The diagnosis and treatment of a patient with puerperal infection and subdural hygromas.

We describe a patient readmitted after developing a persistent postural headache resulting from an accidental lumbar puncture during labor 10 days earlier. Magnetic resonance imaging demonstrated bifrontal subdural hygromas and diffuse pachymeningeal enhancement. The patient had signs of a puerperal infection, and an epidural patch was performed with dextran 40 instead of blood, after which gradual improvement was noted.
