The image that appears on the CT scan gives suggestions of the type of injury, but to be sure it is necessary remove the lesion or part of it to make an examination of the tissue itself.
Only then will it be possible to know if it is an eosinophilic granuloma, dermoid or epidermoid cyst or metastasis, but for this it is necessary to open the skull.
O eosinophilic granuloma is a benign lesion that cures spontaneously. However, treatment is often necessary due to the pain, swelling and aggressiveness of the lesion, which grows progressively.
The dermoid cysts in the skull are rare and usually appear around 22 years of age. Although it grows extremely slowly, its contents may leak and cause chemical meningitis.
Surgical treatment may be necessary to remove the dermoid cyst. If not completely removed, the cyst tends to arise again.
The epidermoid cysts are more common than dermoids. In most cases the cyst is detected between 50 and 60 years.
If they are not completely removed they also tend to return and rarely cancer (carcinoma).
The diagnosis can only be made by the doctor neurologist or neurosurgeon.
