Glomerulocystic kidney disease presenting as acute
renal failure in an adult patient
The diagnosis of glomerulocystic kidney disease (GCKD)
in adults is usually an incidental finding during the evalua-
tion of other working diagnoses. Hereby we report the case
of a 55-year-old woman admitted for an elective second
prosthetic mitral valve replacement for rheumatic mitral
valvulopathy who presented acute renal failure (ARF).
Four months before, when a diagnosis of granuloma
annulare was made, her plasma creatinine was 1.8 mg/dl
and urinanalysis showed haematuria without proteinuria.
Her father, aged 60 years, had died of chronic renal failure
of unknown cause. Twenty days before hospital admis-
sion she had pneumonia and was treated with penicillin
and diclofenac for 10 days. She was regularly taking
atenolol and hydroclorthiazide. On admission she was
normotensive. Urinary volume was 1000 ml/day.
Laboratory tests showed plasma creatinine ¼ 6 mg/dl, blood
urea nitrogen ¼ 90 mg/dl, plasma sodium ¼ 140 mEq/l,
plasma potassium ¼ 5.2 mEq/l, ionic calcium ¼ 4.4 mg/dl,
phosphate ¼ 10 mg/dl, haemoglobin ¼ 9.6 g/l, leukocytes ¼
and platelets ¼ 120 000/mm
. Urinalysis showed
pH ¼ 6, gravity ¼1014, leukocytes ¼144 000/ml, red blood
cells ¼ 145 000/ml. Proteinuria was 1.6 g/24 h. Urine culture
was negative. Ultrasonography showed normal-sized
kidneys with mild hyperechogenicity and a cortical cyst of
2.4 cm in the left kidney. The patient’s renal function
worsened and she required haemodialysis for 2 weeks.
Renal biopsy showed marked dilatation of Bowman’s
space in 40% of glomeruli with the correspondent glomerular
tufts collapsed (see Figure 1). No periglomerular fibrosis
was found. Dilated tubuli with flattened epithelial cells
or with regenerative changes were seen in some areas.
The arteries had no alterations. The final diagnosis was
GCKD plus regenerating acute tubular necrosis. In the
40th hospital day she was discharged, having undergone
uneventful heart surgery on the 20th hospital day, with
plasma creatinine ¼ 2.5 mg/dl. Thirty days after discharge,
she maintained the same creatinine and microscopic
GCDK is more often described in infants and young
children than in adults. Nowadays GCDK is categorized
into three groups according its clinical presentation: (i) spo-
radic or heritable non-syndromal forms found in children or
adults; (ii) heritable syndromal forms; and (iii) glomerular
cysts found in dysplasic kidneys [1]. The sporadic form
of GCKD associated with other renal diseases has been
designated acquired [2,3]. Although hypercalcaemic ARF
had been reported in association with annular granuloma,
our patient did not have hypercalcemia that points to
the presence of annular granuloma be incidental [4]. Her
father having had renal failure suggests a heritable
non-syndromal form of GCKD, where urinanalysis can be
normal or show non-nephrotic proteinuria and haematuria
as in the case of our patient. Ultrasonography can show
characteristic findings, such as a hypoechoic cortical rim
or less characteristic patterns, such as exclusive cortical
cysts, loss of corticomedullary differentiation, hypoplastic
or diffusely echogenic kidneys [5]. The patient’s ultra-
sound showed mild cortical hyperechogenicity and only a
cortical cyst. Although there was no consensus on the
histological criteria to define GCKD, Berstein’s definition
is the most strict: presence of dilatation of Bowman’s space
of two to three times in the plane of section in at least
5% of the glomeruli [1]. Our patient certainly fits this
definition: 40% of her glomeruli showed marked dilatation
of Bowman’s space. The finding of superimposed acute
tubular necrosis can explain the worsening of renal function
and subsequent partial recovery in our patient. ARF was
attributed to the prolonged use of diclofenac. The reported
case points to the importance of performing renal biopsy
in ARF of uncertain cause and, to the best of our
knowledge, this is the first report of GCKD associated with
acute tubular necrosis.

