“…[8,21,24,26,28,30] The predominance of anterior (and medial) distribution of FCC corresponds to the opinion of most authors. [11,13,17,19,24,29,31] Using 178 FCC on medio-sagittal images of x-ray tomography Lanig [24] calculated a 99% probability that the anterior accumulation of FCC in his sample is not random. In contrast to observations made by Tsitouridis [13] considerably more cases of multiple FCC occurrences in one patient were discovered (about half of all patients examined).…”

“…[8] Few studies which also included histological examinations usually described FCC (except for occasional psammoma bodies) as a typical ossification. [10][11][12][13][14][15] Concerning the identification of intracranial calcifications, the CT is significantly superior to other imaging methods. [16][17][18][19] Only three CT studies could be found examining FCC frequency.…”

Background:The aim of this study is the acquisition of data regarding the frequency, position, size, sex-and age distribution of falx cerebri calcifications (FCC, including ossifications) using CT scans.Methods: An explorative-retrospective data collection using skull CT scans of all CT devices (in use for patient examinations) at the University Hospital Graz. From August 20 to August 31, 2015, 365 cases of undisturbed and non-contrast brain images were determined. FCC with a density threshold value of > = 100 HU was recorded, analysed according to certain target parameters and evaluated using descriptive statistics. Additionally, lateral views of three-dimensional image reconstructions of certain FCC were produced and measured. Also, superior sagittal sinus calcifications were examined. Results:The occurrence of FCC accounted for 34% in general and was slightly more frequent in older men. Among all FCC 95% were located in anterior and medial falx area. The Spearman's rank correlation between age and occurrence of FCC was r = .96, p < .001. Considering a sagittal dimension (max. length x max. height x sin (90°-Gantry Tilt) computed in axial layers) of > = 2cm² , FCC incidences still amounted to 9, 8%. Conclusions:The FCC frequency of 10% with a size of > = 2 cm² (sagittal dimension computed in axial layers) corresponded to values of previous x-ray studies. However, the dimension or diameter was never mentioned. FCC of the size mentioned above is relevant to an osteopath's work since they might influence the craniosacral palpation and treatment of the falx cerebri. Therefore, there is further need for investigation concerning the possible effects of FCC on craniosacral palpation of the falx cerebri, precise measurements of size, as well as a histological comparison alongside CTimaging. size determination than the sagittal dimension computed in axial layers.

“…They may also involve the choroid plexus of the lateral ventricles. Most often, such ossifications or calcification are clinically irrelevant and cause no neurological symptoms: neither focal deficit symptoms nor irritating symptoms -epileptic seizures [1][2][3]. They also do not cause increased intracranial pressure.…”

“…Most often they are accidentally diagnosed during head imaging examinations performed for various medical indications. The imaging test of choice, which most clearly shows ossification is computed tomography (CT) [3]. In CT, calcifications are clearly distinguishable from brain tissue and cerebrospinal fluid because they are definitely hyperdense.…”

Extensive ossification of the falx cerebri occur rarely however are described in the world literature references. Ossifications may concern both cerebral falx and other dural structures: tentorium. They are most often incidental findings and occurrence frequency in the population is remains unclear. The authors of the study are reviewing references on this subject, based on a case of extensive falx ossification. Manuscript describes the case of incidental detected of extensive calcification of the anterior brain sickle in a patient after head injury. Computed tomography revealed no pathology, but extensive ossification of falx was described. The patient did not complain of any significant complaints or neurological symptoms. The described calcification constituted a median and sagittal bone or calcium plate separating the frontal lobes of the brain. Analyzing references did not identify such extensive ossification of falx cerebri in human, however dural ossifications are reported in the references.
