CT
Non-displaced nasal bone fracture on right. Soft tissue contusion over left zygoma.
Right occipital intra-axial elliptical lesion with target appearance, isodense to adjacent white matter and measuring 14 mm across, with profuse perifocal edema. Larger lesion in left cerebellar hemisphere with similar appearance, measuring 23 mm across, with perifocal edema involving the vermis and left middle cerebellar peduncle and distorting the fourth ventricle.
Sulcal and ventricular width appropriate for age; basal cisterns mildly dilated.
Small left parasagittal lacunar pontine infarct, probably chronic.
Impression:
The intracranial lesions most probably represent metastases; however, taking patient history of drug abuse into consideration, abscesses cannot be ruled out entirely.
