Background: Epithelial tumors are the most common subgroup and are seen in 60-70% of all ovarian tumors. Serous cystadenoma and mucinous cystadenoma are the most common benign epithelial tumors. Serous cystadenomas are ovarian tumors with the highest bilateral incidence. The coexistence of tumors with different histopathology in the ovaries is extremely rare and has only been reported in a few cases in the literature. We present a case of bilateral ovarian tumor that was diagnosed as serous and mucinous cystadenoma after laparoscopic surgery. Case report: A 45-year-old female patient was admitted to our center with swelling in the pelvic region and pain in the left lumbar region. US imaging showed a cystic lesion in the right adnexal area, 4x2cm in size, well-circumscribed, containing a few thin septa, and a low echo fluid content. A cystic lesion with 6x4cm sized multilocular, well-circumscribed, slightly high echo fluid content was observed in the left adnexal area. On CT, a complex cystic lesion measuring 6x4cm was observed in the left adnexal area, pushing the left ureter laterally and causing the hydroureter. In addition, a 4x2cm cystic lesion was observed in the right adnexal area and hydroureter was observed on the right side proximal to this lesion. Both lesions were removed by surgery. On histopathologic examination, the left-sided cystic lesion was diagnosed as mucinous cystadenoma, and the right-sided cystic lesion was diagnosed as serous cystadenoma. Conclusion: The coexistence of different ovarian tumor subtypes is rare. In this article, we presented a case in which serous and mucinous cystadenoma lesions were seen together for the fourth time in the literature, according to our knowledge.

Purpose To investigate the diagnostic performance of gray‐scale ultrasound (US) and shear wave elastography (SWE) for determining salivary gland involvement primary Sjögren's syndrome (pSS). Methods In this prospective study, the salivary glands of 72 healthy volunteers and 74 participants with pSS were examined by two blinded radiologists with consensus using gray‐scale US and SWE. SWE parameters were compared between groups. The area under the curve (AUC), sensitivity, and specificity of gray‐scale US and SWE was analyzed. The correlation between SWE and clinical findings was investigated. Result The SWE parameters of the parotid and submandibular glands were significantly higher in the pSS group, but did not differ significantly based on serologic assays, Schirmer test, minor salivary gland biopsy, and comorbidities. The AUC values for gray‐scale US of the salivary glands were significantly lower than the AUC values for SWE. The elasticity modulus (kPa) of parotid gland had the highest AUC value (0.937; 95% CI, 0.901–0.973), with a sensitivity of 93.2% and a specificity of 83.3%. SWE had no correlation with age, disease duration, laboratory values, or disease activity. Conclusion SWE provides excellent diagnostic performance for submandibular and parotid gland involvement in pSS and can be used to complement gray‐scale US.

Background: Behçet's disease is a chronic inflammatory disease that can involve systemic organs and vascular structures. Arterial system involvement is rarer than the venous system, it is the major cause of death. Vertebral artery (VA) involvement is rare and there are a limited number of reported cases in the literature. In this report, we aimed to present the imaging findings of a case of Behçet's disease with a giant aneurysm originating from the right VA. Case report: A 35-year-old woman with a 10-year history of Behçet's disease applied to our center with complaints of pain on the right side of the neck. CT angiography showed a 7.5x6.5 cm sized saccular aneurysm in the superior of the right hemithorax adjacent to the mediastinum, with contrast filling the V1 segment of the VA. The VA aneurysm in our case had no relation with the subclavian artery and showed filling from the contralateral VA. The described findings were demonstrated in Doppler examination, phase-contrast MRI, conventional and CT angiography. Conclusion: Behçet's disease is a chronic inflammatory disease that can involve the arterial system. Although VA involvement has not been reported frequently, all arterial structures may be affected by this vasculitic process.

Background: Fetal ultrasonographic evaluation is a routine part of pregnancy follow-up, and examination of orbital structures is also part of the routine evaluation. Although orbital developmental anomalies are common in the neonatal period, diagnosis in the intrauterine period is not common. To our knowledge, three cases with a diagnosis of congenital orbital epidermal cysts have been reported in the literature, and two of them had fetal imaging findings. In this article, we present the pre-postnatal imaging findings of a case diagnosed with orbital cyst in the fetal period and histopathologically diagnosed as epidermal cyst in the neonatal period. Case report: A 25-year-old woman applied for ultrasonography (USG) examination at 22 weeks of gestation. A 35x45 mm cystic lesion causing proptosis, without solid component and vascularity, surrounding the optic nerve and causing its thinning was observed in the left orbit. In fetal magnetic resonance imaging (MRI), the intraorbital cystic lesion, which was hyperintense on T2W images and hypointense on T1W images, had no relationship with intracranial structures and no solid component. The lesion of the patient, followed up with a multidisciplinary approach, was shown similarly with computed tomography (CT) and magnetic resonance imaging (MRI) in the postnatal period. Subsequently, the patient underwent globe-sparing surgery, and the pathological diagnosis was made as an epidermal cyst. Conclusion: Orbital epidermal cysts are rarely seen, and detection in the fetal period is even rarer. It should be considered in the differential diagnosis of orbital cystic lesions that cause proptosis in fetal and neonatal periods.
