Clot does not require treatment? Normal?

Hi, Yesterday morning my uncle was having morning walk. While doing he slipped and he fell down on his face, it lead to severe blood loss, he was admitted to hospital. After having CT scan doctor told there is some minor clot developed but everything is fine and patient can be discharged in a day. Patient is feeling dizziness when sitting, but is fine when in sleeping position. but as per doctors its due to some tablets, and they now switched the tablets and told all will be fine. Now I'm bit confused clot is mentioned 4.8x1.8 cm, this dimension does not look minor or normal, we will be visiting neurologist for this anyway, after having MRI scan, but till then can this be explained if this is really normal? P. S:- attached lab report of CT scan by hiding lab and patient name.
