CT Diagnosis of Gynecological Acute Abdomen

Objective To investigate the CT features of gynecological acute abdomen,and to improve the diagnosis of gynecological acute abdomen.Methods The clinical and imaging data of 35 patients with gynecological acute abdomen were analyzed retrospectively.Results CT scans showed adnexal thickening and pelvic effusion in 12 patients with acute pelvic inflammation,cystic low density area in uterus rectum lacuna,pericardial effusion,fuzzy boundaries,annular edge enhancement and no enhancement in intracapsular low density area in 4 patients with pelvic abscess,round mixed density mass in uterus rectum lacuna and attachment area(42-65 HU),fuzzy boundaries,envelope enhancement,pelvic effusion and no intracapsular density enhancement in 6 patients with ectopic gestation and corpus luteum rupture,unevenly mixed density cystic lesion with thin-walled and multi-room structures,fuzzy boundaries and irregular multi-ring enhancement in 4 patients with endometriosis,and single or multiple room cystic mass with uniform thin-walled structures,high-density hematocele(40-75 HU),cyst wall enhancement and no intracapsular density enhancement in 3 patients with hemorrhagic ovarian cystadenoma torsion.Conclusion CT scan plays a supporting role in the clinical diagnosis of gynecological acute abdomen.It can comprehensively display the anatomical structures and pathological changes of pelvic tissues and organs and quickly diagnose the cause of gynecological acute abdomen.Therefore,CT scan can be used as the preferred method for clinical diagnosis of gynecological acute abdomen in most patients except childbearing age women and children.
