Sclerochoroidal calcification (SCC) is a frequent masquerader of choroidal melanoma with important systemic associations such as hyperparathyroidism and parathyroid adenoma. Herein, we describe a case of a 67-year-old male who presented with an amelanotic choroidal lesion in the right eye (OD) and a history of kidney stones. Ultrasonography showed the lesion to be flat and calcified OD. Incidentally, a subclinical calcified plaque was also found in the fellow eye. Optical coherence tomography showed an elevated suprachoroidal mass in a table mountain configuration OD and flat configuration left eye, consistent with type 4 and type 1 SCC...

REVIEW
Matthew J Kaptein, Elaine M Kaptein
We propose that renal consults are enhanced by incorporating a nephrology-focused ultrasound protocol including ultrasound evaluation of cardiac contractility, the presence or absence of pericardial effusion, inferior vena cava size and collapsibility to guide volume management, bladder volume to assess for obstruction or retention, and kidney size and structure to potentially gauge chronicity of renal disease or identify other structural abnormalities. The benefits of immediate and ongoing assessment of cardiac function and intravascular volume status (prerenal), possible urinary obstruction or retention (postrenal), and potential etiologies of acute kidney injury or chronic kidney disease far outweigh the limitations of bedside ultrasonography performed by nephrologists...

Urinary tract infection is the most common complication after kidney transplant that can cause graft loss. An early diagnosis of urinary infections decreases morbidity and mortality. Besides clinical and laboratory examinations, ultrasonography is considered as the primary imaging modality for the diagnosis of urinary tract infections. Here, we report a 53-year-old woman who presented with fever and pain at surgical site. Ultrasonography examination showed multiple, ill-defined or irregularly margined hypoechoic areas within the cortex...

A 47-year-old male patient underwent living-related renal transplant. On day 3 posttransplant, without evidence of associated clinical symptoms, the patient's serum creatinine levels had increased. The patient was given immunosuppressive medication, and a followup Doppler ultrasonography revealed hypoechoic areas in the inferior pole of the renal parenchyma. Eventually, on day 25, there was no perfusion in the superior and inferior poles of the transplanted kidney. No venous flow was shown in the middle segment, and only arterial vascularization with a high resistive index and negative diastolic phase was observed...

BACKGROUND: Vascular calcification (VC) is common in type 2 diabetes, and is associated with cardiovascular complications. Recent preclinical data suggest that metformin inhibits VC both in vitro and in animal models. However, metformin's effects in patients with diabetic VC have not previously been characterized. The present study investigated the association between metformin use and lower-limb arterial calcification in patients with type 2 diabetes and high cardiovascular risk. METHODS: The DIACART cross-sectional cohort study included 198 patients with type 2 diabetes but without severe chronic kidney disease...
