Insights

Progressive encephalomyelitis with rigidity and myoclonus (PERM) can lead to serious iliopsoas hematomas. Early immunotherapy may resolve both neurological symptoms and these rare bleeding complications.

Area of Science:

  • Neurology
  • Hematology

Background:

  • Progressive encephalomyelitis with rigidity and myoclonus (PERM) is a rare neurological disorder.
  • Iliopsoas hematomas are serious bleeding complications, often seen in hemophilia or with anticoagulant use.

Observation:

  • This report details a rare case of PERM complicated by bilateral iliopsoas hematomas.
  • The patient presented with neurological symptoms characteristic of PERM and concurrent hematomas.

Findings:

  • Neurological symptoms of PERM improved significantly following immunotherapy.
  • The bilateral iliopsoas hematomas resolved after the immunotherapy treatment.

Implications:

  • This case highlights the potential for iliopsoas hematomas as a complication in PERM patients.
  • Neurologists should be vigilant for iliopsoas hematomas in patients diagnosed with PERM.
