Multi-slice CT in differential diagnosis of female periappendiceal abscess and right salpingotubo-ovarian abscess in women / 中国介入影像与治疗学

ABSTRACT

Objective: To observe the value of multi-slice spiral CT (MSCT) in differential diagnosis of female periappendiceal abscess and right tubo-ovarian abscess in women. Methods: MSCT data of 42 female patients with peri-appendicular abscess and 35 cases of right tubo-ovarian abscess confirmed by surgical pathology were retrospectively analyzed. The differences of preoperation CT imaging features were compared between the two groups. Results: The incidence rates of free pelvic fluid, the thickness of the cecal wall, fat stranding around the appendix and/or cecum, fluid accumulation around the cecum, the thickness of the appendix wall > 3 mm, the appendix diameter > 6 mm, mass in the appendix area, anteriorly movement of the broad ligament of the uterus, extraluminal gas, appendix fecal stones, peri-ovarian fat stranding, the right ovarian mass, the thickness of the sacral uterine ligament, tube-shaped lesions and the comorbidity of left tubo-ovarian abscess were significantly different (all P 0.05). Conclusion: MSCT can display characteristic features of female peri-appendicular abscess and right tubo-ovarian abscess, and facilitate the differentiation of these two diseases.
