Use the MRI pattern, porphyria triggers, and inherited neuropathy genetics to orient the differential quickly. These are pattern-recognition problems where the imaging and trigger history matter most.
Key Takeaways
Hallervorden-Spatz disease is a rare inherited neurodegenerative disorder caused by abnormal iron accumulation in the basal ganglia; The eye-of-the-tiger sign is a classic MRI clue; Acute intermittent porphyria causes abdominal pain, psychiatric symptoms, neuropathy, and autonomic instability; Porphyria attacks can be triggered by barbiturates, phenytoin, sulfa drugs, or estrogen; HNPP is caused by PMP22 deletion
