A 55-year-old woman, diagnosed with a renal mass by abdominal ultrasonography (USG) in an external medical centre, presented to our hospital. The medical history was unremarkable except for diabetes mellitus and hypertension. The haemogram and urine tests were normal. The only pathology revealed in routine biochemistry tests was increased glucose level (164 mg/dL). The repeat USG performed in our hospital revealed a solid hypoechoic mass lesion approximately 4 cm in diameter closely adjacent to the right kidney...

OBJECTIVES: Malnutrition and wasting predict clinical outcomes in children with severe chronic illness. Objectively calculated malnutrition in children with end-stage organ failure has not been well studied. This analysis compares children with kidney, liver or intestine failure to healthy controls to quantitate the disparity in muscle and fat stores. METHODS: Children younger than age 19 with end stage liver, kidney or intestine failure and with pre-transplant computed tomography (CT) imaging were selected from the transplant database...

BACKGROUND: This is a unique case of neuropraxia of femoral nerve seen after resection of retroperitoneal liposarcoma which has not been reported before in the literature. INTRODUCTION: Neuropraxia, a transient paralysis due to blockage of nerve conduction, commonly associated with athletes and orthopedic procedures, has not been previously reported as a complication following resection of retroperitoneal sarcoma. CASE: This is an 81-year-old female who, on CT for evaluation of her atherosclerosis, was found to have an incidental right-sided retroperitoneal mass extending from the right renal capsule inferiorly through the inguinal canal...

Computed tomography (CT) remains the first-line imaging test for the characterisation of renal masses; however, CT has inherent limitations, which if unrecognised, may result in errors. The purpose of this manuscript is to present 10 pitfalls in the CT evaluation of solid renal masses. Thin section non-contrast enhanced CT (NECT) is required to confirm the presence of macroscopic fat and diagnosis of angiomyolipoma (AML). Renal cell carcinoma (RCC) can mimic renal cysts at NECT when measuring <20 HU, but are usually heterogeneous with irregular margins...

Objective: To study the etiological, clinical, radiological, diagnostic, therapeutic, and prognostic manifestations of exogenous lipoid pneumonia (ELP), and therefore to improve the diagnosis and treatment of this disease. Methods: The clinical data of 12 cases of ELP confirmed by pathology were retrospectively analyzed. Results: The patients consisted of 9 males and 3 females, with an average age of 73.8 years (range, 44 to 100 years). The underlying diseases were variable, including diseases affecting the general condition (multiple organ failure, chronic heart and renal insufficiency, pemphigoid, etc) and conditions with increased risk of aspiration (sequelae of cerebrovascular disease, Alzheimer's disease, advanced stage of nasopharyngeal carcinoma, paralytic ileus, etc)...

OBJECTIVE: It was reported that a metabolic syndrome affected the remaining renal function after living donor nephrectomy. However, the measurement of waist circumference is unclear because it cannot distinguish between visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT). We investigate the clinical correlation between body adipose tissue and renal function recovery after living donor nephrectomy. METHODS: From July 2013 to February 2015, 75 living kidney donors were enrolled...

REVIEW

Most renal lesions replace the renal parenchyma as a focal space-occupying mass with borders distinguishing the mass from normal parenchyma. However, some renal lesions exhibit interstitial infiltration-a process that permeates the renal parenchyma by using the normal renal architecture for growth. These infiltrative lesions frequently show nonspecific patterns that lead to little or no contour deformity and have ill-defined borders on CT, making detection and diagnosis challenging. The purpose of this pictorial essay is to describe the CT imaging findings of various conditions that may manifest as infiltrative renal lesions...

BACKGROUND: Primary tumors in the presacral (retrorectal) space are extremely rare in adults, with an estimated incidence of 0.0025 to 0.014 in large referral centers. Congenital varieties are most common and comprise two thirds of these tumors. Primary retroperitoneal sarcomas in the pelvic region are extremely rare. We report the ultrasound and the corresponding Computed Tomography (CT) features of a rare presacral fibrosarcoma in an adult woman, in whom the diagnosis was confirmed by a CT-guided biopsy...

BACKGROUND: Tyrosine kinase inhibitors are the first line standard of care for treatment of metastatic renal cell carcinoma (RCC). Accurate response assessment in the setting of antiangiogenic therapies remains suboptimal as standard size-related response criteria do not necessarily accurately reflect clinical benefit, as they may be less pronounced or occur later in therapy than devascularisation. The challenge for imaging is providing timely assessment of disease status allowing therapies to be tailored to ensure ongoing clinical benefit...

