CT brain
Right frontal craniotomy has been performed. Deep to this site, there is a focal region of high attenuation within the brain measuring approximately 9 mm in diameter. It is surrounded by ill-defined low attenuation. The appearances are those of focal haemorrhage at the site of prior biopsy. Post-operative pneumocephalus is also noted deep to the right frontal bone. A 2 cm focal region of ill-defined low attenuation is seen in the deep white matter of the left frontal lobe, corresponding to MRI changes at this site. The ventricular system is of normal size and is midline in location.
CT chest (not shown) and abdomen
Scans through the abdomen demonstrate left para-aortic lymphadenopathy measuring 2.4 centimetres transverse 1.7 centimetres AP and 5 cm craniocaudally. No further lymphadenopathy.
