Big Bump Appeared On Head After Head Injury. Could It Be A Brain Tumour?
Welcome to XXXXXXX
First i would like to assure you that it is extremely unlikely to be a cancer-
a. as cancers occurring in the brain do not project outside - due to the hard skull bone and
b. malignant bone tumors of the skull bone are very rare.
It is probably a scalp lesion.
Probabilities are---
1. Dermoid cysts.
2. Sebaceous cysts ( epidermoid cysts)
3. Other rare causes like infected follicle etc- in which case there will be pain and fever.
The first two are the most common based on your description.
Dermoid cyts occur in the midline usually and sebaceous cysts can occur anywhere.
The most important thing here is to get a radiograph or a CT done - after physical examination to check for extension inside the bone, which your doc will be aware of.
Pls. get medical advice for re- assurance.
Regards
DR GS
