[Coexistence of a disc herniation and psoas hematoma revealed by L3 deficiency].

Radiculopathy is a constellation of symptoms secondary to a pathology affecting the nerve root, the most frequent cause of which is a herniated intervertebral disc. We report a case of a 58-year-old man under anticoagulant admitted to the neurosurgery department of Lariboisière hospital (Paris) for an L3 motor deficit that occurred progressively over a period of 24 hours with an L3-L4 disc herniation on the MRI. However, a psoas hematoma was also noted. Biological assessments revealed a hemostasis disorder. The final clinical diagnosis was a spontaneous hematoma caused by anticoagulant overdose. Psoas hematomas usually occur in patients with coagulopathy.
