While it can be idiopathic (Moyamoya disease) or associated with another condition (Moyamoya syndrome), there is a characteristic 'puff of smoke' sign that can be appreciated on cerebral angiography.

Acute stent malapposition poses a significant risk for adverse cardiac events following percutaneous coronary intervention. Detection of acute stent malapposition traditionally relies on intracoronary imaging techniques, such as intravascular ultrasound and optical coherence tomography, which may be limited in developing countries due to accessibility issues. A new angiographic sign called the has been introduced as a potential alternative for detecting malapposition during coronary bifurcation procedures.

Moyamoya angiopathy (MMA) is a progressive vasculopathy characterized by slowly progressive stenosis involving the proximal portions of the major intracranial arteries, resulting in strokes and intracranial hemorrhages. If it occurs secondary to a known cause, it is called Moyamoya syndrome (MMS). Here, we describe the case of a five-year-old male child who presented to us with symptoms of stroke and, upon evaluation, revealed Moyamoya angiopathy.
