Stippled Epiphyses Differential Diagnosis

Today's Daily Diff is about stippled epiphyses. In these cases, the epiphyses appear to have multiple, small, round densities within them. If you have a hard time remembering the diverse causes, don't worry - just take a WHACK at it:

  • maternal use during pregnancy
Hans Zellweger syndrome

  • Hypothyroidism / cretinism is a much more common cause
  • Hans Zellweger aka cerebro-hepato-renal syndrome
  • rare leukodystrophy
  • punctata in patella
  • maternal use during pregnancy
CChondrodysplasia punctata congenita
  • multiple variants exist (ex: Conradi–H√ľnermann syndrome)
  • causes growth problems
Kvitamin K deficiencies
  • Vitamin K reductase deficiency
  • ex: Warfarin use

Admittedly, the mnemonic is a bit of a stretch, but essentially the diagnoses are either due to syndromes or factors that affect vitamin K metabolism.
