ABSTRACT
Background: Uterine arterial pseudoaneurysm (UAP) is a rare cause of vaginal bleeding. Usually, UAP follows cesarean section, uterine curettage, vaginal delivery, or cervical conization and must be considered in the differential diagnosis. Here we report a very unusual case of UAP causing intra-abdominal and vaginal bleeding after cervical cerclage and its successful management through the endovascular route. Case Presentation: This 30-year-old P2L1A2 woman presented with vaginal bleeding after 7 days following hysterotomy for termination of pregnancy. At 16 weeks of her index pregnancy, she underwent cervical cerclage for cervical insufficiency, followed by an emergency hysterotomy at 20 weeks for profuse vaginal bleeding after failed medical management. On ultrasound and contrast-enhanced computed tomography (CECT), uterine dehiscence and a cervical pseudoaneurysm were detected. Dehiscence was repaired surgically, and pseudoaneurysm was successfully managed by uterine artery embolization. Conclusion: UAP is an uncommon cause of vaginal bleeding; however, it should be considered in the differential diagnosis of a woman with unusual vaginal bleeding, particularly in the postpartum or postoperative setting like cesarean section, uterine curettage, cervical conization, or cerclage. Endovascular uterine artery embolization is a minimally invasive, effective, preferred, and safe method for managing UAP.
ABSTRACT
OBJECTIVE: To assess the usefulness of post contrast Fluid attenuated inversion recovery (FLAIR), 3D T1-SPACE, and T1W magnetic resonance imaging (MRI) sequences with fat suppression in diagnosis of infectious meningitis. METHODS: 75 patients with clinical suspicion of meningitis were evaluated with post contrast FLAIR (PC-FLAIR), post contrast T1-SPACE (PC-T1-SPACE), and post contrast T1WI (PC-T1WI). Sensitivity, specificity, positive predictive value, and negative predictive value of individual sequences were assessed. RESULTS: The sensitivity of PC-FLAIR (88.4%) was greater than PC-T1-SPACE (85.5%) and PC-T1WI (82.6%), considering cerebrospinal fluid (CSF) analysis as gold standard (p < 0.05). Kappa inter-rater agreement between two radiologists was 0.921 for PC-T1-SPACE, 0.921 for PC-T1WI, and 1.0 for PC-FLAIR with a p value <0.05. Both PC-T1-SPACE and PC-FLAIR performed equally in sulcal space enhancement. PC-T1-SPACE and PC-T1WI performed better in evaluation of pachymeningeal enhancement, ependymal enhancement in cases of ventriculitis, whereas PC-FLAIR was more sensitive in assessment of basal cistern enhancement and enhancement along the cerebellar folia. CONCLUSION: Meningeal enhancement could be better appreciated in PC-FLAIR image than PC-T1WI and PC-T1-SPACE. Enhancement in PC-T1-SPACE was comparable to that of PC-T1WI. Being a T1 based spin echo sequence, PC-T1-SPACE has all the advantages of PC-T1WI in addition to its ability to differentiate meningeal enhancement from leptomeningeal vessels. Hence, PC-T1WI can be replaced by PC-T1-SPACE and PC-FLAIR can be added to routine MRI protocol in suspected case of meningitis.
