Comparison made to the previous CT scans.
The haematoma in the left anterior frontal lobe has a peripherally enhancing rim and measures 3 x 3 cm in axial dimension and a second haematoma in the posterior frontal lobe also enhances peripherally measuring 3 x 2.5 cm. There is a third subtle peripherally enhancing lesion in the inferomedial left frontal lobe measuring
1 x 1 cm and a 1cm lesion in the inferomedial right frontal lobe with equivocal enhancement. There is also increasing gyral enhancement through the left frontal and temporal lobe and increasing adjacent white matter oedema. Mild effacement of the left lateral ventricle with 4mm midline shift to the right.
Left frontal craniotomy. A small underlying collection measures up to 3mm in depth. There are also bifrontal low density subdural collections measuring up to 8mm on the left and 5mm on the right with no convincing enhancement.
Extensive mucosal thickening and fluid and fluid throughout the mastoid air cells.
CONCLUSION:
Three peripherally enhancing lesions in the left frontal lobe in clinical setting are worrisome for infection with secondary abscess formation.
