It is very unlikely that your drusen are related to the lump on your head.
A number of conditions can cause lumps in the scalp or on the skull, the vast majority of which are benign in nature. Unfortunately, however, it is not possible to offer any specific diagnoses over the Internet. You should make an appointment with your physician for the specific purpose of having this lump evaluated.
Sincerely/ Robert A. Wascher, MD, FACS
