Overview

Hypocalcemia must be differentiated from tetanus, Neuroleptic Malignant Syndrome, Viral Meningitis, Stiff man syndrome, Strychnine poisoning and Parkinson's disease.

Differential Diagnosis

One the basis of stiffness and fever it can be differentiated from:

Differential Diagnosis of Tetanus
Disease Diagnosis Treatment
Symptoms Signs Laboratory Findings
Tetanus[1][2]
  • Not significant
Neuroleptic Malignant Syndrome [3][4]
Viral Meningitis[5][6][7]
Stiff man syndrome
  • Marked rigidity
  • Spasms
    • Intermittent
    • Painful
    • Absent during sleep
Drug induced (Tardive dyskinesia)[8][9][10]
  • History of intake of the offending drug for at least one month
  • Eye deviation
  • Head and neck jerky movements
  • No tonic contraction of the muscles between the spasms
Strychnine poisoning[11][12][13][14]
  • Hx of up to date tetanus immunizations
  • History of intentional or accidental intake
    • Strychnos nux vomica seeds
    • Rodenticide
  • Hypervigilance
  • Anxiety
  • Mydriasis
  • Hypereflexia
  • Clonus
  • Facial and neck stiffness
  • Blood assay
  • Tissue assay
  • Urine assay
  • Initial stabilization
  • High dose Benzodiazepines
  • Intubation and airway securing
Hypocalcaemia[15][16]
Parkinson's disease[17][18]
  • Clinical diagnosis
  • Improvement with dopaminergic therapy confirms diagnosis
