Diagnostic imaging of parotid gland oncocytoma: a pictorial review with emphasis on ultrasound assessment.

Parotid gland oncocytoma (PGO) is a rare benign epithelial tumor that usually occurs in the elderly population. The most common clinical presentation is a painless, slow-growing, non-tender, lobulated, and mobile mass. Histologically, it is composed of monotonous sheets of epithelial cells (oncocytes) with a central scar.

Thyroglossal duct cysts and site-specific differential diagnoses: imaging findings with emphasis on ultrasound assessment.

Thyroglossal duct cysts (TGDCs) are the most common congenital abnormality of the neck, accounting for approximately 70% of congenital neck lesions. Two-thirds of thyroglossal duct anomalies are diagnosed within the first three decades of life, with more than half being identified before 10 years of age. The age of presentation, clinical examination and imaging are essential for an accurate diagnosis.

LapBand System in super-superobese patients (>60 kg/m(2)): 4-year results.

Background: Bariatric surgery in superobese (BMI > 50 kg/m(2)) and super-superobese (BMI > 60 kg/m(2)) patients can be a formidable technical and therapeutic challenge because these patients often present multiple medical, surgical, and anesthetic risks. Only a few dedicated reports on different surgical options in this kind of patient population are available. The aim of this study is the evaluation of laparoscopic adjustable gastric banding (LAGB) results in an unselected populations of super-superobese patients operated during the last 4 years.
