Practice cases to go with the second CT brain lecture, with cases relating to hydrocephalus and reviewing haemorrhage

1. HEAD CT CASES 2

2. Diagnosis: Small left basal ganglia bleed. Minimal mass effect. Likely hypertensive.
Posterior spinal line

3. Diagnosis: Right subdural. Extensive midline shift.
Posterior spinal line

4. Posterior spinal line
Diagnosis: Left peripheral subarachnoid haemorrhage. No mass effect. Likely traumatic.

5. Posterior spinal line
Diagnosis: Central subarachnoid haemorrhage. Likely aneurysm rupture. Hydrocephalus.

6. Posterior spinal line
Diagnosis: Right extradural haemorrhage. Midline shift. Right occipital infarct.

7. Posterior spinal line
Diagnosis: Bifrontal extradural haemorrhage.

8. Posterior spinal line
Diagnosis: Right sided extradural haemorrhage. Not biconvex, but is bounded by sutures.

9. Diagnosis: Subacute right subdural haemorrhage.

10. Diagnosis: Left intra-axial haemorrhage and right subdural haemorrhage. Likely traumatic.

11. Diagnosis: Left subdural haemorrhage along the skull vault and along the tentorium.

12. Diagnosis: Central (aneurysmal) subarachnoid haemorrhage. Hydrocephalus of the temporal horns.

13. Diagnosis: Hydrocephalus. Ventricles much more prominent than sulci.

14. Diagnosis: Mass obstructing left foramen of Munroe, with left lateral ventricle hydrocephalus.

15. Diagnosis: Atrophic changes. Ventricles and sulci both enlarged.
