However, spontaneous intraperitoneal bladder rupture as a result of radiation cystitis following radiotherapy for cervical cancer is extremely rare. Case presentation: We report a 52-year-old patient who received radiation therapy for cervical cancer 15 years prior to presentation. Eight years prior to presentation, she developed recurrent abdominal distension, oliguria, and ascites. Following ascites drainage and supportive treatment, all symptoms were relieved. However, all symptoms subsequently recurred every few months. The patient underwent exploratory laparotomy twice. The first exploratory laparotomy in July 2015 found no specific abnormalities. The second exploratory laparotomy in November 2016 found an intraperitoneal bladder rupture, and the patient underwent surgical repair. The ascites subsequently resolved. Conclusion: The occurrence of spontaneous intraperitoneal bladder rupture after radiation therapy for cervical cancer is rare. The prognosis is good when diagnosis and treatment are prompt.展开更多

Resection of isolated extrahepatic metastasis of HCC has been advocated to obtain a possibility of long-term survival. However, it is a challenge for clinicians to detect implantation metastasis of spontaneously ruptured HCC. Accurate re-staging plays the most important role in making a decision on isolated metastasis resection. 18F-fluorodeoxyglucose(18F-FDG) positron emission tomography/computed tomography(PET/CT) is useful in detecting intraabdominal implantation metastasis from a variety of malignancies and shows superior accuracy to conventional imaging modalities in determining the location of metastasis. We present one patient with a new isolated pelvic implantation metastasis detected by 18F-FDG PET/CT and pathologically confirmed by PET/CT-guided percutaneous biopsy, who had a history of resection of spontaneously ruptured HCC two years ago. The patient's condition was stable at the 6-mo follow-up after resection of the isolated pelvic metastasis.展开更多

We present a rare case of bilateral unstable pelvic fractures associated with bilateral segmental femoral shaft fractures. We have proposed a mechanism of such complex injury pattern and discussed the plan of management. We believe that a timely and aggressive surgical inter- vention to fix all the major fractures soon after medically stabilizing the patient helped our patient tc overcome these serious and lethal injuries. It is necessary to establish an optimal protocol for man- agement of such complex fractures by conducting prospective and multicentric studies in the future.展开更多
