“…[ 29 ] In the same study, the presence of the tumor does not directly alter the vessels; however, invasion of the SSS does alter the blood flow, suggesting that the diploic veins are used as an alternative route when the sinus is obstructed by the tumor lesion. [ 29 ] Accordingly, it is important to preserve both the wall of the SSS and the pathways used for alternative circulation in the event of tumor invasion.

“…Besides the risks arising from lesions of the SSS, Yamashiro et al ., 2021, noted that the presence of postsurgical deficit may be associated with the preservation of the diploic veins. [ 29 ] By comparing the surgical approaches with an invasion of the sinus and the nonpreservation of the diploic veins, the presence of new deficits was noted after the procedure, unlike in patients who did not suffer an invasion of the SSS; thus, the preservation of these vessels was made easier.

“…In a medical context, DV present a high risk for spreading infections, and any bleeding from DV can result in an acute subdural hematoma. DV may function as collateral venous pathways in patients with dural venous sinus invasion by meningiomas (Yamashiro et al, 2021). Rarely, diploic arteriovenous fistulas may also occur, usually due to trauma (Lachkar et al, 2019; Rivera‐Lara et al, 2015; Tsutsumi, 2020).…”

Diploic veins (DV) run within the cranial diploe, where they leave channels that can be studied in osteological samples. This study investigates overall DV variability in human adults and the effects of sex, age, cranial dimensions, and dysmorphogenesis associated with craniosynostosis (CS). The morphology of macroscopic diploic channels was analyzed in a set of the qualitative and quantitative variables in computed tomography-images of crania of anatomically normal and craniosynostotic adult individuals. Macroscopic diploic channels occur most frequently in the frontal and parietal bones, often with a bilaterally symmetrical pattern. DV-features (especially DV-pattern) are characterized by high individual diversity. On average, there are 5.4 ± 3.5 large macroscopic channels (with diameters >1 mm) per individual, with a mean diameter of 1.7 ± 0.4 mm. Age and sex have minor effects on DV, and cranial proportions significantly influence DV only in CS skulls. CS is associated with changes in the DV numbers, distributions, and diameters.Craniosynostotic skulls, especially brachycephalic skulls, generally present smaller DV diameters, and dolichocephalic skulls display increased number of frontal DV. CS, associated with altered cranial dimensions, suture imbalance, increased intracranial pressure, and with changes of the endocranial craniovascular system, significantly also affects the macroscopic morphology of DV in adults, in terms of both structural (topological redistribution) and functional factors. The research on craniovascular morphology and CS may be of interest in biological anthropology, paleopathology, medicine (e.g., surgical planning), but also in zoology and paleontology.

ObjectivePreoperative prediction of meningioma venous sinus invasion would facilitate the selection of surgical approaches and predicting the prognosis. To predict venous sinus invasion in meningiomas, we used radiomic signatures to construct a model based on preoperative contrast‐enhanced T1‐weighted (T1C) and T2‐weighted (T2) magnetic resonance imaging.MethodsIn total, 599 patients with pathologically confirmed meningioma were retrospectively enrolled. For each patient enrolled in this study, 1595 radiomic signatures were extracted from T1C and T2 image sequences. Pearson correlation analysis and recursive feature elimination were used to select the most relevant signatures extracted from different image sequences, and logistic regression algorithms were used to build a radiomic model for risk prediction of meningioma sinus invasion. Furthermore, a nomogram was built by incorporating clinical characteristics and radiomic signatures, and a decision curve analysis was used to evaluate the clinical utility of the nomogram.ResultsTwenty radiomic signatures that were significantly related to venous sinus invasion were screened from 3190 radiomic signatures. Venous sinus invasion was associated with tumor position, and the clinicoradiomic model that incorporated the above characteristics (20 radiomic signatures and tumor position) had the best discriminating ability. The areas under the curve for the training and validation cohorts were 0.857 (95% confidence interval [CI], 0.824–0.890) and 0.824 (95% CI, 0.752–0.8976), respectively.InterpretationThe clinicoradiomic model had good predictive performance for venous sinus invasion in meningioma, which can aid in devising surgical strategies and predicting prognosis.
