The utility of diffusion-weighted magnetic resonance imaging in differentiation of endometriomas from hemorrhagic ovarian cysts

The aim was to determine the utility of diffusion-weighted magnetic resonance imaging (DW MRI) and apparent diffusion coefficient (ADC) measurements in differentiation of endometrioma and hemorrhagic ovarian cyst. A total of 24 female patients who underwent pelvic MRI with an initial diagnosis of ovarian cyst were included in the study. The final diagnosis was endometrioma in 12 patients and hemorrhagic ovarian cyst in 12 patients. We observed significantly lower ADC values in endometriomas compared with hemorrhagic ovarian cysts in all b values. DW MRI with quantitative ADC measurements can be used for differentiation of endometrioma from hemorrhagic ovarian cysts.

Sonographic and sonoelastographic findings of a rarely seen soft tissue tumor: eccrine spiradenoma

Eccrine spiradenoma is a rare benign tumor originating from sweat glands. Its sonographic characteristics have been described in only a few reports, and there is no such report available that describes sonoelastographic findings of this tumor. In this case report, we aimed to define the sonographic and sonoelastographic findings of a benign eccrine spiradenoma.

Elastographic Findings of Achilles Tendons in Asymptomatic Professional Male Volleyball Players

Elastography is a new sonographic technique that evaluates the elasticity of different tissues such as the Achilles tendon. In this study, we aimed to investigate the elastographic findings of Achilles tendons in professional athletes in comparison with healthy volunteers.

Idiopathic postpartum intussusception: a rare cause of acute abdominal pain.

Objectives: To present a case with acute abdominal pain due to idiopathic intestinal intussusception diagnosed by ultrasound and computed tomography (CT) during the early postpartum period. Clinical Presentation and Intervention: A 21-year-old female patient was admitted to our hospital with abdominal pain, nausea and emesis after a normal vaginal delivery. Laboratory tests done at admission were within normal limits except for leukocytosis. Physical examination revealed abdominal distention, guarding and rebound tenderness. Abdominal ultrasound and oral contrast-enhanced CT showed a complex mass in the hypogastrium, with a typical configuration of intussusception. Emergent laparotomy revealed ileoileal invagination approximately 70 cm to the ileocecal valve but no lead point. A partial ileal resection was performed. Conclusion: This case shows that when intussusception is suspected, an abdominal ultrasound should be performed even in patients with atypical symptoms. CT may be used to confirm the diagnosis.

Renal Cell Carcinoma Metastasis to Ipsilateral Parotid and Submandibular Glands: Report of a Case with Sonoelastographic Findings

Summary Background Renal cell carcinoma (RCC) – also known as hypernephroma or grawitz tumor – accounts for 3% of the adulthood malignancies. Approximately 30–40% of the patients have metastasis at the time of the diagnosis and most common sites for metastasis are lung, regional lymph nodes, bone and liver. A total of 8–14% of the patients with RCC has head and neck metastasis. However, metastasis to major salivary glands is rarely seen. In this paper, we aimed to report a RCC case with metastasis to parotid and submandibular glands that has the same sonographic and sonoelastographic findings with the primary tumor. Case Report 66-year old woman with RCC history was referred to our radiology department for neck ultrasound (US) with painful swelling in the right parotid gland region. A well-defined, 37×21 mm sized hypoechoic heterogeneous solid mass was detected in the superficial-deep lobe of the right parotid gland. The mass was prominently hypervascular in color Doppler ultrasonography scan. Coincidentally, a 13×13 mm hypoechoic lobulated solid mass was detected in the right submandibular gland with similar sonographic findings. Real-time sonoelastography (SEL) was performed to the masses and both of them were blue-green colored that indicates hard tissue. An US and SEL evaluation was also performed to the renal mass (RCC) of the patient. The primary mass was also similar in sonographic and SEL appearance as salivary gland masses. In the patient history, she revealed chemotherapy-radiotherapy treatment 1.5 years ago due to inoperable mass in the mid-lower pole of the left kidney diagnosed as clear cell RCC with vascular invasion, liver, lung and brain metastasis. Because of known primary tumor, the masses in the salivary glands were suspected to be metastatic and a tru-cut biopsy was performed. Pathological result was reported as clear cell RCC metastasis. Conclusions The etiology of RCC is still unknown and metastatic involvement can be seen at unexpected tissue and organs. Metastatic disease should be considered when a salivary gland mass detected in patients with RCC history. SEL examination would be helpful in differentiation of the origin of the metastatic lesion with known SEL features.

Transabdominal Sonographic Study of the Cavum Vergae Detection Rate in Healthy Third-Trimester Fetuses

We aimed to measure the thickness and volume of the cavum vergae by sonography in fetuses at gestational ages of 25 to 41 weeks to determine the relationship of cavum vergae thickness and volume with gestational age and biparietal diameter and to estimate the rate of cavum vergae closure in relation to gestational age.

Fetal aorta larger than the main pulmonary artery on the three-vessel view: Correlation with postnatal echocardiographic findings.

This study investigated postnatal cardiac anomalies determined by postnatal echocardiography in fetuses with the ascending aorta (AA) diameter larger than that of the main pulmonary artery (MPA) on the three‐vessel view (3VV).
