A 36-year-old woman on chronic hemodialysis presented with sudden onset of headache and deterioration of consciousness. She was sent to our hospital on day 1, with subarachnoid hemorrhage. Cerebral angiography showed pearl and string sign on the left posterior communicating artery, which was consistent with a diagnosis of hemorrhage from a dissecting aneurysm of the left posterior communicating artery. She underwent parent artery occlusion via endovascular treatment on day 2. Although cone beam computed tomography before embolization showed a perforator from the lesion, there were no ischemic lesions on diffusion-weighted imaging after the procedure. She was discharged without any neurological deficits. It is important to recognize that dissecting aneurysm of the posterior communicating artery is one cause of subarachnoid hemorrhage. We also discuss the utility of cone beam computed tomography in formulating the treatment plan for such patients.

The circle of Willis (CoW) is a circular arrangement of arteries in the human brain, exhibiting significant anatomical variability. The CoW is extensively studied in relation to neurovascular pathologies, with certain anatomical variants previously linked to ischemic stroke and intracranial aneurysms. In an individual CoW, arteries might be absent (aplasia) or underdeveloped (hypoplasia, diameter < 1 mm).

Introduction: Posterior urethral valve (PUV) is a congenital condition marked by obstructing persistent urogenital membrane, leading to urinary tract infections, bladder dysfunction, and kidney damage. It affects males only, mostly suspected antenatally and confirmed in early infancy. It requires early diagnosis and intervention to prevent long-term complications.

Purpose: To describe a case in which a right replaced posterior cerebral artery (PCA) was associated with an ipsilateral superior cerebellar artery (SCA) type persistent trigeminal artery (PTA) variant.
Methods: A 53-year-old man who had been diagnosed with chronic dissection of the left vertebral artery (VA) 4 months previously underwent follow-up magnetic resonance (MR) angiography using a 3-Tesla scanner.
Results: MR angiography showed a slightly dilated left VA at the terminal segment without interval change.

Introduction: Down syndrome (DS) is associated with difficulties with feeding during infancy and childhood. Weaning, or transitioning from nursing to independent deglutition, requires developmental progression in tongue function. However, little is known about whether postnatal tongue muscle maturation is impacted in DS.

Not harming others is widely regarded as a fundamental tenet of human morality. Harm aversion based on the consequences of an action is called utilitarianism while focusing on the action itself is associated with deontology. This study investigated how interoceptive processing affects the neural processing of utilitarian and deontological moral decision-making.
