Subarachnoid hemorrhage (SAH) is bleeding into the subarachnoid space—the area between the arachnoid membrane and the pia mater surrounding the brain. Symptoms may include a severe headache of rapid onset, vomiting, decreased level of consciousness, fever, weakness, numbness, and sometimes seizures.

The provided image is a non-contrast CT scan of the brain showing significant abnormal findings. Most notably, there is hyperdense (bright white) material within the normally dark, fluid-filled subarachnoid spaces.
Hyperdense Basal Cisterns: Bright white material fills the central cisterns around the midbrain, creating a characteristic "star-shaped" pattern.
Sulcal and Fissural Involvement: Hyperdensity is visible extending into the Sylvian fissures bilaterally and the anterior interhemispheric fissure.
Asymmetry: There appears to be a larger, focal area of hyperdensity in the left posterior region compared to the right, which may indicate a primary source of bleeding or a localized clot.
Potential Considerations
The appearance is highly consistent with acute subarachnoid hemorrhage (SAH), where blood fills the spaces normally occupied by cerebrospinal fluid (CSF). This is often considered a medical emergency.
Differential possibilities for hyperdense areas on a brain CT include:
Aneurysmal Subarachnoid Hemorrhage: The most common non-traumatic cause, often due to a ruptured berry aneurysm.
Traumatic Subarachnoid Hemorrhage: Resulting from head injury, typically more localized near the site of impact but can be diffuse.
Hyperdense Neoplasms: Certain highly cellular or calcified tumors (e.g., lymphoma, medulloblastoma) can appear bright on CT.

The "berry aneurysm" in brain. An aneurysm is an abnormal bulge or ballooning in the wall of a blood vessel, most often an artery, caused by a weakening of the vessel wall. They can occur anywhere in the body but are commonly found in the aorta and arteries of the brain. While many aneurysms don't cause symptoms unless they are large enough to press on other structures, a rupture is a life-threatening medical emergency. The most common causes of aneurysms are chronic high blood pressure (hypertension) and atherosclerosis (plaque buildup in arteries), which together weaken arterial walls over time. Other significant contributing factors include smoking, family history (genetics), and certain connective tissue disorders like Marfan syndrome. Most brain aneurysms do not cause symptoms unless they rupture, so you might not know you have one without testing. The most common symptom of a ruptured aneurysm is a sudden and severe headache. Other symptoms may include nausea, vomiting, and a stiff neck.
