Abstract

Objectives:

The objective of this case report was to describe a rare presentation of corkscrew cerebral angiopathy presenting as subarachnoid hemorrhage (SAH).

Methods:

We present a young woman who presented with a thunderclap headache, found to have a nonaneurysmal SAH.

Results:

Cerebral angiogram revealed corkscrew angiopathy in medium-sized vessels and multiple micro-occlusions with collateralization. No intracranial aneurysm was detected. Extensive workup for vasculitis and genetic causes for vasculopathy was unrevealing. The patient had no neurologic deficits, and her symptoms resolved.

Discussion:

This is an extremely rare presentation of subarachnoid hemorrhage due to corkscrew angiopathy.

The Arch of Aorta

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

Arteries of the Head and Neck

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...
