Lumbar plexus neuropathy resulting from retroperitoneal hemorrhage

Area of Science:

• Neurology
• Radiology
• Pharmacology

Background:

• Lumbar plexus neuropathy is a rare complication.
• Heparin is an anticoagulant medication.
• Retroperitoneal hematomas can lead to neuropathy.

Observation:

• A case of lumbar plexus neuropathy during heparin therapy is presented.
• CT scan identified a retroperitoneal hematoma before full neuropathy symptoms appeared.
• The hematoma originated within the psoas muscle.

Findings:

• Two distinct patterns of retroperitoneal bleeding and their clinical presentations are discussed.
• Psoas muscle hematoma is a potential cause of lumbar plexus neuropathy.
• Neurologic compromise can result from expanding hematomas.

Implications:

• Early detection of retroperitoneal bleeding via CT imaging is vital.
• Prompt diagnosis allows for timely intervention to prevent irreversible nerve damage.
• Understanding these syndromes improves patient outcomes in anticoagulated patients.
