The co-occurrence of diverticulitis with pregnancy is incredibly rare and the management of recurrent complicated diverticulitis may not be feasible in a pregnant patient. Adding cases to the incredibly sparse literature may highlight similarities and create potential recommendations for at-risk populations. We present a case of a female at 18 weeks' gestation who presented with left lower quadrant pain. The initial physical exam and clinical findings revealed severe abdominal tenderness without signs of generalized peritonitis, leukocytosis with predominant neutrophils, and fundal height with confirmatory ultrasonography of intrauterine pregnancy. The main diagnosis was diverticulitis complicated by an abscess and pregnancy, confirmed with CT imaging. The initial intervention was IV antibiotics and bowel rest; however, with each subsequent discharge, she returned to the emergency department with worsening symptoms. Eventually, at 28 weeks, she was escalated to IV meropenem, CT-guided drainage of the abscess, and preterm vaginal delivery at 28 weeks, with a lower anterior resection and diverting ileostomy at six weeks postpartum. She is currently being followed outpatient with improvement in pain, meaningful healthy weight gain, and a healthy newborn child. While management of diverticulitis is generally straightforward, severe presentations like this, even when compared to existing literature, suggest traditional notions of contraindications and risks may not fully apply. Timing and management of recurrent diverticulitis in pregnancy necessitate further research to establish comprehensive guidelines tailored to these at-risk populations.
