Serious neurologic complications from coronavirus disease 2019 (COVID-19) vaccination are rare, and only a few cases of Guillain-Barré syndrome (GBS) have been reported after COVID-19 vaccination. We present the first reported case of the facial diplegia variant of GBS after recent COVID-19 vaccination in a pregnant woman. The 30-year-old patient was 27 weeks pregnant at the time she was diagnosed with the facial diplegia variant of GBS. Her symptoms began two weeks after she received the Ad26.COV2.S COVID-19 vaccine. A thorough evaluation for GBS was done, including a lumbar puncture that demonstrated elevated cerebrospinal fluid (CSF) protein and nerve conduction study (NCS) that found evidence of a diffuse sensorimotor demyelinating polyneuropathy. Nasal swab testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was negative on two occasions five days apart. All other diagnostic testing was unremarkable or nonexplanatory of the patient’s clinical presentation. She was started on intravenous immunoglobulin (IVIG) and had significantly improved dysphasia, dysarthria, and facial strength. The patient recovered to baseline four weeks after presentation.
