Background In computer-aided intracranial aneurysm (IA) classification and segmentation, applications of 3D point cloud algorithms are increasingly widespread. However, the traditional point-based deep learning algorithm has the problem of poor segmentation effect. Methods An improved end-to-end depth network structure (N-PointNet) is proposed for IA classification and segmentation. First, the point cloud data of the IA are preprocessed. Then, the PointNet + + network structure is used as a backbone with learned hierarchical properties. After that, the preprocessed and resampled data produce multiple layers of information embedded in the original network input to further enhance its characteristics. Finally, a side output block is added, and the loss function of the corresponding layer is calculated. The multi-loss function facilitates fast convergence and improves model performance. Conclusion An experiment on the IntrA dataset proved the superiority of N-PointNet and obtained the best classification and segmentation results among the models tested. In addition, the proposed method has good generalization ability and has been verified on the common ModelNet40 dataset.

BackgroundThe primitive hypoglossal artery (PHA) is an anastomotic vessel of the carotid-basilar artery system that is prevalent only transiently during the embryonic period. Persistent primitive hypoglossal artery (PPHA) is a rare vessel variation in which PHA exists persistently in adulthood and occurs in approximately 0.02–0.1% of the population. Tortuosity of the extracranial internal carotid artery (ICA) is relatively common, impacting 10–43% of the population, and is caused by either congenital or acquired factors. It is still unknown whether PPHA and tortuosity of extracranial ICA are associated. Here, we present a case report of the concurrence of three types of pathologies of the carotid artery: extreme coiling of the extracranial internal carotid artery, multiple aneurysms and persistent primitive hypoglossal artery.Case descriptionA 66-year-old woman suffered intermittent headaches, dizziness and numbness of the right eyelid for 5 years. Magnetic resonance angiography performed in a local hospital reported an aneurysm of the posterior communicating artery segment of the left ICA and a left PPHA. Digital subtraction angiography conducted after admission showed a PPHA originating from the left cervical ICA and an extremely coiling segment of the ICA distal to the beginning of PPHA. Except for the aneurysm of the posterior communicating artery segment of the left ICA, multiple aneurysms were found at the coiling segment of the ICA.ConclusionTo the best of our knowledge, this is the first report of PPHA accompanied by an adjacent, extremely coiling ICA. There are no reports of similar tortuous ICAs to this extent or at this position. Including aneurysms, three types of pathologies suggest their congenital origin, and a review of the literature infers the probable association of these lesions.
