Concomittant occurence of well-differentiated thyroid carcinoma metastasis and chronic lymphocytic leukemia in the same lymph node along with internal jugular vein thrombus: a case report.

Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is the most common adult leukemia. The coexistence of CLL and papillary thyroid carcinoma (PTC) is extremely rare. PTC sometimes shows microscopic vascular invasion but rarely cause a tumor thrombus in the internal jugular vein (IJV).

Diagnostic Accuracy of Ultrasound for the Evaluation of Lateral Compartment Lymph Nodes in Papillary Thyroid Carcinoma.

Aims: To evaluate the diagnostic accuracy of ultrasound (US) assessing the lateral compartment lymph node metastasis in patients with primary papillary thyroid carcinoma (PTC), and to demonstrate the incidence and patterns of the lateral lymph node metastasis.

Methods: We retrospectively reviewed 198 patients with primary PTC who underwent thyroidectomy in addition to modified lateral neck dissections (MLND) involving level II to level V due to clinically positive lateral neck disease. A skilled and experienced single operator performed all US examinations.

Effect of prophylactic central neck dissection on the surgical outcomes in papillary thyroid cancer: experience in a single center.

Purpose: Morbidity due to papillary thyroid carcinoma (PTC) is increased mostly due to lymph node (LN) metastases, which lead to reoperations and complications associated with these operations. The aim is to compare the outcomes of PTC having total thyroidectomy and prophylactic central lymph node dissection (TT + PCND) with patients having total thyroidectomy (TT) alone.

Methods: This study is a retrospective cohort analysis of 358 PTC patients that were operated by a single surgeon in a single center.

Evaluation of lumbar multifidus muscle in patients with lumbar disc herniation: are complex quantitative MRI measurements needed?

Objective: To assess the composition of lumbar multifidus muscle, in patients with unilateral lumbar disc herniation causing nerve compression, using quantitative and qualitative magnetic resonance imaging (MRI) measurement methods.

Methods: Two radiologists retrospectively measured MRI signal intensity of the multifidus muscle, as high intensity represents more fat, and visually graded the fat content using a 5-point grading system in patients with unilateral subarticular lumbar disc herniation. Findings from the herniated and contralateral sides were compared.

The prevalence and characteristics of the subclavius posticus muscle in the adult population on MRI.

Purpose: The subclavius posticus muscle (SPM) is an aberrant muscle, and the presence of the SPM has a clinical significance, since the SPM might lead to thoracic outlet syndrome (TOS). To date, no radiological study has been evaluated the prevalence of the SPM in the adult population. In this study, we aimed to assess the prevalence of the SPM using magnetic resonance imaging (MRI).

The preliminary results of a new CT-guided periradicular cervical steroid injection technique: safety and feasibility of the lateral peri-isthmic approach in 28 patients.

Background: Computed tomography (CT)-guided cervical nerve injections are broadly being used in the treatment of cervical radiculopathy; however, catastrophic complications have been reported. Herein, we aimed to evaluate the efficacy, feasibility, and safety of a novel CT-guided cervical injection technique.

Materials And Methods: We prospectively performed cervical injections in 28 patients with cervical radiculopathies using a novel CT-guided cervical transforaminal injection technique; lateral peri-isthmic approach in which the tip of the needle advanced to the lateral cortex of the isthmus instead of the foraminal area.

Methods: At the first stage, 3D color Doppler ultrasound (3D-CDUS) scans were made to detect baseline perfusion of each testicle in 12 male albino Wistar rats. Then, the left testicles of all rats were twisted 180° clockwise, and 3D-CDUS recordings were repeated.

The value of ultrasound elastography-guided fine-needle aspiration biopsy of thyroid nodules in reducing nondiagnostic results.

Fine-needle aspiration biopsy (FNAB) is an important tool for diagnosing thyroid nodules; however, nondiagnostic results are a problem with FNAB. We evaluated the optimal targeting area of thyroid nodules for FNAB by using ultrasound elastography (USE) to reduce nondiagnostic results. Between December 2008 and November 2010, 96 consecutive prospective subjects scheduled to undergo FNAB were included in the study.

Diagnosis of acute appendicitis with unenhanced helical CT: a study of 130 patients.

The aim of this study was to determine the sensitivity, specificity, and diagnostic accuracy of helical computed tomography (CT) without oral, intravenous, or rectal administration of contrast material in confirming the diagnosis of acute appendicitis in patients with suggestive clinical and laboratory findings. One hundred and thirty patients with suspected acute appendicitis underwent an unenhanced helical CT scan. Scans were obtained in a single breath-hold from the level of umbilicus to the pubic symphysis using a 5-mm collimation.
