For suspected ischemic stroke in pregnancy, which diagnostic step is typically considered first?

• A. CT or MRI brain imaging
• B. Immediate surgical thrombectomy without imaging
• C. Lumbar puncture as first test
• D. Delay imaging until postpartum

Answer: (A)

Rapid brain imaging is essential because the immediate goal is to determine whether the brain injury is ischemic or hemorrhagic and to identify its location, which directly guides treatment decisions. In pregnancy, a CT head with fetal shielding or an MRI brain is typically the first diagnostic step because it provides fast, critical information about bleeding vs clot and helps decide eligibility for reperfusion therapies. Jumping straight to thrombectomy without imaging would be inappropriate, since you must confirm the pathology and anatomy before proceeding. Lumbar puncture as the initial test doesn’t address the acute presentation and won’t guide urgent management, and delaying imaging until after delivery puts the mother at unnecessary risk and misses the treatment window.
