A 33-year-old pregnant woman was hospitalised with fever, cough, myalgia and dyspnoea at 23.5 weeks of gestation (WG). Development of acute respiratory distress syndrome (ARDS) mandated invasive mechanical ventilation. A nasopharyngeal swab proved positive for severe acute respiratory syndrome coronavirus 2 by reverse transcription-PCR. The patient developed hypertension and biological disorders suggesting pre-eclampsia and HELLP (haemolysis, elevated liver enzyme levels and low platelet levels) syndrome. Pre-eclampsia was subsequently ruled out by a low ratio of serum soluble fms-like tyrosine kinase-1 to placental growth factor. Given the severity of ARDS, delivery by caesarean section was contemplated. Because the ratio was normal and the patient's respiratory condition stabilised, delivery was postponed. She recovered after 10 days of mechanical ventilation. She spontaneously delivered a healthy boy at 33.4 WG. Clinical and laboratory manifestations of COVID-19 infection can mimic HELLP syndrome. Fetal extraction should not be systematic in the absence of fetal distress or intractable maternal disease. Successful evolution was the result of a multidisciplinary teamwork.
