Introduction: Adrenal infarct is a rare cause of abdominal pain, which is especially true in pregnancy. The symptoms and signs of insufficiency will depend on the amount of adrenal function lost. The adrenal gland has a unique vasculature that may facilitate infarction in a hypercoagulable state. Currently only limited case reports and small series describing evaluation and management of adrenal infarct are found in the literature. Unilateral adrenal infarct is a rare finding in pregnancy but an important diagnosis to consider to prevent incorrect management and worsening bilateral infarction. Case Report: A 21-year-old G2P0010 presented at 29 4/7 weeks with sudden onset right upper quadrant and flank pain, fever, nausea, and vomiting. The patient was initially empirically treated for complicated urinary tract infection/pyelonephritis despite no clear laboratory evidence of infection. There was no evidence of adrenal insufficiency with the exception of fasting ketosis. The remainder of evaluation was unremarkable including ultrasounds and X-rays. Unilateral adrenal infarct was diagnosed on contrast-enhanced computed tomography with no associated hemorrhage.Thrombophilia assessment was notable for methylenetetrahydrofolate reductase (MTHFR) gene heterozygous and prothrombin G20210A gene heterozygous.
