Evaluation of the optic nerve using strain and shear-wave elastography in pre-eclampsia.

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-pre-eclamptic 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.

Ruptured cystic teratoma associated with mucinous cystadenoma in a pregnant woman.

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.
