This article presents, based on the example of morphometric study of magnetic resonance tomograms of persons of various ages, the complex of vital characteristics of the cerebrospinal system of the brain in adolescents. The study tested gender characteristics and inter hemispheric asymmetry of the analyzed indexes. An asymmetry of anatomical structures of the right and left hemispheres with the tendency to increase in their sizes in the right hemisphere was found both for males and for females. Females had some age differences in the longitudinal dimension of the III ventricle (this index was lower in older females), the width and index of the IV ventricle was significantly lower in the 18 and 20 year old girls. Objective and methods. The research was conducted on the base of the radiation diagnosis department of Rivne Regional Clinical Hospital on the CT scan General Electric Healthcare Signa MRI 1.5 T and in the office of magnetic resonance imaging of Lutsk City Clinical Hospital on the CT scan Signa Profile Ce Medical System – 1,5 Tl in standard anatomic planes (sagittal, frontal andaxial). Measurements were carried out in persons without visual signs of organic lesions of the brain and skull. Analysis was made of 11 tomograms (males 17–21 years old – 6 persons, females 16–20 years old – 5 persons). In comparing pairs of parameters (of lateral ventricles) the factor of asymmetry was calculated, which is equal to the difference between the right and left lateral ventricles divided by the sum of right and left ventricles indexes (%). The results were processed by methods of descriptional statistics. In young males of this age group a significant increase in the following indicators was identified: the length of the anterior horn of the lateral ventricle on the right side, the length of the body of the lateral ventricle on both sides and the height of the III ventricle. Females had significantly increases in the following parameters: the width of the anterior horn of the lateral ventricle on the right side and the width of the posterior horn of the lateral ventricle on the left side. Consequently, in male adoles cents a parallelism in the formation of various structures of the ventricular system was traced. Since this is a single system, morphological and functional connections between its different components are stored. Mathematical analysis of the values of the structures of ventricular system in females characterize a hormonal influence on its development in adolescents. We can assume that organs which are the part of the circumventricular system (subcommisural organ, subfornical organ, median rise etc.), definitely have the character of anatomical connections between these components. Their functional unity in maintaining the homeostasis of the body is undeniable.

The introduction into medical practice of new methods of neuroimaging - computed and magnetic resonance imaging, has changed the principles of diagnosing morphological changes in the brain and opened up new horizons in the study of its structure. The literature sources provide conflicting and fragmentary data on the anatomical features and morphometric parameters of the parts of the brain, and especially its ventricular system, at different age periods of a person's life. The human brain is characterized by significant age-sex anatomical variability. It differs in men and women in different races, ethnic groups. Signs of difference persist from generation to generation and can be an important characteristic of the variability of the human brain as a species. However, the sex and age features of the structure of the cerebral ventricles, taking into account their individual anatomical variability, have not been sufficiently studied. During morphometric study of magnetic resonance tomograms a comprehensive in vivo characteristic of the cerebral ventricular system in elderly persons is presented. Gender peculiarities and inter-hemispheric asymmetry of relevant indicators are studied. The examinations were conducted in standard anatomical planes (sagittal, frontal and axial) in people with no visual signs of organic lesions of the brain and skull. 38 tomograms of elderly patients were analyzed 38 (14 men and 24 women). 13 indicators of the liquor system of the brain were studied and a significant increase of the following parameters were found in males: the length of the anterior horn of the right lateral ventricle, the length and width of the central part of the lateral ventricle both on the right and left, the length of the lower horn of the lateral ventricle on the left and right, and anterior-posterior size of the lateral ventricle on the right and left. Some of the parameters studied possessed reliable inter-hemispheric asymmetry, namely, in men on the left: the body width of the lateral ventricle, the length and width of the posterior horn of the lateral ventricle, anterior-posterior size of the lateral ventricle; in women – the length of the lower horn of the lateral ventricle on the right.

Cavernous angiomas (malformations) of the brain occur in 0.5% of the population. Most of them are asymptomatic, but due to their anatomical features, namely escape of blood into surrounding tissues, significant neurological symptoms can occur. The deep location of cavernous angiomas in the area of cerebral aqueduct makes surgical intervention difficult. Microsurgical approaches are the gold standard in removal of cavernous angiomas, but they are associated with certain surgical risks in the formation of the surgical corridor. Cavernous malformations in the cerebral aqueduct are a rare subtype. Due to anatomical localization and concomitant obstructive hydrocephalus ІІІ and lateral ventricles, they can be removed by endoscopic frontal transcortical transventricular approach. A 59-year-old patient was diagnosed with cavernous angioma of the brainstem (in the area of cerebral aqueduct) with hemorrhage and the formation of obstructive hydrocephalus ІІІ and lateral ventricles. The operation was performed: removal of the cavernous angioma in the area of cerebral aqueduct by endoscopic frontal transcortical transventricular approach on the right. Additionally, a triventriculocisternostomy was performed. Osteoplastic trepanation with centering at the Kocher’s point in size of 4 × 4 cm and the formation of a free bone flap was performed. The dura mater is cut in an H-shape. Approach to the anterior horn of the right lateral ventricle was performed. An intracerebral retractor was inserted into the anterior horn of the right lateral ventricle. Transforaminal approach to the tuber cinereum was performed - a triventriculocisternostomy was performed. Transforaminal approach to the cerebral aqueduct was performed and the cavernous angioma of the brainstem was removed. In the postoperative period, the patient had a slight deterioration in short-term memory, which regressed 2 weeks after surgery, an increase in oculomotor disorders, in particular persistent diplopia due to moderate paresis of the left oculomotor nerve. Three months after the operation, magnetic resonance imaging of the brain with intravenous contrast enhancement was performed. There are no signs of cavernous angioma. After the operation of frontal transcortical transventricular removal of cavernous angioma in the area of cerebral aqueduct, the compression of the latter was eliminated. Occlusive hydrocephalus regressed, the size of the ventricles decreased. Endoscopic frontal transcortical transventricular approach allows reaching the area of cerebral aqueduct in a less traumatic and minimally invasive manner. This technique is effective due to the low risk of surgical approach complications.

