Sickle cell disease may manifest with cerebrovascular and systemic complications. Sickle crisis that results in avascular necrosis of long bones with resultant cerebral fat embolism syndrome is rare and has a characteristic “starfield” pattern on MRI. This “starfield” MRI pattern should raise suspicion for sickle cell crisis in patients without a known history of the disease, which can lead to earlier sickle cell red blood cell exchange transfusion and treatment. We present a case of a male who presented emergently with acute seizure, coma with a characteristic MRI pattern, which lead to the diagnosis of avascular bone marrow necrosis and cerebral fat embolism syndrome from sickle cell crisis
