The frequency of gallstone disease is 0.79%. Nonhaemolytic type of cholelithiasis is more common than haemolytic type in this region. Presence of cysticercus in the gallbladder wall in one case was an unexpected finding.

High-resolution sonography is a noninvasive and nonionizing imaging modality that plays an important role in establishing the diagnosis of cysticercosis.

IntroductionAutosomal dominant polycystic kidney disease is an inherited disorder that is characterized by the development and growth of cysts in the kidneys and other organs. Urinary protein excretion is usually less than 1 g/24 hours in autosomal dominant polycystic kidney disease, and an association of nephrotic syndrome with this condition is considered rare. There are only anecdotal case reports of autosomal dominant polycystic kidney disease associated with nephrotic syndrome, with focal segmental glomerulosclerosis being the most commonly reported histopathological diagnosis. Nephrotic-range proteinuria in the presence of autosomal dominant polycystic kidney disease, with or without an accompanying decline in renal function, should be investigated by open renal biopsy to exclude coexisting glomerular disease. To the best of our knowledge, this is the first case of autosomal dominant polycystic kidney disease with histologically proven diffuse proliferative glomerulonephritis presenting with nephrotic-range proteinuria. No other reports of this could be found in a global electronic search of the literature.Case presentationWe report the case of a 35-year-old Indo-Aryan man with autosomal dominant polycystic kidney disease associated with nephrotic syndrome and a concomitant decline in his glomerular filtration rate. Open renal biopsy revealed diffuse proliferative glomerulonephritis. An accurate diagnosis enabled us to manage him conservatively with a successful outcome, without the use of corticosteroid which is the standard treatment and the drug most commonly used to treat nephrotic syndrome empirically.ConclusionDespite the reluctance of physicians to carry out a renal biopsy on patients with autosomal dominant polycystic kidney disease, our case supports the idea that renal biopsy is needed in patients with polycystic kidney disease with nephrotic-range proteinuria to make an accurate diagnosis. It also illustrates the importance of open renal biopsy in planning appropriate treatment for patients with autosomal dominant polycystic kidney disease with nephrotic-range proteinuria. The treatment for various histological subtypes leading to nephrotic syndrome is different, and in this modern era we should practice evidence-based medicine and should avoid empirical therapy with its associated adverse effects.

Unilateral and segmental cystic disease is a rare cystic disease of the kidney. Except for its unilaterality, it resembles autosomal dominant polycystic kidney disease on gross and histological examination. It also lacks genetic background and progressive deterioration of renal function. Only a small number of unilateral and segmental cystic disease of the kidney cases have been reported to date. The present case is a report of a 69-year-old man who had a large multicystic mass involving the lower and middle part of the right kidney with normal residual renal parenchyma at the upper pole. The left kidney was entirely normal. All the laboratory tests were within normal limits. Right nephrectomy was performed because of a strong suspicion of malignancy.
