Pelvic Fluid Collection Post Vaginal Delivery Treated with Ultrasonic Aspiration: A Case Report.

Background Pelvic fluid collection can complicate a variety of abdominal surgeries and gynecological inflammations; nevertheless, it is considered a rare pathological consequence after normal vaginal delivery. It is characterized by a wall of thick fibrous tissue that delineate an area of pus and necrotic tissues. Case presentation A 31-year-old Saudi female presented with lower abdominal pain and dysuria 7 days following normal vaginal delivery. Apart from mild lower abdominal tenderness; the physical examination has been otherwise clear. The work-up showed leukocytosis and a high CRP level. The mild pelvic collection was shown on abdominal ultrasonography and the CT scan of the abdomen revealed an enhanced wall pelvic fluid collection measure of about 13*3.3 cm. The patient received injectable antibiotics, and the fluid was aspirated initially, via a transvaginal route under ultrasound guidance. Days later, further fluid was aspirated with the placement of a catheter inside. Conclusion Physicians and obstetricians should have a high rate of suspicion for diagnosing Pelvic fluid collection. Injectable antibiotics and fluid aspiration with or without catheter placement are the mainstays for treatment.
