卵巢癌特殊部位转移复发合并肠梗阻误诊临床分析OA

Objective To investigate the causes of misdiagnosis in ovarian cancer with rib metastasis as a recurrence site,in order to improve the diagnostic ability of clinicians.Methods A retrospective analysis was conducted on the clinical characteristics and imaging data of a patient with ovarian cancer who had metastasis and recurrence in the ribs and was misdiagnosed as having metastasis in the liver,spleen,and intestines at the 980th Hospital of Joint Logistics Support Force of the PLA in September 2025.Results This patient had a history of ovarian cancer and presented mainly with progressive intestinal obstruction(difficulty in defecation,abdominal distension,and abdominal pain).Abdominal CT showed a patchy enhancing lesion at the left anterior margin of the liver,suggestive of metastasis,which was closely related to the intestinal tract.The walls of the transverse colon and descending colon were slightly thickened.Initially,it was misdiagnosed as metastasis in the liver and spleen area and the intestinal tract.After conservative treatments such as gastrointestinal decompression and enema,the symptoms did not show significant improvement.Therefore,an abdominal exploration and intestinal adhesion release surgery were performed to relieve the intestinal obstruction.Further,a puncture biopsy of the chest mass was conducted under ultrasound guidance,and it was confirmed as bone metastasis of ovarian cancer.The misdiagnosis period was 20 d.Subsequently,local radiotherapy and chemotherapy were performed,and the metastatic lesions significantly shrank.The carbohydrate antigen 125 level returned to normal.Conclusion Rib metastasis in ovarian cancer is rare,and its imaging manifestations may mimic lesions in the hepatosplenic region or digestive tract.By improving imaging interpretation skills and conducting multidisciplinary team consultations,the rate of misdiagnosis can be reduced in clinical practice.