Abstract Background Although intracranial traumas by penetrating foreign objects are not absolute rarities, the nature of trauma, the kind of object, and its trajectory make them a one of a kind case every time they occur. Whereas high-velocity traumas mostly result in fatalities, it is the low-velocity traumas that demand an individualized surgical strategy. Methods We present a case report of a 33-year-old patient who was admitted to our department with a self-inflicted transorbital pen injury to the brain. The authors recall the incident and the technique of the pen removal. Results Large surgical exposure of the pen trajectory was considered too traumatic. Therefore, we opted to remove the pen and have an immediate postoperative computed tomography (CT) scan. Due to its fragility, the pen case could only be removed with a screwdriver, inserted into the case. Post-op CT scan showed a small bleeding in the right peduncular region, which was treated conservatively. The patient was transferred back to intensive care unit and woken up the next day. She lost visual function on her right eye, but suffered from no further neurologic deficit. Conclusion Surgical management of removal of intracranial foreign bodies is no routine procedure. Although some would favor a large surgical exposure, we could not think of an approach to do so without maximum surgical efforts. We opted for a minimal surgical procedure with immediate CT scan and achieved an optimal result. We find this case to be worth considering when deciding on a strategy in the future.

Abstract Here I try to improve on the available answers to certain long-debated questions and set out some consequences for the answers. Are there limits to the extent to which we can understand the conceptual worlds of other human communities and of non-human creatures? How does this question relate to our ability to engage in other cultures’ practices and languages? What is meant by ‘the body’ and what is meant by ‘the brain’ and how do different meanings bear on the questions? The central answer developed here is that it is possible, given the right circumstances, for a competent human from any human group to understand the culture of any other human group without engaging in their practices though there are barriers when it comes to communication across species. This answer has important social and political consequences and consequences for the debate about artificial intelligence.

BACKGROUND: Neuroimaging is increasingly used as a non-invasive method to assess raised intracranial pressure (ICP). Optic nerve sheath diameter (ONSD) measurement using brain magnetic resonance imaging (MRI) has been shown to correlate well with invasively measured ICP, however little research has been conducted on the ONSD measurement using computerized tomography (CT) in correlation with ICP. This study was done to investigate whether CT scan can reliably replace MRI in measuring ONSD.METHOD: A cross-sectional comparative study was conducted on 50 adult patients (29 females and 21 males), who underwent both CT and MRI of the brain along 10-month period. Using the brain axial section, the transverse ONSD was measured at 3 mm behind the globe in both modalities. Agreement between CT and MRI readings was assessed using intraclass correlation (ICC) and Kappa method.RESULTS: There was a strongly positive and statistically significant correlation between ONSD measurement using CT scan and MRI (p value <0.001). There was almost perfect agreement between CT scan and MRI in measuring ONSD (ICC=0.987 and Kappa =0.837). Similar agreement was obtained when cases stratified into normal (≤ 5mm) and thickened (> 5mm) ONSD (ICC=0.947 and 0.972 respectively).CONCLUSION: CT scan is a reliable substitute for MRI in measuring ONSD with almost perfect agreement between the two modalities. It might be good practice to include ONSD measurement in the initial evaluation of brain CT scan in any patient with suspected raised ICP.

Abstract A 21-year-old man with an oligodendroglioma in the anterior horn of the right lateral ventricle complained of sexual dysfunction and showed lowered concentrations of serum testosterone (1.1 ng/ml) with normal pituitary function. Human chorionic gonadotropin testing revealed a good testosterone response (1.1 to 4.9 ng/ml) and a clomiphene test revealed no gonadotropin response. Pulsatile secretion of luteinizing hormone (LH) was absent preoperatively. After removal of the tumor, serum concentration of testosterone increased to the normal range, LH pulsatility appeared, and the patient had no complaints of sexual dysfunction. In this patient, the loss of LH pulsatility responsible for his hypogonadism was caused by the lateral ventricle tumor compressing the surrounding structures, and this was corrected by tumor resection.

A 37-year-old woman, Para 5+0 presented with a 1 year history of recurrent convulsions and progressive weakness of the right side of the body. She had been treated for postpartum eclampsia in her last delivery but symptoms recurred 3 months later. Evaluation including computerized tomography scan of the brain suggested a parieto-temporal meningioma, which was completely excised at craniotomy. Histology confirmed this to be a meningioma. The patient was well at 8 months of follow up. The growth of meningiomas may increase during pregnancy due to presence of receptors for progestational hormones in the tumour and the meningioma may become symptomatic in pregnancy, presenting as eclampsia. Close follow up of patients with eclampsia is necessary to identify neurological features that may lead to a diagnosis of meningioma. Early diagnosis is essential if a good outcome is to be ensured.
