Assessing the diagnostic and therapeutic value of submandibular gland elastography in patients with immunoglobulin G4-related sialadenitis.

Objectives: : To investigate the utility of shear wave elastography values (SWE) in differentiating IgG4-related submandibular sialadenitis (IgG4-RSS) from healthy individuals and in monitoring the response to glucocorticoid treatment.

Methods: : Patients with IgG4-RSS who underwent ultrasound between 2017 and 2023 were included. Gland size, border, internal echo pattern, vascularity, and SWE were measured.

Survey of Dietary Habits and Physical Activity in Japanese Patients with Non-Obese Non-Alcoholic Fatty Liver Disease.

The incidence of non-obese non-alcoholic fatty liver disease (NAFLD), characterized by the presence of a fatty liver in individuals with a normal body mass index, is on the rise globally. Effective management strategies, including lifestyle interventions such as diet and exercise therapy, are urgently needed to address this growing public health concern. The aim of this study was to investigate the association between non-obese NAFLD, dietary habits, and physical activity levels.

A case of renal involvement in juvenile xanthogranulomatosis.

Juvenile xanthogranuloma (JXG) is a type of non-Langerhans cell histiocytosis that rarely involves other than the skin. Here, we present detailed ultrasound (US) findings, including a contrast study, of a rare JXD renal lesion. A 42-year-old woman with JXG had chronic kidney disease.

Fibrolipomatous hamartoma with macrodactyly and carpal tunnel syndrome.

A 26-year-old man presented with congenital left thumb macrodactyly. MRI showed diffuse enlargement of the left median nerve from the wrist to the digits, with particularly severe swelling of the thumb; US revealed the median nerve swelling comprised enlarged hypoechoic nerve bundles and increased hyperechoic areas around the nerve bundles. These typical cable-like and spaghetti-like appearances led to the diagnosis of fibrolipomatous hamartoma (FLH).
