In USMLE Step 1, it's essential to understand both the classification and pathophysiology of aneurysms as they integrate pathology, anatomy, and vascular medicine. Aneurysms are broadly classified as true or false, and morphologically as fusiform or saccular. A true aneurysm involves all three layers of the arterial wall — intima, media, and adventitia — and results from chronic pressure-related degeneration (commonly seen in abdominal aortic aneurysms). In contrast, a false aneurysm or pseudoaneurysm does not involve all three layers; instead, blood leaks out of the vessel and is contained by surrounding tissues, often following trauma or iatrogenic injury (such as post-catheterization). Morphologically, a fusiform aneurysm is a spindle-shaped, symmetrical dilation involving the entire circumference of the vessel — commonly seen in abdominal and thoracic aortas. A saccular aneurysm, on the other hand, appears as a pouch-like, localized outpouching involving only a portion of the vessel wall — frequently observed in cerebral (berry) aneurysms. The risk of rupture correlates with the size, growth rate, and location of the aneurysm. Clinically, aneurysms may be asymptomatic or may present with mass effect, ischemia, or catastrophic rupture. Imaging modalities like ultrasound, CT angiography, and MRI are crucial for diagnosis and planning. For Step 1, students should focus on the differences in wall involvement, typical locations, morphology, causes, and complications of each aneurysm type, along with recognizing buzzwords in MCQs such as "pulsatile mass," "contained hematoma," or "berry aneurysm in circle of Willis." #Aneurysm #TrueVsFalseAneurysm #SaccularAneurysm #FusiformAneurysm #USMLEStep1 #USMLEPathology #Step1HighYield #DrGBhanuPrakash #MedStudentReview #MedicalEducation #VascularPathology #NeuroAneurysm #Pseudoaneurysm #BerryAneurysm #MCQReview #USMLEIndia #Step1Concepts #MedSchoolReview #PathologyBuzzwords #HighYieldMedicine #CTAngiography #UltrasoundImaging #Step1Ready #WhiteboardMedicine #InternalMedicine #EmergencyMedicine #CardiovascularPathology #SurgeryPrep #AorticAneurysm
