In patients with nontraumatic subarachnoid hemorrhage, the most frequent cause is the rupture of a saccular aneurysm. Non-contrast head computed tomography is the first choice for the diagnosis.

It is characteristically a monophasic illness that is commonly associated with a trigger event (e.g., febrile illness or vaccination). In cases of recurrent or multiphasic ADEM, the possibility of developing multiple sclerosis is of concern.

Management consists of supportive measures with symptom resolution in most cases; in more severe cases, therapeutic procedures to close the leaking defect are required.

Incorrectly Clipped/Coiled Aneurysms hemorrhage..Imaging follow-up is crucial after surgical or endovascular procedures to confirm aneurysm exclusion. Digital subtraction angiography remains the standard modality for evaluation of both coiled and clipped aneurysms. However, it is increasingly being replaced by noninvasive techniques such as CTA/MRA.
