Abstract
A 39-year-old female secondipara patient had an acute otitis media 15 days prior to her third delivery without complications. On the 7th day of puerperal period, she became unconscious and was taken to the hospital. Cerebrospinal fluid showed polynuclear pleocytosis and glucose level at zero. Hydrocephalus and bilateral thalamic infarction were seen on MRI, and cerebral venous thrombosis on MRV. Streptococcus pneumoniae was cultured both from cerebrospinal fluid and blood. The diagnosis of septic dural sinus thrombosis was made. She was treated without surgical intervention, and instead with antibiotics and heparin. The condition was dramatically improved and the expansion of thalamic infarction was prevented. Her consciousness disturbance was improved and she was able to eat and talk before discharge.
