I have had a lump on my head for a couple of years, it formed on my head after a stone wear loaf pan fell out of a cabinet and hit my head, recently I noticed it was a little bigger, it is soft but almost feels like it s filled with fluid or it feels similar to a lipoma, today I as poetically poked it with a needle and it started leaking clear non odorous fluid, it shrunk a bit, as I palpated the area I can feel a hold in my skull which the bump has covered up, it s a hole the size of a fingertip. Is it possible it was CSF leaking and I have a serious problem?
Hi, thanks for sharing your health concerns with Chat Doctor!  If I were your treating Doctor for this case of a head lump, I would come up with only one and one possibility that is a sebaceous cyst! Nothing to worry about this and try not to get infected there! Well, this is a fairly common benign disease of the skin/skin appendages and CSF has nothing to do with it; however, in worse case it could be some parasitic cyst also! I suggest you to go for an FNAC test of the lump for confirmation and to relieve your concerns! Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
