SALTR – a useful memonic to help remember the five types of growth plate fracture (Salter-Harris classification). Fortunately the order also directly relates to prognosis from best to worse.

  • S – slipped = type I
  • A – above = type II
  • L – lower = type III
  • T – through or transverse or together = type IV
  • R – ruined or rammed = type V

Scotty dog sign – refers to the normal appearance of the lumbar spine posterior elements when seen on oblique views:

  • the transverse process being the nose
  • the pedicle forming the eye
  • the inferior articular facet being the front leg
  • the superior articular facet representing the ear
  • the pars interarticularis (the lamina between the facets) equivalent to the neck.

If a spondylolysis is present, the pars interarticularis will have a defect and look like the Scotty dog has a collar – or doggy decapitation for those with a bloodier imagination!

Lobar haemorrhage – an intracerebral bleed (haemorrhagic stroke) that occurs superficially within the cerebral lobes. In contrast to hypertensive haemorrhages which occur deep within the brain, primary lobar haemorrhages occur superficially due to cerebral amyloid angiopathy. They typically occur in elderly patients and as with any haemorrhage, it is important to consider the possibility of an underlying tumour or vascular malformation.

MAGIC DR – a handy mnemonic used to remember the potential causes of a cerebral ring enhancing lesion.

M – Metastasis

A – Abscess

G – Glioblastoma multiforme

I – Infarct (subacute phase)

C – Contusion

D – Demyelinating disease (eg. tumefactive MS)

R – Radiation necrosis

An alternative is DR MAGIC of course, which is what you may like to call yourself if you can remember the list! Although you can’t possibly know by looking at the single images, for what it is worth, the above cases are; A = metastasis, B = abscess, C = radiation necrosis, D = GBM, E = demyelination, F = contusion.