Myxomas are mesenchymal tumors commonly found in the heart and skin. Renal myxomas are rare, having only been documented 14 times. Our case is a 55-year-old woman who presented to our clinic after a right renal mass was incidentally found on CT. Evaluation with MRI showed a mass that appeared to arise from the supero-medial cortex of the right kidney. As the imaging was concerning for renal cell carcinoma, the patient underwent a partial nephrectomy. Microscopic examination showed a well-circumscribed mass with polygonal to spindle-shaped cells in a granular eosinophilic cytoplasm...

Large cell neuroendocrine carcinoma (LCNEC) of the urinary bladder are rare. We present a case of a 72-year-old man who presented with back pain and acute renal failure. Ultrasound showed a soft tissue mass in the base of the bladder causing bilateral ureteric obstruction. Subsequent biopsy of this mass demonstrated neuroendocrine carcinoma. He was commenced on neoadjuvant chemotherapy (carboplatin/etoposide) and proceeded to a radical cysto-prostatectomy. Histology revealed a LCNEC involving the bladder, T4a with invasion through to adipose tissue and posteriorly at perivesical resection margins...

BACKGROUND: In this prospective study, we aimed to assess the haemodynamic changes before and after haemodialysis (HD) in cardiac healthy subjects on chronic HD by imaging methods and endocrine markers of fluid balance. METHODS: Mid-regional pro-atrial natriuretic peptide (MR-proANP), N-terminal prohormone of brain natriuretic peptide (NT-proBNP), vasopressin (AVP) and copeptin (CT-proAVP), metanephrines and normetanephrines, renin and aldosterone, standard transthoracic echocardiography and diameter of vena cava inferior (VCID) were performed in 20 patients with end stage renal disease (CKD5D) before and after HD and were stratified in residual excretion (RE, less or more 0...

Urachal carcinoma is an extremely rare malignant tumor arising from the urachus in the fetus. We report a patient who developed urachal carcinoma 18 years after kidney transplantation. A 59-year-old man was admitted because of abdominal pain and massive ascites. He had undergone kidney transplantation 18 years earlier and had end-stage renal disease requiring dialysis. Abdominal CT showed massive ascites and an abdominal wall cystic mass separated from the peritoneal cavity. Hemodialysis was started, and paralytic ileus was diagnosed and treated...

Renal pseudotumour is a term coined to describe conditions of renal anatomic variants that simulate focal renal pathology like a tumour on ultrasonography. These include persistent fetal lobulation, hypertrophy of Bertin columns and dromedary humps. We report a case of a 30-year-old nulliparous woman who was managed in gynaecology clinic for menorrhagia and was subsequently referred to us for management of recurrent urinary tract infections. The clinical examination was normal and on ultrasound scan, she was found to have multiple enlarged heterogeneous solid masses in both kidneys with significantly increased vascularity, suspicious for neoplastic lesions...

BACKGROUND: Image guidance for spine pain control procedures, including epidural steroid injection, nerve root block, and facet block, can be performed with either computed tomography (CT) or conventional fluoroscopy. CT has the advantage of improved anatomic localization and use of air for contrast; however, there are concerns that CT leads to higher radiation dose and longer procedure time. OBJECTIVE: To evaluate procedure time and radiation dose for multiple types of spine pain control procedures performed under CT guidance...

PURPOSE: Papillary renal cell carcinoma (P-RCC) typically exhibits a homogeneous, solid hypovascular mass; P-RCC with a cystic appearance is atypical. Tubulocystic RCC (TC-RCC), a newly proposed entity for renal tumors in the 2016 WHO classification, and cystic papillary RCC, may yield similar imaging findings. Therefore, we investigated the incidence of papillary RCC with cystic changes and compared its CT and pathologic features to differentiate between two entities. METHODS: We retrospectively evaluated 26 consecutive patients diagnosed with P-RCC...

BACKGROUND: The ascending aorta is an uncommon site for non-infective thrombus. In non-aneurysmal and non-atherosclerotic vessels this condition becomes extremely rare, while it represents a source of potential cerebral and peripheral embolic events. Currently, there is no consensus in the guidelines on how to treat a free floating thrombus in ascending aorta, therefore we present our decision making process and therapeutic strategy. CASE PRESENTATION: A healthy 48-year-old man was hospital admitted with acute abdominal pain...
