My 10 month old just got over a virus with fevers ranging from 101 to 103.5. He is presently not febrile but has developed a rash on arma , legs and abdomen. When chNGING HIS DIAPER I NOTICED A SLIGHT PORTRUSION UNDER HIS LEFT LOWER RIB. ANY CONCLUSIONS?
Protrusion under left lower rib could be spleen which has enlarged. I think it's not associated with the fever. Enlargement of spleen occurs in Thalassemia which is very common in India. Get an ultrasonography of abdomen done, if it reveals splenic enlargement get a HPLC done for thalassemia screen which is even recommended for every child. If you live in gala agar endemic area do a RK39 test also.
