    Evaluation of the optic nerve using strain and shear-wave elastography in pre-eclampsia
    (W B Saunders Co Ltd, 2019) Asal, N.; Sayan, C. D.; Gokcinar, N. B.; Sahan, M. H.; Dogan, A.; Inal, M.
    AIM: To investigate the utility of strain elastography and shear-wave elastography for assessing optic nerve involvement in pre-eclampsia. MATERIAL AND METHODS: A total of 120 eyes were evaluated in 60 cases consisting of 30 participants in the pre-eclamptic and 30 participants in the non-pre-eclamptic pregnant patient group. The findings of strain and shear-wave elastography, grey-scale sonography, and optical coherence tomography were compared between the groups. RESULTS: There was a statistically significant difference for the average shear-wave elastography values between groups (17.6 +/- 4.1 and 9.4 +/- 2 kPa, p<0.01). The analysis of the strain elastography types also revealed a statistically significant difference between the groups (p<0.01). A statistically significant difference was found for the average values of the optic nerve sheath diameter between the two groups (p<0.05). A statistically significant difference was found in the average value of the superior quadrant of the retina nerve fibre layer between the groups in optical coherence tomography analysis (p=0.04). The peripapillary choroidal thickness values of pre-eclamptic pregnant women were higher than that of non-preeclamptic pregnant women, but the difference was not significant (p>0.05). CONCLUSION: Stiffness of the optic nerve was greater in patients with pre-eclampsia in the study. Elasticity changes in the optic nerve may be generally attributed to microvascular and biomechanical changes secondary to increased hypertension in pre-eclamptic patients. Elastography could be used as assistive diagnostic techniques to evaluate the optic nerve structure changes in pre-eclampsia. (C) 2019 The Royal College of Radiologists. Published by Elsevier Ltd.

    Ruptured cystic teratoma associated with mucinous cystadenoma in a pregnant woman
    (Wolters Kluwer Medknow Publications, 2019) Aydin, O.; Pehlivanli, F.; Karaca, G.; Aydin, G.; Sayan, C. D.; Atasoy, P.; Daphan, C. E.
    Mature cystic teratoma is the most common ovarian neoplasm. However, mucinous cystadenoma with teratoma has been very rarely reported in literature. This case report, which is very rare, describes a clinical entity not previously reported in literature. A 34-year-old pregnant woman presented in the 23rd gestational week with severe right lower quadrant pain. She was diagnosed with acute abdomen and was then treated surgically. During the surgical intervention, a spontaneously ruptured mass was detected in the right ovary. This was reported histopathologically as a mature cystic teratoma in collision with mucinous cystadenoma. To the best of our knowledge, this case report is the first to have identified a ruptured mature cystic teratoma in collision with mucinous cystadenoma in a pregnant woman.
