Percutaneous cryoablation of follicular thyroid carcinoma metastasis to the pancreas.

The following is a technical report of the successful cryoablation of pancreatic metastasis originating from follicular thyroid carcinoma. The patient was a 72-year-old female who underwent total thyroidectomy and radioiodine ablation for follicular carcinoma. One year after surgery, a positron emission tomography-computed tomography (PET-CT) examination, performed to demonstrate the source of the increased thyroglobulin, showed a fluorodeoxyglucose (FDG) avid mass located in the body of the pancreas.

Shear wave elastography of temporomandibular joint disc and masseter muscle stiffness in healthy children and adolescents: a preliminary study.

Objectives: Shear wave elastography (SWE) are promising techniques in diagnosing temporomandibular joint (TMJ) disc and masseter muscle disorders. To investigate normative stiffness values of the TMJ disc and masseter muscle by SWE in children and adolescents.

Methods: This prospective study evaluated 123 TMJ discs and masseter muscles in 123 subjects.

Diagnostic utility of arterial spin labeling in identifying changes in brain perfusion in patients with carbon monoxide poisoning.

Objective: Carbon monoxide (CO) poisoning is one of the most common poisonings worldwide. The affinity of hemoglobin for CO is significantly higher than that for oxygen, and the formation of carboxy-hemoglobin leads to a decrease in the capacity of blood to transport oxygen to tissues, tissue hypoxia, and early perfusion changes in the affected tissue. This study aimed to investigate the utility of arterial spin labeling perfusion imaging (ASL-PI) in revealing cerebral vascular hemodynamic changes in patients presenting to the emergency room with CO poisoning and to compare findings with those from diffusion-weighted imaging (DWI).

Shear Wave Elastography in the Evaluation of the Kidneys in Pediatric Patients with Unilateral Vesicoureteral Reflux.

Objectives: To evaluate the ability of shear wave elastography (SWE) to detect renal parenchymal scar formation in patients with vesicoureteral reflux.

Methods: We prospectively evaluated 49 patients with unilateral grade 2 or higher-degree VUR. All patients underwent dimercaptosuccinic acid (DMSA) scintigraphy for evaluation of the renal parenchymal scar.

A Rare Cause of Inguinal Mass: Round Ligament Cyst.

Round ligament mesothelial cyst is a rare cause of inguinal mass. Round ligament cysts are generally diagnosed during operation in cases who are operated with a pre-diagnosis of inguinal hernia. In this study, we aim to present two cases, who have applied to our clinic with the complaint of a mass in inguinal region and who are diagnosed as round ligament cyst, together with their ultrasound, magnetic resonance images and operation images.

Quantitative Assessment of Thyroid, Submandibular, and Parotid Glands Elasticity With Shear-Wave Elastography in Children.

Tissue elasticity is becoming a more commonly used parameter in evaluation of parenchyma in inflammatory diseases. Considering the changes in the thyroid and salivary glands with adolescence, determination of mean elasticity ranges with a function of age is necessary to apply ultrasound elastography more widely in the pediatric population.The thyroid, submandibular, and parotid glands of 127 healthy volunteers (66 males, 61 females; mean age = 10.

Utility of lung radiodensity ratios in diagnosis of radiolucent foreign body aspiration in children: a practical approach.

Objective: To evaluate the utility of radiodensity ratio between lungs on chest X-ray for the diagnosis of radiolucent foreign body aspiration (FBA) in children.

Methods: X-rays of 33 patients with confirmed diagnosis of FBA by bronchoscopy were compared to 66 control patients. We divided the study group into three subgroups: symmetric (13-patients), right-oblique (RO;12-patients) and left-oblique (LO;8-patients).

A rare cause of vomiting: annular pancreas.

Annular pancreas is a rare congenital anomaly that consists of a ring of pancreatic tissue partially or completely encircling the second part of the duodenum. It can affect anyone from neonates to adults, and is difficult to diagnose because it can present in a wide range of clinical conditions. Although cases have also been reported in adults, symptomatic cases are often referred in infancy or early childhood.

In vivo assessment of placental elasticity in intrauterine growth restriction by shear-wave elastography.

Purpose: In this study, we evaluated the placental elasticity in vivo by shear-wave elastography in pregnant women under follow-up for intrauterine growth restriction (IUGR) and compared the elasticity values to normal pregnancies.

Material And Methods: This prospective study included 42 pregnant women with a possible diagnosis of intrauterine growth restriction based on obstetrical grayscale and Doppler ultrasonography and 42 women with a normal pregnancy during the 2nd and 3rd trimester. During follow-up examinations, seven fetuses showed an increased growth and were delivered with a birth-weight above the 10 percentile.

Breast diseases in children: the spectrum of radiologic findings in a cohort study.

Purpose: We aimed to investigate the spectrum of radiologic findings and referral reasons for breast diseases in children considering age-appropriate presentation.

Methods: Our retrospective cohort study included 348 consecutive pediatric patients aged <19 years (median, 13 years) referred to radiology with a clinical presentation between 2005 and 2016. Radiologic findings were reviewed in four age ranges (0-2 years, 2-8 years, 8-15 years, >15 years).

Diffusion-weighted MRI for differentiating Wilms tumor from neuroblastoma.

Purpose: Wilms tumor (WT) and neuroblastoma (NB) are the most common pediatric abdominal malignant neoplasms of the kidney and adrenal gland. Differentiating them from each other is essential since their treatments are different. Here, we aimed to show the diffusion characteristics of WT and NB for differentiation.

The role of shear wave elastography in the assessment of placenta previa-accreta.

Objective: To evaluate the value of shear wave elastography (SWE) in the prediction of morbidly adherent placenta.

Methods: Forty-three women with normal placental location and 26 women with anteriorly localized placenta previa were recruited for this case-control study. Placental elasticity values in both the groups were determined by SWE imaging.

Bilateral Cystic Adrenal Neuroblastoma with Cystic Liver metastasis.

Bilateral congenital cystic adrenal neuroblastoma (NB) with cystic liver metastasis is a very rare condition and only few cases have been reported in the literature. Herein we report a case of a congenital bilateral cystic adrenal NB with cystic liver metastasis and briefly discuss characteristic imaging features of cystic NB.
