Objective To summarize the findings of ultrasonography and CT in hemorrhage corpus luteum cyst (HCLC) and their clinical value in the diagnosis of the disease. Methods The medical records of 53 patients with HCLC treated in our hospital from August 2013 to April 2016 were analyzed retrospectively. The ultrasonography and CT findings were summarized. The diagnostic accordance rates were compared between the two methods. Results A total of 15 cases were diagnosed by ultrasonography in 41 cases, and the diagnostic accuracy was 36.6%, a total of 43 cases were diagnosed by CT, and the diagnostic accuracy was 81.1% (P＜0.05). Patients with HCLC were divided into ruptured type and unruptured type. The ultrasonography findings of patients with ruptured HCLC complicated with hemorrhage were pelvic cystic and solid tumors, ultrasonogram showing solid moderate to strong echo with irregular shape and with large amount of pelvic and peritoneal effusions. The findings of patients with unruptured HCLC were multilocular separated cystic masses in the pelvic cavity, separation distributing from the center to the periphery radial distribution, namely, octopus-like distribution, or with stratified sign. CT showed cystic masses, inhomogeneous density, incomplete cyst wall, with break, blood or blood clots surrounding cyst, low density shadow in abdominal cavity and pelvic cavity and high density shadow in cysts. Conclusion Compared with abdominal ultrasonography, the accordance rate of CT in the diagnosis of HCLC is higher and application value is higher. Besides, CT is more conducive to differential diagnosis of menopause, appendicitis, ectopic pregnancy rupture, ovarian cyst torsion and other diseases and can reduce misdiagnosis. Combined with ultrasonography signs, patients can be typed and it ultimately provide references for clinical treatment.
