Match each clinical presentation of postpartum febrile morbidity to its most likely underlying diagnosis based on the timing and specific physical exam findings.
- A 28-year-old patient develops fever, malodorous lochia, and marked uterine fundal tenderness 48 hours after a cesarean delivery for arrest of descent.Postpartum endometritis
- A 25-year-old exclusively breastfeeding patient develops bilateral breast swelling, warmth, tenderness, and a low-grade temperature of 37.9°C (100.2°F) 72 hours after an uncomplicated vaginal delivery.Breast engorgement
- A 31-year-old patient presents with high fever, myalgias, and focal, unilateral breast erythema and induration on postpartum day 18.Lactational mastitis
- A 34-year-old patient continues to experience spiking fevers on postpartum day 6 despite 72 hours of intravenous clindamycin and gentamicin; her abdomen and pelvis are non-tender on examination.Septic pelvic thrombophlebitis
Answer
The correct pairings match postpartum endometritis to the presentation with uterine tenderness and malodorous lochia; breast engorgement to early, bilateral breast symptoms; lactational mastitis to delayed, unilateral focal breast erythema; and septic pelvic thrombophlebitis to persistent fever unresponsive to antibiotics with a normal pelvic exam.
Correctly diagnosing postpartum fever requires integrating the mode of delivery, postpartum day, and clinical findings. Endometritis is the most common cause of puerperal fever, typically occurring days 2-3 post-cesarean with uterine tenderness. Breast engorgement is a bilateral, physiologic process occurring 2-4 days postpartum. Mastitis presents later (weeks 2-4) as a unilateral, focal infection. Septic pelvic thrombophlebitis is a diagnosis of exclusion characterized by relapsing fevers unresponsive to appropriate endometritis therapy.

Key Concept
Differentiation of postpartum febrile morbidity relies on analyzing the timeline of symptom onset and localizing specific physical exam findings.
