The Friday Case Challenge includes difficult-to-diagnose conditions, some of which are not frequently encountered by most clinicians, but are nonetheless important to accurately recognize. Test your diagnostic and treatment skills using the following patient scenario and corresponding questions. Disclaimer: The following case is fiction and for educational purposes only.

A 32-year-old woman presents to the emergency department with a three-day history of worsening lower abdominal pain, fever, and vaginal discharge. She reports a previous diagnosis of pelvic inflammatory disease (PID) that was treated with oral antibiotics a month ago. The patient admits to inconsistent condom use and multiple sexual partners.
On examination, she appears uncomfortable and is febrile with a temperature of 101.5°F (38.6°C). Abdominal palpation reveals tenderness in the bilateral lower quadrants, with guarding and rebound tenderness. Pelvic examination demonstrates cervical motion tenderness, and there is purulent discharge noted on speculum examination.
Laboratory studies reveal an elevated white blood cell count (14,500/mm³) with a left shift. A urine pregnancy test is negative. Transvaginal ultrasound is performed, revealing a complex adnexal mass with thick septations and fluid collection. The ovaries appear enlarged and surrounded by echogenic material.
1.What is the most likely diagnosis?
A) Ectopic pregnancy

C) Tuboovarian abscess
D) Endometriosis
2. Which of the following is the initial treatment of choice for this condition?
A) Intravenous antibiotics
B) Laparoscopic drainage
C) Hysterectomy
D) Ovarian cystectomy
3. What long-term complication should be monitored in a patient with a history of this condition, especially if fertility preservation was a priority during treatment?
A) Ovarian cyst formation
B) Recurrent pelvic inflammatory disease (PID)
C) Chronic pelvic pain
D) Ectopic pregnancy
4. In addition to antibiotics, what other therapeutic approach may be considered in managing this condition?
A) Hysterectomy
B) Oophorectomy
C) Percutaneous drainage
D) Uterine artery embolization
Answer 1:
C) Tuboovarian abscess
Explanation 1:
Given the patient’s history of PID, lower abdominal pain, pelvic tenderness, and a palpable mass, the most likely diagnosis is a tuboovarian abscess. This condition is characterized by the formation of an abscess involving the fallopian tubes and ovaries, often as a complication of untreated or inadequately treated pelvic inflammatory disease.
Incorrect Answer A) Ectopic pregnancy:
Ectopic pregnancies may cause lower abdominal pain, but the palpable mass seen in this scenario is more indicative of an inflammatory process like a tuboovarian abscess. Ectopic pregnancies typically present with adnexal masses but are not associated with a history of pelvic inflammatory disease (PID).
Incorrect Answer B) Ovarian cyst:
While ovarian cysts can cause lower abdominal pain, the palpable mass, along with a history of PID, suggests a more acute inflammatory process like a tuboovarian abscess. Ovarian cysts, in general, may not present with palpable masses unless they are large or complicated.
Incorrect Answer D) Endometriosis:
Endometriosis can cause pelvic pain but usually doesn’t present with a palpable mass. The palpable mass, along with adnexal tenderness and a history of PID, points more towards an acute inflammatory condition like a tuboovarian abscess.
Answer 2:
A) Intravenous antibiotics
Explanation 2:
The initial treatment for a tuboovarian abscess involves intravenous antibiotics to cover the likely infectious organisms. Broad-spectrum antibiotics that cover both aerobic and anaerobic bacteria are typically used.
Incorrect Answer B) Laparoscopic drainage:
Laparoscopic drainage is not the initial treatment for a tuboovarian abscess. This invasive procedure is usually reserved for cases where there is a failure to respond to antibiotic therapy, or if there is a need to drain a large, complex abscess.
Incorrect Answer C) Hysterectomy:
Hysterectomy, the surgical removal of the uterus, is not the initial treatment for a tuboovarian abscess. This drastic measure is generally reserved for severe cases or when there is a significant risk of complications. Preserving fertility is a key consideration, especially in younger patients.
Incorrect Answer D) Ovarian cystectomy:
Ovarian cystectomy, the surgical removal of an ovarian cyst, is not the primary treatment for a tuboovarian abscess. The abscess involves both the fallopian tubes and ovaries and is usually managed with antibiotics initially. Surgical interventions may be considered if there is a failure of medical management or in complicated cases.
Answer 3:
C) Chronic pelvic pain
Explanation 3:
Chronic pelvic pain can persist as a long-term complication in patients with a history of tuboovarian abscess, and it may necessitate ongoing management and follow-up care.
Incorrect Answer A) Ovarian cyst formation:
Ovarian cyst formation is not a typical long-term complication of tuboovarian abscess. While ovarian cysts can occur, they are not directly associated with the abscess itself, and the focus is primarily on managing the inflammatory process during treatment.
Incorrect Answer B) Recurrent pelvic inflammatory disease (PID):
Recurrence of PID is a concern, but it is not the most common long-term complication after successful treatment of a tuboovarian abscess. Appropriate management and follow-up can help prevent recurrent episodes.
Incorrect Answer D) Ectopic pregnancy:
Ectopic pregnancy is a potential concern, but it is not a direct long-term complication of a resolved tuboovarian abscess. The emphasis is on fertility preservation and monitoring for chronic symptoms rather than an increased risk of ectopic pregnancy.
Answer 4:
C) Percutaneous drainage
Explanation 4:
Percutaneous drainage may be considered in cases of large, complex tuboovarian abscesses where there is a need to drain accumulated fluid or pus. This approach can be used in conjunction with antibiotic therapy.
Incorrect Answer A) Hysterectomy:
Hysterectomy, the removal of the uterus, is not typically the primary therapeutic approach for managing a tuboovarian abscess. The focus is usually on preserving fertility and addressing the infection rather than removing the uterus.
Incorrect Answer B) Oophorectomy:
Oophorectomy, the removal of one or both ovaries, is generally reserved for severe cases or when there is a specific indication. It is not the primary therapeutic approach for managing a tuboovarian abscess, especially if fertility preservation is a priority.
Incorrect Answer D) Uterine artery embolization:
Uterine artery embolization is a procedure used to treat certain conditions such as fibroids or abnormal bleeding. It is not a standard therapeutic approach for managing tuboovarian abscess. The focus in this context is on drainage and antibiotic therapy.