  • [Show abstract] [Hide abstract] ABSTRACT: Glomerular cysts, defined as Bowman space dilatation greater than 2 to 3 times normal size, are found in disorders of diverse etiology and with a spectrum of clinical manifestations. The term glomerulocystic kidney (GCK) refers to a kidney with greater than 5% cystic glomeruli. Although usually a disease of the young, GCK also occurs in adults. To assess the recent molecular genetics of GCK, review our files, revisit the literature, and perform in silico experiments. We retrieved 20 cases from our files and identified more than 230 cases published in the literature under several designations. Although GCK is at least in part a variant of autosomal dominant or recessive polycystic kidney disease (PKD), linkage analysis has excluded PKD-associated gene mutations in many cases of GCK. A subtype of familial GCK, presenting with cystic kidneys, hyperuricemia, and isosthenuria is due to uromodullin mutations. In addition, the familial hypoplastic variant of GCK that is associated with diabetes is caused by mutations in TCF2, the gene encoding hepatocyte nuclear factor-1beta. The term GCK disease (GCKD) should be reserved for the latter molecularly recognized/inherited subtypes of GCK (not to include PKD). Review of our cases, the literature, and our in silico analysis of the overlapping genetic entities integrates established molecular-genetic functions into a proposed model of glomerulocystogenesis; a classification scheme emerged that (1) emphasizes the clinical significance of glomerular cysts, (2) provides a pertinent differential diagnosis, and (3) suggests screening for probable mutations.

  • [Show abstract] [Hide abstract] ABSTRACT: Cystic renal lesions are commonly encountered in abdominal imaging. Although most cystic renal lesions are benign simple cysts, complex renal cysts, infectious cystic renal disease, and multifocal cystic renal disease are also common phenomena. The Bosniak classification system provides a useful means of categorizing cystic renal lesions but places less emphasis on their underlying pathophysiology. Cystic renal diseases can be categorized as focal, multifocal, or infectious lesions. Diseases that manifest with focal lesions, such as cystic renal cell carcinoma, mixed epithelial and stromal tumor, and cystic nephroma, are often difficult to differentiate but have differing implications for follow-up after resection. Multifocal cystic renal lesions can be categorized as acquired or heritable. Acquired entities, such as glomerulocystic kidney disease, lithium-induced nephrotoxicity, acquired cystic kidney disease, multicystic dysplastic kidney, and localized cystic renal disease, often have distinct imaging and clinical features that allow definitive diagnosis. Heritable diseases, such as autosomal dominant polycystic kidney disease, von Hippel-Lindau disease, and tuberous sclerosis, are usually easily identified and have various implications for patient management. Infectious diseases have varied imaging appearances, and the possibility of infection must not be overlooked when assessing a cystic renal lesion. A thorough understanding of the spectrum of cystic renal disease will allow the radiologist to make a more specific diagnosis and provide the clinician with optimal recommendations for further diagnostic testing and follow-up imaging.

  • [Show abstract] [Hide abstract] ABSTRACT: The patient was a 28-year-old man with chronic kidney disease in stage 5 and in the course of chronic membranoroliferative glomerulonephritis. The patient was treated for a period of 2 months using peritoneal dialysis. In September 2014, he had a kidney transplant from a deceased donor. Four months after transplantation the patient was admitted to the hospital for a protocol biopsy. His creatinine was 1.5 mg/dL and urea was 59 mg/dL, urinalysis was normal in blood count with a normocytic anemia-hemoglobin level of 7.8 mmol/L. We obtained a histopathological evaluation of the cortex and medulla of the kidney. Glomeruli dilatation of Bowman space with reduced glomerular capillary tufts was found in the section. Histopathological evaluation indicated gromerulocystic kidney disease in a transplanted kidney.
