These aneurysms arise at weak points in the arterial wall, usually at branch points of the circle of Willis, making them highly relevant for USMLE Step 1 and Step 2 CK. We begin by reviewing the most common sites, including the anterior communicating artery, posterior communicating artery, and middle cerebral artery bifurcation. The pathogenesis involves congenital defects in the tunica media and elastin, often worsened by risk factors such as hypertension, smoking, autosomal dominant polycystic kidney disease (ADPKD), and connective tissue disorders like Ehlers–Danlos syndrome. Clinical symptoms may range from being asymptomatic to warning headaches (“worst headache of life” in subarachnoid hemorrhage), cranial nerve palsies (especially third nerve palsy with posterior communicating artery aneurysm), visual field defects, or sudden collapse due to rupture. Diagnosis is typically made with CT scan of the head, which detects subarachnoid hemorrhage, followed by CT angiography or MR angiography to localize the aneurysm. Lumbar puncture showing xanthochromia is confirmatory when CT is negative but suspicion remains high. Pathology reveals thin-walled outpouchings lacking a muscular layer and internal elastic lamina, predisposing them to rupture. Histologically, they are not true aneurysms but acquired lesions at congenital weak spots. Clinically, management includes blood pressure control, neurosurgical clipping, or endovascular coiling to prevent re-bleeding, along with monitoring for complications such as vasospasm, hydrocephalus, and re-rupture. By combining vascular anatomy, pathology, clinical features, diagnostic imaging, and management strategies, this lecture equips medical students, residents, and healthcare professionals with exam-ready insights for Step 1 and Step 2 CK and practical relevance in neurology and neurosurgery. #BerryAneurysm #SaccularAneurysm #SubarachnoidHemorrhage #USMLEStep1 #USMLEStep2CK #CircleOfWillis #ClinicalNeuroanatomy #NeuroPathology #IntracranialAneurysm #USMLEPreparation #MedicalStudentsUSA #DoctorEducation #MedicalEducationUSA #Step1Prep #Step2CKPrep #USMLEVideos #NeurologyEducation #berryaneurysm #berryaneurysmpathology #berryaneurysmlecture #berryaneurysmvideo #berryaneurysmanimation #berryaneurysmusmle
