Sonoelastographic evaluation for benign neck lymph nodes and parathyroid lesions.

The aim of the study was to evaluate the performance of real-time strain sonoelastography for comparison of perithyroidal lymph nodes of Hashimoto thyroiditis patients, jugular lymph nodes of healthy individuals and parathyroid lesions. Fifty parathyroid lesions (Group 1), 52 lymph nodes in Hashimoto thyroiditis patients (Group 2) and 51 reactive jugular lymph nodes (Group 3) were examined by ultrasound, and elastography was performed for a total of 95 patients. Real-time strain sonoelastography using elasticity score (E-index) was performed.

Real-Time Sonoelastography of Parotid Gland Tumors.

Objectives: We sought to determine the performance of real-time sonoelastography in the differential diagnosis of parotid gland tumors.

Methods: Between April, 2014, and June, 2015, 54 parotid gland masses were examined by ultrasound and strain sonoelastography in 46 patients. Real-time sonoelastography using the elasticity score (E-index), which gives an absolute value between 0 (softest) and 6 (hardest), was performed.

Intranodal Palisaded Myofibroblastoma: Radiological and Cytological Overview.

Background: Intranodal palisaded myofibroblastoma is a benign and very rare mesenchymal neoplasm of the lymph nodes originating from differentiated smooth muscle cells and myofibroblasts.

Case Report: We report a case of intranodal palisaded myofibroblastoma in an 84-year-old woman with Parkinson's disease that presented as a left inguinal mass. The diagnosis was made using ultrasound-guided fine needle aspiration biopsy and consequent cytopathological examination that included immunohistochemical analysis.

The Role of Computerized Tomography in the Assessment of Perivesical Invasion in Bladder Cancer.

Background: The aim of the present study was to identify the contrast patterns of a tumor, and to evaluate the possibility of assessing the invasion of the perivesical fatty tissue in bladder cancer.

Material/methods: In this study, 26 patients with bladder cancer were included. Multiphasic CT examination was performed to determine the stage of the disease before radical cystectomy.

Diuretic agent and normal saline infusion technique for ultrasound-guided percutaneous nephrostomies in nondilated pelvicaliceal systems.

Purpose: Percutaneous nephrostomy (PCN) in a nondilated pelvicaliceal system is technically challenging. We describe an effective method to achieve transient dilatation of the pelvicaliceal system via induction of diuresis using infusion of a diuretic agent in normal saline, therefore allowing easier access to the pelvicaliceal system.

Methods: Under real-time ultrasound guidance, the technique had been tested in 22 nephrostomies with nondilated system (a total of 20 patients with 2 patients having bilateral nephrostomies) during a 5-year period.

US and MDCT findings in a caudal blind ending bifid ureter with calculi.

Herein we present a rare ureteric duplication anomaly; blind ending bifid ureter with calculi which is asymptomatic unless complicated by infection, reflux, calculi or malignancy. The diagnosis is often missed at intravenous urography (IVU) and US because the ipsilateral ureter and kidney are grossly normal. In this case the diagnosis was established with ultrasound (US) and mainly with multidetector computerized tomography (MDCT) imaging using multiplanar reformats and 3-D reconstructions which were unique to this case.

A computational study on the characteristics of airflow in bilateral abductor vocal fold immobility.

Objectives/hypothesis: To evaluate airway sufficiency and airflow dynamics in a group of patients who underwent a posterior transverse laser cordotomy (PTLC) procedure.

Study Design: Mixed methods research, university hospital setting.

Methods: Sixteen patients who underwent a PTLC procedure volunteered to be involved in this study.

Computerized tomography for detecting perivesical infiltration and lymph node metastasis in invasive bladder carcinoma.

Objectives: Computerized tomography (CT) is used in the preoperative staging of invasive bladder carcinoma. We evaluated the role of CT for detecting perivesical invasion and lymph node metastases in patients who had undergone radical cystectomy and pelvic lymphadenectomy for invasive bladder carcinoma.

Patients And Methods: We retrospectively analyzed the clinical and pathological data of 100 patients with invasive bladder carcinoma who had undergone radical cystectomy.

