Associated symptoms include fever, headache, difficulty breathing, and back pain. Because resources in sub-Saharan Africa are limited, access to comprehensive care for patients with SCD is variable. The general principles of management focus on early diagnosis, parental education, prevention of infection with vaccinations and prophylactic medications, prompt treatment of infection and pain, the use of hydroxyurea for stroke prevention, and blood transfusions for life-threatening anemia. This patient has a known diagnosis of SCD but has infrequent pain episodes and no previous transfusions. He is not receiving hydroxyurea or prophylaxis against bacterial infections or malaria. He has no history of stroke and no known head trauma. On presentation he is afebrile and his heart rate is 120 beats/min, respiratory rate is 40 breaths/min, and blood pressure is 105/75 mm Hg. His oxygen saturation is 92% in room air. Physical examination is significant for pallor, periorbital edema, scalp edema, dyspnea without adventitious lung sounds, and splenomegaly with diffuse abdominal tenderness. His scalp edema is fluctuant and extends posteriorly from the periorbital region, encompassing the entire scalp. Swelling is most prominent in the frontal and parietal areas. The overlying skin is nonerythematous and nontender but is warm to the touch. His neurologic examination has no focal findings, although generally he appears tired. Initial laboratory results demonstrate a white blood cell count of 84,000/μL (84×109/L) with a lymphocytic predominance (57%), a hemoglobin level of …
