  Introduction: A Clinical Story That Begins with Subtle Clues A 14-year-old patient presents with chronic fatigue, pallor, and mild facial bone deformities. Initial laboratory findings suggest anemia, but the severity appears disproportionate. A chest X-ray reveals rib expansion, and a subsequent CT scan diagnosis demonstrates classic marrow hyperplasia. What initially seemed like routine anemia evolves into a textbook case of Beta-thalassemia —a genetic hematologic disorder with profound systemic and radiologic implications. In today’s era of medical imaging AI , early detection and precise radiology interpretation are transforming outcomes. This article provides a comprehensive, high-authority exploration of Beta-thalassemia, integrating clinical medicine with CT scan diagnosis , trauma imaging principles , and emergency diagnosis workflows . Understanding Beta-Thalassemia Pathophysiology: The Molecular Basis Beta-thalassemia is a hereditary blood disorder caused by mut...

It is a hallmark of several inherited and acquired disorders, including β-thalassemia. This article provides a comprehensive discussion of marrow hyperplasia from pathophysiological mechanisms to radiological interpretation, diagnostic differentials, and management, illustrated through a clinical case of a 39-year-old woman with β-thalassemia major. This discussion integrates the latest literature and aims to serve as a concise yet authoritative review for clinicians, radiologists, and medical examinees. 1. Case Summary A 39-year-old woman with β-thalassemia major has required monthly red blood cell transfusio...
