Natural history of asymptomatic cervical internal carotid artery stenosis in diabetes mellitus patients.

Introduction: Diabetes mellitus (DM) is known to be a cause of cervical internal carotid artery stenosis (ICS). In this study, we investigated the natural history of asymptomatic ICS in DM patients without surgical intervention.

Methods: We conducted a retrospective study of 148 DM patients with asymptomatic ICS treated medically at the Kansai Electric Power Hospital from April 2013 to March 2023, inclusive.

Twig-like middle cerebral artery as a variety of isolated middle cerebral artery disease with new vessel formation: illustrative case.

Background: Twig-like middle cerebral artery (T-MCA) is reported as a rare vascular anomaly characterized by reconstitution of the M1 segment of the middle cerebral artery (MCA) by a plexiform network of small vessels. Although it is generally believed that the etiology of T-MCA is an embryological persistence, some investigators have suggested that T-MCA may be a secondary consequence. Here, the authors report a second case of de novo T-MCA formation and reconsider the concept of T-MCA in connection with isolated MCA disease.

Moyamoya disease presenting with symptomatic ischemic stroke during new-generation tyrosine kinase inhibitor treatment: two illustrative cases.

Tyrosine kinase inhibitors (TKIs) have been widely used to treat chronic myeloid leukemia. Nilotinib and ponatinib, which are second- and third-generation TKIs, have been reported to cause cerebrovascular arterial complications. Here, we present two cases of moyamoya disease presenting with symptomatic ischemic stroke during new-generation TKI treatment.

A rare intracranial fusiform thrombosed aneurysm of the distal middle cerebral artery: A case report.

Background: Intracranial aneurysms of the distal middle cerebral artery are rare, and most etiologies are infection or dissection. We present an extremely rare intracranial fusiform thrombosed aneurysm of the distal middle cerebral artery with histopathological confirmation of a pseudoaneurysm.

Case Description: Our patient, a 68-year-old female, was previously healthy and had no history of infection or trauma.
