Fat embolism in sickle cell disease.

Area of Science:

• Hematology
• Pulmonary Medicine
• Pathology

Background:

• Fat embolism is a recognized complication of sickle cell disease (SCD), particularly associated with marrow infarction.
• It presents a diagnostic challenge during sickle cell crisis, especially with respiratory compromise.

Purpose of the Study:

• To highlight the diagnostic features of fat embolism syndrome in sickle cell disease.
• To report a case where early diagnosis led to a successful outcome.

Main Methods:

• Clinical observation during sickle cell crisis with respiratory deterioration.
• Identification of fat globules in sputum.
• Demonstration of disseminated intravascular coagulation (DIC).
• Utilizing a double isotope technique to differentiate recent from old bone marrow infarction.

Main Results:

• The patient presented with symptoms suggestive of fat embolism during a sickle cell crisis.
• Diagnosis was confirmed antemortem by finding fat in sputum and evidence of DIC.
• A double isotope technique helped ascertain recent marrow infarction.

Conclusions:

• Fat embolism syndrome should be considered in sickle cell crisis patients with specific clinical and laboratory findings.
• Early and accurate diagnosis, aided by specific tests, is crucial for managing this potentially fatal complication and improving patient outcomes.
