Superficial small cerebellar infarcts in cerebral amyloid angiopathy on 3 T MRI: A preliminary study.

Background: Strictly superficial cerebellar microbleeds and cerebellar superficial siderosis have been considered markers of advanced cerebral amyloid angiopathy (CAA), but there are few studies on cerebellar ischemic lesions in CAA. We investigated the presence of superficial small cerebellar infarct (SCI) ≤15 mm and its relation to magnetic resonance imaging (MRI) markers in patients with probable CAA.

Methods: Eighty patients with probable CAA were retrospectively evaluated.

Relationship of brain edema after deep brain stimulation surgery with motor and cognitive function.

Background: Some patients with Parkinson's disease (PD) develop peri-lead brain edema after deep brain stimulation (DBS) surgery. The influence of edema on neurological function is not well characterized. We investigated the relationship of brain edema after DBS surgery with motor and cognitive function.

[Dermatomyositis with squamous cell carcinoma of the lungs secondary to nivolumab treatment: a case report].

A 74-year-old man was administered nivolumab to treat recurrent squamous cell carcinoma of the lungs. He developed fatigue, redness on the front of his neck, muscle weakness, and difficulty in swallowing after receiving the third course of nivolumab. Physical and neurological examinations showed proximal limb muscle weakness, periorbital erythema, and erythema of the front of his neck as well as fingers.