Ruptured iliac aneurysm presenting as lumbosacral plexopathy.

Isolated internal iliac aneurysms are rare. Unless rupture occurs, they usually remain asymptomatic. In this paper, a patient with a ruptured internal iliac aneurysm that resulted in chronic stage hematoma causing lumbosacral plexopathy and erosion of the pelvic bony structures is presented, along with magnetic resonance imaging (MRI) and computed tomography (CT) findings.

3-Dimensional computerized tomography in follow-up of patients with urinary diversion.

Introduction: The aim of our study was to evaluate the usefulness of 3-dimensional computerized tomography (3D-CT) in routine follow-up of patients who had undergone radical cystectomy and different kinds of urinary diversions and compare it with conventional CT.

Patients And Methods: Nineteen patients (18 men, 1 woman) who had undergone radical cystectomy and different kinds of urinary diversions with diagnosis of invasive bladder cancer were enrolled into the study. The mean age of the patients was 55.

Is fluid ingestion really necessary during ultrasonography for detecting ureteral stones? A prospective randomized study.

Objective: Ultrasonographic evaluation of ureteral stones is usually performed after fluid ingestion for filling the bladder to visualize the ureterovesical junction better. We hypothesized that water ingestion may decrease the imaging quality of ultrasonography for detecting ureter stones. In our prospective randomized study, the accuracy of ultrasonography for detecting ureteral stones performed with or without fluid intake were evaluated.

Clitoral metastasis from transitional cell carcinoma of the renal pelvis: CT and MRI findings.

Metastatic tumors of the clitoris are extremely rare. We report a case of clitoral metastasis in a 75-year-old woman who was treated for transitional cell carcinoma of renal pelvis 2 years ago. The computed tomography and magnetic resonance imaging findings are presented with a short review of the literature.

[Late presentation of an extrarenal pseudoaneurysm in a renal transplant patient: CT and color Doppler US findings (case report)].

Vascular complications associated with renal transplants are a significant cause of graft dysfunction or failure. The most common complications are arterial and venous stenoses/thromboses, intrarenal and extrarenal arteriovenous fistulas, and pseudoaneurysms. In this case report, an extremely rare complication following renal transplantation, an extrarenal pseudoaneurysm, is presented with CT, gray scale, and color Doppler US findings.

The value of transrectal ultrasound guided needle aspiration in treatment of prostatic abscess.

Introduction: Prostatic abscess (PA) is a very uncommon disorder. The value of transrectal ultrasound (TRUS) guided aspiration in the treatment of PA has not been clearly defined. We present our experience with six such patients.

Efficacy of transrectal ultrasonography in the evaluation of hematospermia.

Objective: To assess the efficacy of transrectal ultrasonography (TRUS) in the evaluation of hematospermia.

Material And Methods: This study included 54 patients with hematospermia. Patients age range was between 25 and 75 years (mean=49.

[Omental infarction: CT findings (case report)].

Omental infarction, the end result of impaired perfusion of the greater omentum, is an uncommon cause of acute abdominal pain. Because its clinical symptoms are nonspecific, it is usually confused with more common conditions such as appendicitis or cholecystitis. Consequently, the diagnosis is generally made intraoperatively.

Virtual cystoscopy in the evaluation of bladder tumors.

Objective: The objective of this study was to investigate the value of contrast material-filled virtual cystoscopy in the detection of bladder tumors.

Materials And Methods: Thirty-nine patients who had recent diagnosis or were followed up due to priory history of bladder tumor underwent virtual cystoscopy. After the intravenous injection of contrast medium, the bladder was examined with helical computed tomography (CT) scan.

[Cross-sectional imaging findings in intradiverticular bladder tumors: Case report].

Neoplasms originating in bladder diverticula are characterized by early transmural invasion and a tendency for higher histopathological grades, which make prompt diagnosis and treatment crucial in these tumors. Filling defects caused by intradiverticular tumors cannot always be visualized in intravenous urography and/or cystography. Cross-sectional imaging methods including ultrasonography, computed tomography and magnetic resonance imaging have been used singly or in combination in neoplasms of the lower urinary tract.
