2. Peritoneal lymphomatosis. A case report
ABSTRACT Introduction: Involvement of the peritoneum occurs very rarely and is exceptional as an exclusive extranodal presentation of lymphomas. In most cases lymphomas associated with this rare entity are high-grade ones. PL secondary to high-grade nodal lymphoma is more frequent than primary peritoneal lymphoma, and there are only a few cases of the latte

4. Robotic excision of vaginal pouch in ovotesticular disorder of sexual development
ABSTRACT Purpose: Ovotesticular disorder of sexual development (DSD) is the rarest of DSDs with an incidence of 1:20000 (1). Management of vaginal pouches in such cases is warranted for symptomatic presentations and laparoscopy is considered the gold standard treatment (2). We report a rare case of robotic excision of a large symptomatic vaginal pouch in a

5. Comparison of Clinical Examination and Various Imaging Modalities in the Diagnosis of Head and Neck Cancer
Abstract Introduction Squamous cell Carcinoma of the Head and Neck (HNSCC) is the most common tumor entity of malignant processes in the head and neck area. Due to the metastasizing behavior of these tumors, the staging is indispensable for the treatment planning and requires imaging techniques, which are sensitive, specific, and as far as possible cost-eff

6. Staghorn renal stones: what the urologist needs to know
ABSTRACT Patients with staghorn renal stones are challenging cases, requiring careful preoperative evaluation and close follow-up to avoid stone recurrence. In this article we aim to discuss the main topics related to staghorn renal stones with focus on surgical approach. Most of staghorn renal stones are composed of struvite (magnesium ammonium phosphate) a

7. Role of elastography strain ratio and TIRADS score in predicting malignant thyroid nodule
ABSTRACT Objective: Ultrasonography (US) is the most accurate and cost-effective imaging method in diagnosis of thyroid nodules. A practical thyroid imaging reporting and data system (TIRADS) for thyroid nodules has been proposed to classify nodules of the thyroid gland to solve the problem of nodule selection for fine needle aspiration cytology (FNAC).

8. Aspiration with or without lavage in the treatment of acute suppurative thyroiditis secondary to pyriform sinus fistula
ABSTRACT Objective There is currently no consensus regarding the optimal management of acute suppurative thyroiditis (AST) secondary to pyriform sinus fistula (PSF). To investigate the benefits and adverse events of aspiration with or without lavage for the treatment of AST secondary to PSF. Subjects and methods This was a retrospective analysis of consecu

9. Diagnostic accuracy of contrast-enhanced ultrasound for detecting bland thrombus from inferior vena cava tumor thrombus in patients with renal cell carcinoma
ABSTRACT Purpose: To evaluate the role of contrast-enhanced ultrasound (CEUS) in differentiating bland thrombus from tumor thrombus of the inferior vena cava (IVC) in patients with renal cell carcinoma (RCC). Materials and Methods: We retrospectively investigated 30 consecutive patients who underwent robot-assisted radical nephrectomy with IVC thrombectomy

10. Ultrasound Versus Contrast-Enhanced Magnetic Resonance Imaging for Subclinical Synovitis and Tenosynovitis: A Diagnostic Performance Study
OBJECTIVES: Radiographic manifestations of synovitis (e.g., erosions) can be observed only in the late stage of rheumatoid arthritis. Ultrasound is a noninvasive, cheap, and widely available technique that enables the evaluation of inflammatory changes in the peripheral joint. In the same way, dynamic contrast-enhanced magnetic resonance imaging (MRI) enabl
