These sound like some sort of maggot and it sounds as if it should be treated quite urgently
Hi
Welcome to the MedHelp forum
In all probability your mother has subcutaneous cysticercosis or a neuro cysticercosis which released the cyst contents on the scalp. This is caused by tape worms. Other than that it could also be a normal cyst infected with maggots. Let the reports come back for final diagnosis. Please let me know if there is any thing else and do keep me posted. Take care!
