Notably, her prenatal course was marked by normal blood pressure and 3 negative urine protein tests.<h4>Diagnoses</h4>The patient was diagnosed with incomplete HELLP syndrome and a ruptured SLH. This intraoperative diagnosis was confirmed by the identification of 800 mL of noncoagulated blood and a 4 × 2 cm left hepatic lobe subcapsular hematoma with sMedicinee44186https://www.ebi.ac.uk/biostudies/studies/S-EPMC12401199biostudies-literatureIntraoperatively diagnosed spontaneous rupture of a subcapsular liver hematoma with incomplete hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome: A case report and literature review.PMC12401199Li XXia ZJiang XKang YChen DfalseIntraoperatively diagnosed spontaneous rupture of a subcapsular liver hematoma with incomplete hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome: A case report and literature review.<h4>Rationale</h4>Subcapsular liver hematoma (SLH) during pregnancy is a rare but potentially life-threatening complication, often associated with hypertensive disorders such as preeclampsia and hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome.<h4>Patient concerns</h4>We report the case of a 37-year-old primipara who presented at 39 weeks of gestation with severe preeclampsia (blood pressure, 166/106 mm Hg; proteinuria, 2+).
