Diagnosis:
Clinical features of neuropathy plus phosphate deficiency and exclusion of other causes
Clinical features:
Acute, Sensorimotor, areflexia, dysarthria
Phostphate levels: <2.4 mg/dl
Findings on investigations:
NCS/EMG:
- Demyelinating pattern (Prolonged distal latencies, reduced conduction velocities) [case report]
- In some cases axonal pattern [case reports]
- F-waves absent
- Decreased recruitment (neurogenic recruitment)
Pathology/Nerve biopsy:
Sub-perineural edema, mild axonal atrophy
Response to phosphate supplementation
Treatment:
Phosphate supplementation
