History and Physical — Patient 5

History

The patient is a 32 year old right-handed male with a previous admission three months prior to this hospitalization. At that time, he presented with a right frontal headache, a mild left facial droop, and left hemiparesis with the arm more affected than the leg. A CT scan of the head without contrast was done approximately 10 hours after the initial symptoms.

A MRI of the brain with and without contrast and a MRA was performed three days following admission. Blood cultures, urine toxicology screens, and laboratory stroke profile tests were normal. A lumbar puncture revealed a WBC of 31 with a differential of 6% neutrophils, 82% lymphocytes, and 11% monocytes; RBC 10; protein 27; glucose 67; and all CSF cultures negative. The patient's hemiparesis improved and he was placed on medication and discharged to home with plans for follow-up in the clinic.

He described his headache as bilateral, throbbing, and localized to the temporal regions. This headache was graded as 7/10 and had been present for approximately 10 hours.
