Task: CT Head (Stroke Evaluation)

Case Notes:

  • Patient: Mrs. Margaret Collins, 72 yrs, retired librarian

  • Referral source: Emergency Department

  • Presenting issues: Sudden right-sided weakness, slurred speech, onset 3 hrs ago

  • Associated symptoms: Difficulty swallowing, mild headache

  • Exam findings: GCS 15/15, right facial droop, reduced grip strength and leg movement on the right side

  • Medical history: Hypertension, atrial fibrillation (on warfarin), type 2 diabetes

  • Social history: Non-smoker, moderate alcohol, independent living

  • Request: Urgent non-contrast CT head to rule out acute intracranial hemorrhage before thrombolysis

To: Dr. Howard (Stroke Team Consultant)

Dear Dr. Howard,

I am writing to provide CT head findings for Mrs. Margaret Collins, a 72-year-old woman presenting with sudden right-sided weakness and slurred speech.

Non-contrast CT brain demonstrated no acute intracranial hemorrhage. There is early loss of grey–white differentiation within the left middle cerebral artery (MCA) territory, with subtle hypodensity involving the left basal ganglia, consistent with evolving acute infarction. No midline shift or mass effect is evident. The ventricles and basal cisterns are preserved.

Clinically, Mrs. Collins developed symptoms three hours ago, including dysarthria, dysphagia, and right hemiparesis. She has atrial fibrillation and hypertension, both of which increase her stroke risk.

The imaging supports an evolving ischaemic stroke within the left MCA distribution. As no hemorrhage is present, urgent consideration for thrombolytic therapy is advised, subject to clinical eligibility.

Yours sincerely,
[Radiographer’s Name]
