Sumario:Reversible cerebral vasoconstriction syndrome (RCVS) manifests with a thunderclap headache and reversible vascular abnormalities. Red blood cell transfusions have not been well identified as a risk factor for RCVS. We report a rare case of acute brain injury resulting from RCVS after a packed red blood cell (PRBC) transfusion. A 49-year-old female with a history of menorrhagia initially presented with generalized weakness. She was found to have a hemoglobin (Hgb) of 1.7 g/dL in the setting of a fundal fibroid for which she received five units of PRBCs. Post transfusion, she complained of several days of thunderclap headache and later returned with new-onset seizures. She was admitted to the neurocritical care unit for the treatment of status epilepticus. Metabolic, infectious and toxic work-up were unremarkable except for an elevated lactate. MRI of the brain with contrast showed extensive bilateral hemispheric and cerebellar white matter T2-weighted fluid-attenuated inversion recovery (T2/FLAIR) hyperintensities with areas of enhancement. A diagnostic cerebral angiogram was performed to evaluate for a vascular etiology and revealed focal segmental stenoses in bilateral A1 segments of the anterior cerebral arteries and in branches of the bilateral middle cerebral arteries. These findings were suggestive of RCVS. Clinicians should have a high degree of suspicion for RCVS in patients presenting with neurological manifestations, such as thunderclap headache or seizures after recent transfusion. The window for injury may be longer than that seen in other organs, such as in transfusion-related acute lung injury (TRALI).
