OBJECTIVE: The purpose of this study is to assess the prevalence of abnormal CT findings in patients with surgically proven ruptured endometriotic cysts, as compared with those abnormal CT findings of ruptured ovarian functional cysts. MATERIALS AND METHODS: This study included 13 retrospectively identified patients with surgically confirmed ruptured ovarian endometriotic cysts and who had also undergone preoperative CT scanning during the previous seven years. As a comparative group, 25 cases of surgically confirmed ruptured ovarian functional cysts were included. We assessed the morphologic features of the cysts and the ancillary findings based on CT. RESULTS: For the endometriotic cysts, the mean maximum cyst diameter was significantly larger than that of the functional cysts (70.1 mm versus 36.4 mm, respectively, p < 0.05). The endometriotic cysts frequently had a multilocular shape and a thicker cyst wall, as compared to that of functional cysts, and these differences were statistically significant. Among the ancillary findings, endometriotic cysts showed a significantly higher prevalence of loculated ascites, ascites confined to the pelvic cavity without extension to the upper abdomen, and peritoneal strandings and infiltrations (p < 0.05). Although 11 of the 25 cases of functional cysts showed active extravasation of contrast material at the ovarian bleeding site, only one of 13 cases of endometriotic cysts showed active extravasation. CONCLUSION: The diagnosis of ruptured endometriotic cyst should be suspected for a woman in whom CT reveals the presence of multilocular or bilateral ovarian cysts with a thick wall and loculated ascites confined to the pelvic cavity with pelvic fat infiltrations.

OBJECTIVETo establish a non-invasive, repeatable and dynamic study method in endometriosis rat model using magnetic resonance imaging (MRI), in order to explore the magnetic resonance characteristics of the model.

METHODEndometrium tissues were transplanted into left abdominal walls of unmated adult female SD rats. After surgery, pathological changes were observed and MRI scanning was made for the ectopic lesions.

RESULTThe endometriosis rat model was successfully established and the ectopic lesions imaged strong hyperintense on DWI, hypointense on T1WI, hyperintense on T2WI with a clear border, without enhancement on CE-T1 WI.

CONCLUSIONThe lesions can be clearly observed in the MRI images on the endometriosis rat model established by this method, which facilitates repeat experiments and continuous observation studies.

Endometriosis is a relatively common gynecologic disease. However thoracic endometriosis syndrome is exceedingly rare among various types of external endometriosis. We experienced a case of 35-year-old woman who presented with recurrent episodes of spontaneous right-sided pneumothorax that occurred during her menstrual periods. After the localization of the disease site by means of chest radiography and computed tomography of the thorax, a chest tube was inserted after which bullectomy and pleurodesis using doxycycline were performed. A hormonal treatment with gonadotropin-releasing hormone (GnRH) agonist for 12-months was also conducted. However, right-sided pneumothorax recurred two times after these procedures. Subsequently, surgical excision of diaphragmatic lesion along with pleurodesis was underwent. To prevent recurrence, we maintained long-term GnRH agonist administration with add back therapy using low dose estrogen-progesterone. Menstruation stopped, and the chest pain disappeared. During a 19-months follow-up period, pneumothorax did not recur. We report this case with a brief review of the concerned literatures.
