Evolution of a large intracranial artery dissection on multimodal neuroimaging with spontaneous healing

Excerpt

A previously healthy 17-year-old male adolescent with intermittent mild headache for 4 years and more severe for a week was admitted to our hospital. A previous magnetic resonance imaging (MRI) performed 9 months prior to hospitalisation had shown no abnormalities (Fig. 1a). On current neuroimaging studies consisting of brain computed tomography (CT), MRI with magnetic resonance angiography (MRA), and digital subtraction angiography (DSA) examination, a large intracranial artery dissection (IAD) was detected. Given the lack of subarachnoid hemorrhage (SAH) or ischemia, and the perceived risk of endovascular or surgical treatment, preference was given to close clinical and radiological observation and antiplatelet medication for the patient and the dissection spontaneously healed over the next 8 months.
