Retroperitoneal cysts (RCs) are rare. They are composed of both epithelial and mesothelial tissues, and those without an epithelial lining in the wall are called pseudocysts. Most retroperitoneal pseudocysts are pancreatic in origin, and nonpancreatic pseudocysts are very rarely reported.We report a case of large cystic lesion adjacent to the left kidney in a 25 years old man. He presented with 2 and half years history of gradual swelling of left upper abdomen. Abdominal ultrasonography and CT scan showed a large unilocular cystic mass in left side of the abdomen, which was attached with the lower pole of the left kidney. The cystic mass was excised laparoscopically. Histology showed a fibrous wall without epithelial lining thus confirming the diagnosis of a nonpancreatic pseudocyst.

Abstract Background Mucinous cystadenoma (MC) of the kidney is exceedingly rare. We found 22 similar cases in the literature. These masses are underdiagnosed due to radiologic similarities with simple renal cysts. Case presentation A 66-year-old man with a previous history of hypertension and anxiety was referred to our tertiary clinic with left flank pain. Ultrasound revealed a 60 mm-sized, complex cystic mass with irregular septa in the lower pole of the left kidney (different from last year's sonographic findings of a simple benign cyst with delicate septa). CT scan showed the same results plus calcification. Due to suspected renal cell carcinoma, a radical nephrectomy was performed. Postoperative histopathologic examination revealed a cyst lined by a single layer of columnar mucin-producing cells with small foci of pseudo-stratification, consistent with the MC’s diagnosis. The first follow-up visit showed normal blood pressure without medication and no flank pain and anxiety after a month. Conclusion It is quite challenging to distinguish the primary MC of the kidney from a simple renal cyst based on clinical and imaging findings. The radiologic features of these entities overlap significantly. Thus, complex renal cyst and renal cysts with mural nodules should be followed closely to detect malignancy earlier.

Abstract We present an interesting case of a 70-year-old female who presented with haematuria on the suspected cancer pathway. Renal ultrasound showed a vascular renal mass on her right kidney measuring 8x7cm with an unremarkable left kidney. She underwent a laparoscopic radical nephrectomy following confirmation of an 8cm renal mass in the right kidney on the contrasted staging CT scan with a repeat review at the multidisciplinary meeting. Post-operatively a subsequent review of the pre-operative CT and ultrasound scan, showed an incidental large left(contralateral) upper quadrant retroperitoneal fatty mass sized 15x10cm, displacing the stomach and spleen. Further investigation in the form of an MRI Abdomen excluded features of a liposarcoma, resulting in the diagnosis of a large retroperitoneal lipoma. This case highlights the significance of selective attention in imaging interpretation. We believe this to be a prime example of the level of meticulousness required as fat-rich tissues have low attenuation on CT-scans, which can be easily missed out. A cautious multi-clinician interpretation of scans should be performed to avoid missing potentially sinister pathology which would impact patient care dramatically. This case has led to more thorough review of future pre-operative imaging by the operating surgical team.

To determine whether reduced renal mass in the newborn results in acceleration of normal renal development, the response to unilateral nephrectomy (N) before 36 h of age was compared with sham-operated (S) guinea pigs during the period of most rapid nephron maturation. Studies were performed at 7-13 days (group I) and 19-25 days (group II). Mean arterial blood pressure (AP), left kidney glomerular filtration rate (LKGFR), and urine sodium excretion (UNaV) were measured. Superficial single nephron GFR (sSNGFR) and proximal fractional water reabsorption (FRH2O) were measured by micropuncture, and the number of glomeruli (NG) was determined by India ink perfusion. In view of the susceptibility of the neonate to extracellular fluid loss, groups I and II were plasma infused to maintain euvolemia and group II was compared with 19- to 25-day-old hydropenic animals (group III). Increase in body weight with age was unaffected by neonatal N. In group IN, the compensatory increase in sSNGFR was greater than SNGFR for deeper nephrons, which normally contribute most to GFR at this age. In group IIN there was an 80% adaptive increase in LKGFR that could not be entirely explained by the rise in SNGFR. Since NG in group IIN was greater than in group IIS and similar to that in adulthood, the enhanced adaptation in LKGFR in group IIN may be due in part to earlier recruitment of a population of underperfused glomeruli. FRH2O did not change significantly with age and did not differ in N and S groups. Animals in group III developed a rise in hematocrit during the experiment, and AP, LKGFR, and UNaV were lower in group IIIN than in group IIN. It is concluded that following N at birth, the sequence of renal functional maturation is accelerated while glomerulotubular balance is preserved. As a result of these adaptative changes, homeostasis is maintained and body growth proceeds without impairment.

Abstract A 69-year-old woman presented with a large left retroperitoneal suprarenal mass. Radical resection of the left kidney and the mass revealed a cystic adrenal tumor with a weight of 1500 g. Histologic examination showed that the cyst was composed mostly of partially organized clotted blood. The periphery of the mass consisted of a thin rim of cortical and medullary adrenal tissue with superimposed granulomatous chronic inflammation. The infectious nature of the process was manifested by the scattered intracellular and extracellular Leishmania amastigotes that were found throughout the lesion. The differential diagnosis of cystic adrenal masses and the unusual presentation of visceral leishmaniasis are discussed in this context.
