  7. Headache  Characteristics  Pathology

  8. NICE Guidelines  Suspected Cancer: recognition and referral  NG12 updated July 2017  1.9 Brain and CNS  Headache  CG150 updated November 2015  Tension / Migraine / Cluster  Menstrual-related  Migraine with aura  Medication overuse

  9. Evaluate and Consider worsening headache with fever  headache triggered by cough, valsalva (trying to  breathe out with nose and mouth blocked) or sneeze sudden-onset headache reaching maximum intensity  within 5 minutes headache triggered by exercise  new-onset neurological deficit  orthostatic headache (headache that changes with  posture) new-onset cognitive dysfunction  symptoms suggestive of giant cell arteritis  change in personality  symptoms and signs of acute narrow angle glaucoma  impaired level of consciousness  a substantial change in the characteristics of their  headache. recent (typically within the past 3 months) head  trauma

  10. Consider compromised immunity, caused, for example, by HIV or immunosuppressive drugs  age under 20 years and a history of malignancy  a history of malignancy known to metastasise to the brain  vomiting without other obvious cause 

  11. Arachnoid Cyst

  12. Do not…  Do not refer people diagnosed with tension-type headache, migraine, cluster headache or medication overuse headache for neuroimaging solely for reassurance

  13. Calcified Meningioma

  14. 2ww  Consider an urgent direct access MRI scan of the brain (or CT scan if MRI is contraindicated) (to be performed within 2 weeks) to assess for brain or central nervous system cancer in adults with progressive, sub-acute loss of central neurological function

  15. Basal Ganglia Calcification

  16. Kernick, BJGP, 2008

  17. Vestribular Schwannoma

  18. Cerebral Aneurysm

  19. Anaplastic Astrocytoma

  20. Dementia subtypes  Alzheimer’s Disease  Fronto-Temporal Dementia  Behavioural  Language  Progressive Non-Fluent Aphasia  Semantic  Logopaenic  Lewy Body Disease  Vascular Dementia  Prion Disease

  21. AD or SD or FTD or HSE or RTA

  22. “Diagnosis of subtype of dementia should be made by healthcare professionals with expertise in differential diagnosis using international standardised criteria” Type Recommended diagnostic criteria 1 Prefer NINCDS/ADRDA criteria. Alzheimer's disease Alternatives include ICD-10 and DSM-IV. Prefer NINDS-AIREN criteria. Vascular dementia Alternatives include ICD-10 and DSM-IV. International Consensus criteria for Dementia with Lewy bodies (DLB) DLB. Lund – Manchester criteria, NINDS Frontotemporal dementia (FTD) criteria for FTD.

  23. Imaging in Dementia  Exclude other pathology  NOT needed  Establish subtype  Moderate / Severe Dementia  Diagnosis Clear  MRI vs CT  HMPAO SPECT  FTD vs AD vs VaD  DAT SPECT  DCLBD

  24. What is Vascular Dementia?  Multi-infarct  Atherosclerosis  Strategic Infarct  Small Vessel Disease  Subcortical  Cerebral Amyloid Angiopathy

  25. Parenchymal Haematoma

  26. What you tell us

  27. 40M persistent occipital headache several months- now daily

  28. Chronic Subdural Haematoma

  29. 24F worrying features of memory loss and word finding difficulties worse in last 6 months, now disabling as becoming reclusive as unable to hold conversations, bloods- normal, no headaches, no vomiting, well in self, ? SOL/ other intracranial pathology

  30. 37M head injury in rta 2m ago. Possibly mild concussion Cousin recently had brain tumour. No vom or neurology. Hx spondyloarthropathy. Daily headache since injury

  31. 55M 8m of daily episodes of deja vu with dread and witnessed vacant expresion and lip smacking. ?fit disorder. ?SoL

  32. Acute Subdural Haematoma

  33. 41M URGENT PLEASE. ?SOL. 4 day h/o left sided headache with intermittent right visual loss. Never had headaches before. Associated with nausea.

  34. 84F coronal views please. memory worsening over the past year. short term memory difficulty. hx of HTN. please to assess further. CT will be helpful with assessment of dementia type, leading medication options. many thanks

  35. 84F report  No focal mass lesion, haemorrhage or surface collection seen. There is moderate generalised involutional change with more focal atrophy affecting the temporal structures bilaterally.

  36. Pineal Calcification

  37. 55M dizziness and headache intermittently for 1-2 months. No pattern. Not positional. Feels nauseous. r/o SOL

  38. 81M URGENT: known dementia, but recent rapid decline. Has had falls. Less coordinated, harder to walk and follow instructions. More confused. ?subdural

  39. 81M report  No intracranial haemorrhage or collection. No evidence of recent infarction. There is extensive frontal, parietal and right medial temporal volume loss. The left medial temporal lobe is less severely affected. The imaging is compatible with a diagnosis of AD or FTLD.

  40. Cavernous Haemangioma

  41. 42F head injury oct 16 with concussion. heavy fence post fell onto her head. neck pain and headaches since then, much more acute headache now with some light sensitivity. No fundal changes but could she be scanned urgently?

  42. 69M getting regular focal migraines which hadn't had since he was 20

  43. 88F SOON PLEASE - many thanks Coronal views please Cognitive decline over this past year, hx of HTN. Also new intention tremor, is bilateral however. Reduced mobility over the past 2 months. No focal weakness. Hx of breast cancer. ? cause ? atypical dementia ? space occupying lesion ? other. with many thanks.

  44. 88F report No focal intraparenchymal mass lesion, haemorrhage or surface collection seen. Mild small vessel ischaemic change but with evidence of an old infarct in the region of the left globus pallidus. Moderate generalised involutional change with no particular focal atrophic element. There is an extra-axial calcified lesion on the left side of the foramen magnum likely to represent a small meningioma.
