Assessment of the incidental adrenal lesion

Introduction The adrenal glands are seen on CT or MRI surrounded by fat in the peri-renal space. The right adrenal gland lies medial to the right lobe of the liver, lateral to the right crus of the diaphragm and superior...

Model to predict malignancy among Bosniak III cysts

This retrospective study over a 15-year period is to identify independent predictors of malignancy in Bosniak III (BIII) renal lesions and to build a prediction model based on identifiable clinical variables. These cysts, characterised by contrast-enhanced computed tomography (CECT), have...

The natural history of prostate cancer on MRI

Multiparametric MRI features heavily on a number of active surveillance protocols. This study looked at 86 men on active surveillance who had an mpMRI prior to 2013 to assess how lesions changed over time. Two blinded radiologists examined all the...

Visual-estimation (cognitive), image-fusion (software) and in-bore targeted prostate biopsy: is there an optimal approach?

The diagnostic superiority of multiparametric magnetic resonance imaging (mpMRI) prior to targeted and systematic prostate biopsy over systematic transrectal ultrasound-guided (TRUS) biopsy alone in the detection of clinically significant prostate cancer (csPCa) has been proven by multiple level 1 studies...

Indeterminate renal lesions – a pragmatic imaging approach

The incidence of renal cell carcinoma (RCC) in the UK has increased steadily over the last two decades, largely driven by the increasing use of abdominal imaging and the incidental detection of small renal lesions [1]. The majority of incidental...

The adrenals

Case 1 A 45-year-old man undergoes a CT of his abdomen to stage a newly diagnosed bowel malignancy. What does the scan show? What findings on a CT scan suggest an adrenal lesion is benign? If the CT scan is...

Evaluation of the learning curve for learning MRI-US fusion prostate biopsies

With the advent of one-stop prostate cancer diagnostic clinics, the findings of this study are of interest to readers who may be implementing MRI-US transrectal or transperineal fusion biopsies to their clinical practice. This prospective cohort study evaluated 779 consecutive...

Sexually transmitted infections

Case 1 A 27-year-old man presents to the clinic with multiple asymptomatic penile lesions. 1. What is the diagnosis? 2. What are the likely pathogens which cause these lesions? 3. What treatment options are available to treat these lesions? 4....

Bladder urothelial neoplasms in children

Urothelial bladder neoplasms are rare in children, occurring in 0.1-0.4% of the population before the age of 20. There are no current paediatric guidelines to their management. This study retrospectively reviews the files of patients from three tertiary centres between...

Testicular masses – can the testis be spared?

The standard practice for testicular masses confirmed on ultrasound has been to offer an inguinal orchidectomy, on the presumption that the mass represents testicular cancer. The growing use of scrotal ultrasound for various indications has led to an increase in...

Penile cancer

Case 1 A 67-year-old man presents with a worsening red patch over the past three months. It looks velvety in some areas. What is the most likely diagnosis? What are the risk factors? How do you classify this condition? How...

Comparison of pathological stage in patients treated with and without neoadjuvant chemotherapy for high-risk UTUC

High-risk upper tract urothelial carcinoma (UTUC) has been associated with poor survival outcomes. The authors evaluated the role of neoadjuvant chemotherapy in high-risk cases prior to radical nephroureterectomy (RNU) in terms of pathological stage of the final surgical specimen. A...
