Hair on end sign

Hair on end sign on X-ray skull is a typical finding seen in cases of chronic hemolysis. This sign is usually seen in cases of blood disorders like thalassaemia and sickle cell anemia. This condition results from the hyperplasia of bone marrow to compensate for the RBCs lost during the process of excessive hemolysis. Picture credit: https://radiologykey.com/bone-marrow-disorders/
