24 Possible Causes for Abdominal Mass, Abnormal Corticomedullary Differentiation

  • Hydronephrosis

    A 34-year-old woman presented with progressive left abdominal pain and rebound abdominal mass at the left lower quadrant for 1 month.[ncbi.nlm.nih.gov] Perinephric urinoma Keyhole sign Loss of renal parenchyma, as suggested by: (i) cortical thinning, (ii) poor corticomedullary differentiation, (iii) increased renal echogenicity[indianpediatrics.net] Common symptoms include: Flank pain Abdominal mass, especially in children Nausea and vomiting Urinary tract infection (UTI) Fever Painful urination (dysuria) Increased urinary[nlm.nih.gov]

  • Cystic Kidney

    A blocked kidney may have a similar appearance on ultrasound, and tumors are another possibility for asymptomatic abdominal masses.[nationwidechildrens.org] Kidney size is either normal or reduced in MCKD, and ultrasound demonstrates increased echogenicity, loss of corticomedullary differentiation, and medullary cysts ( Figure[renalandurologynews.com] […] increased size of kidneys, a bright echotexture (hyperechogenicity) and a loss of the normal corticomedullary differentiation.[jmg.bmj.com]

  • Renal Abscess

  • Congenital Hydronephrosis

    […] distension and palpable abdominal mass, for 10 days before admission.[kjp.or.kr] Perinephric urinoma Keyhole sign Loss of renal parenchyma, as suggested by: (i) cortical thinning, (ii) poor corticomedullary differentiation, (iii) increased renal echogenicity[indianpediatrics.net] Some infants with severe hydronephrosis may have abdominal distention or palpable abdominal mass.[gaurology.com]

  • Tumor Lysis Syndrome

    A 23-year-old woman was admitted to our hospital with worsening abdominal distention and a lower abdominal mass.[ncbi.nlm.nih.gov] The ultrasonographic image on the right shows a kidney from a patient with the tumor lysis syndrome, in which there is loss of the normal corticomedullary differentiation[ncbi.nlm.nih.gov] In patient without known malignancy, CT of abdomen/pelvis and chest may be warranted if there’s clinical examination of lymphadenopathy and intra-abdominal mass, however,[clinicaladvisor.com]

  • Renal Transplant Rejection

    Mass effect from perinephric fluid can result in hydronephrosis; or edema of the leg, abdominal wall, labia or scrotum (Figure 2). 4 Perinephric abscesses are uncommon, but[appliedradiology.com] Renal parenchyma The superficial location of the renal transplant allows for normal corticomedullary differentiation of the renal parenchyma, with the medullary pyramids being[appliedradiology.com] Unfortunately, the sonographic appearance of many diffuse renal parenchymal abnormalities is nonspecific, including acute tubular necrosis (ATN), acute or chronic rejection[appliedradiology.com]

  • Medullary Cystic Kidney Disease

    Many of these kidneys are identified in utero on ultrasound or clinically as an intra-abdominal mass.[urologyweb.com] Histological examination usually reveals abnormalities in ductal differentiation and minimal corticomedullary differentiation.[lecturio.com] Kidney size is either normal or reduced in MCKD, and ultrasound demonstrates increased echogenicity, loss of corticomedullary differentiation, and medullary cysts (Figure[renalandurologynews.com]

  • Renal Arteriovenous Fistula

    Small renal masses on abdominal imaging studies performed for other symptoms are becoming more common.[emedicine.medscape.com] Apart from graft swelling or enlargement, there can be obscured corticomedullary differentiation, decreased echogenicity, and scattered heterogenous areas of increased echogenicity[cjasn.asnjournals.org] The left ventricular mass, calculated following the equation by Devereux, was 220.3 g, then normalised for body surface area—left ventricular mass index—121 g/m 2.[nature.com]
