Fat embolism in sickle-cell disease: A case report with literature review37 femalesLower back pain and bilateral shoulder painCT/CTA reports were normalLumbar punctureRed cell exchange transfusion[7]
PMID: 36741476Brain MRI showed a “starfield appearance” and incidental aneurysm in the supraclinoid portion of the right ICAPsychomotor slowness in long-term follow-up

Bone marrow necrosis and fat embolism syndrome in sickle cell disease during COVID-19 infection treated successfully with sequential red cell and plasma exchange35 malesGeneralized body aches, altered mental status, and feverBrain MRI showed multiple areas of restricted diffusion and microhemorrhages in a so‐called “starfield pattern”Lumbar puncture and bone marrow biopsyRed cell exchange transfusion and plasma cell exchange transfusion[8]
PMID: 36718354No complications

A suspected case of cerebral fat embolism triggering a drug-resistant status epilepticus in a HbS/β+-thalassaemia patient61 femalesSevere precordial chest pain and dyspneaBrain MRI showed widespread, nonconfluent areas of ischemia in multiple anterior and posterior vascular distributions with microhemorrhages consistent with a “starfield appearance” with a “walnut kernel microbleed” patternLumbar punctureRed cell exchange transfusion therapy[9]
PMID: 35444771No complications

Complete neurological recovery from fat embolism syndrome in sickle cell disease after sequential red cell exchange transfusion and therapeutic plasma exchange27 malesAltered mental statusBrain MRI showed multiple widespread microhemorrhages showing not only the characteristic “starfield” pattern but also a cytotoxic lesion of the corpus callosum, known to be the result of direct neurotoxicity by proinflammatory cytokinesNilRed cell exchange transfusion[10]
PMID: 34489185No complications

Bone marrow necrosis and fat embolism syndrome: a near-fatal complication in previously undiagnosed sickle beta + thalassemia37 malesFever, altered mental status, low back pain, unsteady gait, and urinary incontinenceBrain MRI showed evidence of subacute ischemia and chronic microhemorrhagesLumbar puncture and bone marrow biopsyRed cell exchange transfusion[11]
PMID: 33408108CT scan of the abdomen and pelvis showed moderate splenomegaly, hepatomegaly, cholelithiasis, and diffuse patchy sclerotic osseous abnormalitiesNo complications

Fat embolism syndrome in sickle cell β-thalassemia patient with osteonecrosis: an uncommon presentation in a young adult34 malesFever, hypoxia, encephalopathy, and generalized body achesBrain MRI with and without contrast revealed extensive punctate multifocal areas of diffusion restriction throughout the basal ganglia, thalami, and white matter of both hemispheres consistent with multifocal areas of punctate ischemic infarction in the acute to subacute stagesBM biopsyRed cell exchange transfusion[12]
PMID: 34008428Quinton catheter was placed for lifelong exchange transfusions every 4 to 6 weeks to keep hemoglobin S level to a goal of <30%No complications

Neurologic recovery in systemic nontraumatic fat embolism syndrome in an elderly patient with hemoglobin SC disease: a case report75 femalesChest pain and diffuse body achesBrain MRI showed extensive multiple microhemorrhages across the neuroparenchyma in a “starfield” pattern classic for cerebral FESNilRed cell exchange transfusion[13]
