detection of atherosclerotic plaques in arteries was significantly lower among coal workers — 46.9% versus 60.5% among people in the comparison group (p=0.016). The common risk factors for all examined subjects were arterial hypertension and increased level of glycated hemoglobin; in turn, in coal miners additional risk factors were increased values of low density lipoproteins and waist-hip index, as well as burdened heredity for cardiovascular diseases, and among the individuals not employed in the coal industry it was smoking.Conclusions. The most significant risk factors for atherosclerosis in coal industry workers were arterial hypertension, raised values of glycated hemoglobin, low density lipoproteins and waist-hip index, as well as burdened heredity for cardiovascular diseases. Significant differences in the frequency of asymptomatic atherosclerosis in the form of an increase in the thickness of the intima-media complex of the main arteries and the presence of atherosclerotic plaques in both groups were not established, but the percentage of the detection of atherosclerotic plaques was lower among coal miners.The authors declare no conflict of interests.
