Author(s): Menon Narayanankutty Sunilkumar


A sail-like, triangular projection from the mediastinum in chest radiographs is encountered in healthy children in the first few years of life. This has been proved to be the shadow of the thymus and is not of pathological significance. As it resembles a “sail” it is known as the thymic Sail Sign (SS). Literature review reported it is seen in about 10% of normal children. Interestingly many treating doctors are not aware about the significance of the SS and can be missed easily or not given proper importance. SS is also seen in conditions like pneumomediastinum (PNM), DiGeorge syndrome (DiGs) and others. The chance of SS conditions should be searched in every infant or children to achieve better outcome and to prevent complications. This case study report SS in an infant and highlight the SS with a review of literature.
