Spontaneous regression of cysts of the cavum septi pellucidi (CSP) and cavum vergae (CV) is rare and little discussed. The authors present their case report of this phenomenon following a severe headache in a 23-year-old woman, in whom magnetic resonance imaging (MRI) had previously confirmed significant thinning of the left lateral cyst wall. We consider this finding to be a possible predisposing factor to rupture and the spontaneous regression of such cysts. In addition to the mechanism of cyst regression, the interrelated causes of their expansion and formation will be discussed.

OBJECTIVE: Cysts of the Cavum septi pellucidi (CSP), cavum vergae (CV) and cavum veli interpositi (CVI) are anterior midline intracranial findings which are typically incidental - only rarely do we encounter symptomatic cysts of this type. Only a quite small number of these cysts series have been published, controversies regarding optimal management still exist. PATIENTS AND METHODS: This is a retrospective study of 10 patients treated at 2 clinics between 2002-2018. 9 patients underwent surgery and 1 is under long-term monitoring. Apart from demographic data, the study analyzed symptoms, cyst size and progression over time, ventricle size, complications, and treatment modality. RESULTS: CSP with CV was found in 8 cases with 1 case each of CSP and CVI. The study comprised 6 men and 4 women, including 4 children. The mean follow-up time was 43.4 months. The average cyst size was 20.4 mm in CSP and 19.8 mm in CV; the CVI was 33 mm. Headache was most commonly reported (70%) followed by behavioral disturbance (30%). Disturbance in memory, psychomotor development, school performance, visual acuity, and vomiting was variously noted in 20%. The prevailing symptom was headache in adults and behavioral and autonomic disturbance in children. Postoperatively, cysts had reduced by an average of 44.3% while the ventricles remained unchanged. Symptoms resolved in all cases with residual problems in patients presenting with memory loss. No complications were noted. CONCLUSION: Endoscopic fenestration is the method of choice in the treatment of symptomatic midline cysts. We recommend that any further research focuses on precisely establishing their clinical presentation, particularly neuropsychological symptoms.

Recent data suggest that there is interaction between peripheral angiotensin II and nitric oxide. However, sparse information is available on the mutual interaction of these two compounds in the brain. The potential intercourse of nitric oxide with brain neuropeptides needs to be substantiated by assessing its local production and gene expression of the synthesizing enzymes involved. The aim of the present study was to evaluate whether the gene expression of brain nitric oxide synthase (bNOS) is related to the sites of gene expression of different components of the rat brain renin angiotensin system (renin, angiotensin converting enzyme (ACE) or angiotensin receptors of AT1 and AT2 subtypes). The levels of corresponding mRNAs were measured and correlated in nine structures of adult rat brain (hippocampus, amygdala, septum, thalamus, hypothalamus, cortex, pons, medulla and cerebellum). As was expected, positive correlation was observed between renin and angiotensin-converting enzyme mRNAs. Moreover, a significant correlation was found between brain NO synthase and AT1 receptor mRNAs, but not with mRNA of the AT2 receptor, ACE and renin. Parallel distribution of mRNAs coding for bNOS and AT1 receptors in several rat brain structures suggests a possible interaction between brain angiotensin 11 and nitric oxide, which remains to be definitely demonstrated by other approaches.

Dorsal lesions of the septum influenced the maternal behaviour of Wistar and Long-Evans females, as well as of their hybrids, in a different way. The phenomenon of infanticide appeared in Wistar females only, whereas mothering was not impaired in others. However, the mouse-killing activity was not enhanced in Wistar females displaying infanticide. On the contrary, they exhibited xenoparental behaviour. If these females had grown up in a species-typical environment, characterized by enriched social stimulation during their critical developmental period, no impairment of maternal behaviour following dorsal septal lesions occurred. The ablation of the whole septum caused a break-down of maternal behaviour with the appearance of infanticide in all females regardless of their stock origin and their individual life history. The specific role of the septum in the control of maternal behaviour is discussed.

Inspired by current knowledge of the possible participation of monoamines in the origin of schizophrenia and by experimental experience with embryonic nerve tissue transplantations, the authors ventured implantation of a human embryo's nervous tissue into a schizophrenic's brain. Six cubic millimeters of the transplant were placed in the septal area of both hemispheres. The substantial improvement of the clinical picture and, particularly, distinct improvement of memory abilities in the patient can more likely be attributed to the effect of the transplant rather than to the simultaneous mechanical intervention in the target structure of the recipient's brain.

The role of the septum in the regulation of blood pressure was studied in adult female and male laboratory (Alderley Park strain of Wistar) rats allowed a free choice between water and a 0.9% or 3% NaCl solution or simply given water. A lesion was formed in the dorsal septum and 30-66 days afterwards the mean arterial pressure was measured in the unanaesthetized animals' tail. In females the blood pressure was not affected either by the lesion itself, or by the lesion combined with a raised NaCl intake. In males, combination of the lesion with a raised salt intake was accompanied by elevation of the blood pressure, which attained values considered to be hypertensive (over 20 kPa). The increase occurred after 9 days' free choice between water and 3% NaCl solution preceded by 14 days' free choice between water and saline. At the same time, the computed NaCl concentration in the total fluids intake was higher in the control and septal females than in the control and septal males for both the salt regimens. Three days after changing from a free choice regimen to plain water intake, the blood pressure of septal males had fallen to normal values. After a protracted water regimen (43 days after discontinuing free choice), these animals had a lower blood pressure than sham-operated males after the same interval. The determinant variable in the effect of a dorsal septal lesion on the blood pressure in the presence of a hypertensogenic stimulus (NaCl) was the sex of the experimental animals.

The authors studied biopotentials in the region of the amygdala and the septum of rats fed on a standard, high protein or high fat diet. During the first 3-6 days after changing from the standard to the high protein or high fat diet, a decrease in the amplitude of electrical activity was found in both the regions in question. After 3 days on the high fat or the high protein diet, an increase was found in the frequency of electrical activity in the amygdala or the septum, according to the type of diet. A study of the amplitude of electrical activity showed that the electrical potential in the septum was always lower than in the amygdala. The frequency spectrum analysis showed a marked change in the superimposed frequency curve only in animals fed on the high fat diet.

Male laboratory rats prematurely weaned on the 15th day of life exhibited in adulthood an increase in seizure susceptibility in the septum, hypothalamus and hippocampus. The resting EEG of these animals exhibited characteristic changes demonstrated in the EEG spectrum power density by shifts in the power of individual frequencies. The administration of RNA to adult prematurely weaned animals affected in all structures under study the seizure susceptibility as well as the resting EEG, having caused in septum and hippocampus the return to values found in normally weaned rats. In hypothalamus the administration of RNA also changed the state given by the premature weaning but the return to normalcy was not complete.
