An aberrant left subclavian artery is a rare variant that has been reported to coexist with the right-sided aortic arch in many cases. We encountered a case in which percutaneous transluminal angioplasty using a stent was performed for an aberrant left subclavian artery and left carotid artery. ⋯ Despite difficulty in inserting a catheter at the origin of the aberrant left artery, the treatment was completed successfully. To our knowledge, endovascular treatment for an aberrant left subclavian artery has not been reported until date.

Here we describe a rare case of a pregnant patient with a ruptured aneurysm of the distal anterior choroidal artery(AChA)that was embolized using n-butyl cyanoacrylate(NBCA). The 32-year-old patient was 24 weeks pregnant. She suddenly suffered from headache and vomiting. ⋯ The rest of the pregnancy was uneventful. At 37 weeks, she delivered a normal baby by elective caesarean section. When treating pregnant patients with moyamoya disease and a ruptured cerebral artery aneurysm, it is extremely important to cooperate with obstetricians to ensure a safe pregnancy and delivery.

Case Reports
[Severe rhabdomyolysis and intracranial hemorrhage associated with synthetic cannabinoid: a case report].
A 28-year-old male presented with language and behavior disorders a few days prior to examination. Magnetic resonance images and cerebral angiography revealed an arteriovenous malformation (AVM) in the right frontal lobe. The size of the nidus was 2.0 cm, and it was fed by the middle cerebral arteries and drained by the superior sagittal and transverse sinuses. ⋯ SC refers to a variety of herbal/chemical mixtures, which mimic the effects of marijuana. Little data is available on the psychopathological and physical effects of SC. This is the first report of severe rhabdomyolysis and intracranial hemorrhage associated with SC use in Japan.

Case Reports
[Transient charles bonnet syndrome after excision of a right occipital meningioma: a case report].
Charles Bonnet syndrome is a condition characterized by visual hallucinations. These simple or complex visual hallucinations are more common in elderly individuals with impaired peripheral vision. The current report describes a case of transient Charles Bonnet syndrome appearing after the removal of a meningioma. ⋯ The release of pressure in the brain by tumor removal and subsequent recovery changed the blood flow to the brain. This triggered visual hallucinations in the patient, who was already predisposed to developing Charles Bonnet syndrome because of diabetic retinopathy. This case is interesting since it indicates that central neurological factors, as well as visual deficits, may induce the appearance of visual hallucinations in Charles Bonnet syndrome.
