Hard to say: When these are simple fluid collections they usually fade in a few days. There are times when a blood vessel crossing between the scalp & skull breaks it will produce such a feature that can take weeks to fade. There is no circulation in that space (skull to scalp) so a blood accumulation must dissolve & gradually fade over weeks to months. An exam could confirm/exclude this.
