Investigations and work-up
Based on the clinical examination, a computerized tomography (CT) scan
of the head and two dimensional echocardiography were requested. In
addition, a blood sample was withdrawn and sent to the lab for
estimation of hemoglobin, platelet count, electrolytes, urea,
creatinine, and coagulation profile testing. CT scan showed an infarct
in the left middle cerebral artery territory (Figure 1 to Figure 3), and
echocardiography showed normal ventricular function. Similarly, all
requested lab parameters were in the normal range, including coagulation
parameters (prothrombin time, international normalized ratio, activated
partial thromboplastin time, and prothrombin time index).
