Abstract Objective We report a 11-month-old under immunized girl from the United States with ischemic stroke associated with inflammatory focal cerebral arteriopathy secondary to tuberculous meningitis. Methods Diagnosis was based upon the head CT, brain MRI, and magnetic resonance angiography (MRA) of the head and neck, CSF evaluation, TB blood and skin test, and gastric aspirate culture. Results Patient presented to the local emergency department (ED) for left arm and leg weakness. Laboratory work was significant for hyponatremia. Head CT demonstrated an area of attenuation in the right basal ganglia and caudate nucleus, and a focus of gray and white matter differentiation loss in the right frontal cortex. MRI brain showed a right middle cerebral artery stroke. CSF evaluation showed pleocytosis with hypoglycorrhachia and elevated protein. Further testing showed mediastinal and hilar lymphadenopathy and additional history included exposure to a grandparent with active tuberculosis. Discussion This case emphasizes the importance of childhood vaccinations and considering CSF evaluation, which is usually not considered as part of routine pediatric stroke work up. With increasing international travel and global immigration, clinicians even in the non-endemic countries should consider tuberculosis in their differential diagnosis.

Dear IPSO Virtual Conference Attendees:

Welcome to the IPSO 2023 Virtual Conference. We are delighted to bring together experts from multiple disciplines and six continents to provide a diverse perspective on pediatric cerebrovascular disease.

A few quick words about what to expect. Two important goals of this conference are to (1) foster a sense of community and (2) identify global priorities for our field. We encourage you to express your thoughts live in through the chat function to provide a global perspective on all topics. Please introduce yourself in the chat, so everyone knows where you are attending from.

We are excited to announce IPSO is able to offer 9.5 CME units for the virtual conference. If you would like to claim CME credits, please email membership@internationalpediatricstroke.org. 

We want to hear from you! Planning for IPSO 2024 Congress on March 22nd-24th in Toronto, Canada, will commence as soon as the Virtual Conference ends. Let us know your priorities through the live chat function, via email, or by submitting a symposium idea. Based on your input, the Scientific Program Committee will select the topics that we will address in greater depth when we meet again in the spring.

We hope you find the Virtual Conference both interesting and educational, and hope to see you in person in Toronto, or at another IPSO meeting in the future.

Warm regards,

Heather Fullerton, IPSO President 
Maja Steinlin, IPSO Vice-President
