  • Primary mucinous adenocarcinoma of the renal pelvis is extremely rare, with only ~100 cases reported till now. (eurekamag.com)
  • We report a case of primary mucinous adenocarcinoma of the renal pelvis misdiagnosed as ureteropelvic junction stenosis with a renal pelvis stone. (eurekamag.com)
  • Abdominal computed tomography showed a hyperdense mass with 2.62 × 5.70 cm size in the right renal pelvis and severe hydronephrosis and cortical thinning. (eurekamag.com)
  • Primary mucinous adenocarcinomas of the renal pelvis are extremely rare, and most are diagnosed via post-operative analysis of resected specimens. (eurekamag.com)
  • Urothelial carcinomas can also occur in the renal pelvis, ureter, or urethra but their occurrence is far less common than in the urinary bladder. (hindawi.com)
  • It appeared to be encapsulated along its free margin, but elsewhere, seemed to merge with the dilated renal pelvis and with the parenchyma which was compressed to a thin peripheral rim. (scielo.org)
  • The tumour infiltrated the surrounding fibrous capsule and extended to involve the muscularis propria of the renal pelvis. (scielo.org)
  • adrenal
  • Follow-up imaging studies 5 and 8 months after nephrectomy were unremarkable, but imaging 11 months after nephrectomy demonstrated multiple small lung nodules, an exophytic left renal mass, and a left adrenal mass. (urotoday.com)
  • On review of the multiplanar image reformats, there was no demonstrable fat plane between the renal lesions and the lateral limbs of the adrenal glands (figure 2). (eurorad.org)
  • These appearances were thought to represent incidental congenital adrenal-renal fusion. (eurorad.org)
  • Adrenal-renal fusion is considered to be caused by failure of the retroperitoneal mesenchymal cells to stimulate capsule formation . (eurorad.org)
  • The aetiology of adrenal-renal fusion is unknown, but is likely to be a local event around 52 days post-conception, due to the absence of other congenital abnormalities . (eurorad.org)
  • While isolated adrenal-renal fusion is a benign diagnosis with no clinical implications, there are several case reports in which the radiological appearances have been misinterpreted, particularly when there is a concurrent adrenal lesion, resulting in unnecessary surgery. (eurorad.org)
  • Post-operatively, when the en-bloc specimen was reviewed, adrenal-renal fusion and adrenal adenoma were diagnosed . (eurorad.org)
  • based on the lack of an avascular plane between the renal and adrenal capsule , which negated the need for a larger resection. (eurorad.org)
  • Adrenal-renal fusion is considered difficult to diagnose radiologically, and the imaging appearances described in the existing literature have been observed retrospectively. (eurorad.org)
  • The routine use of thin-slice CT image acquisition and multiplanar reformats in the last 10-15 years allows better detection of an absent fat plane, although this finding is not specific for adrenal-renal fusion and in unilateral cases is it difficult to exclude an invasive renal, adrenal or retroperitoneal lesion. (eurorad.org)
  • We herein report a case of adrenal EMH, presenting as a large right adrenal mass with the imaging features of MRI. (dict.cn)
  • Laparoscopic renal and adrenal surgery in obese patients: comparison to open surgery. (springer.com)
  • tumour
  • Immunohistochemical staining of the specimen showed a highly specific cluster of differentiation CD 99, thus confirming the diagnosis of a primitive neuroectodermal tumour. (duhnnae.com)
  • ConclusionIt is important that a renal primitive neuroectodermal tumour be considered, particularly in young patients with a renal mass and extensive thrombus. (duhnnae.com)
  • About 200 cases of the tumour have been reported so far and it has the ensuing morphological features: large numbers of small confluent irregular nests of bland-appearing, closely packed, haphazardly arranged, and poorly defined urothelial cells infiltrating the lamina propria and the muscularis propria. (hindawi.com)
  • The specimen weighed 1593g and, on sectioning, revealed a 15 cm firm, tan tumour with a whorled cut-surface showing areas of infarction. (scielo.org)
  • Histology ( Fig. 2 ) revealed a partly encapsulated tumour composed of intersecting fascicles of spindle shaped cells with pleomorphic vesicular nuclei that varied from blunt ended and cigar shaped to large and irregular. (scielo.org)
  • A better prognosis is associated with tumour size below 5 cm, low histologic grade, absence of lymph node metastases and radical surgery (5) which is the only form of treatment as adjunctive therapy does not alter the clinical course. (scielo.org)
  • lesion
  • Biopsy specimens obtained from the top of the lesion showed no specific finding. (ovid.com)
  • We describe a case of renal leiomyosarcoma seen at the University Hospital of the West Indies and comment on important characteristics of this lesion. (scielo.org)
  • Biopsy
  • However, a precise diagnosis using biopsy specimens was not made for 1 year, although the examinations were performed every 6 months. (ovid.com)
  • Therefore, endoscopic examination and the evaluation of biopsy specimens were repeated every 6 months. (ovid.com)

  • tumours
  • Leiomyosarcomas are the most common of the primary renal sarcomas which account for less than 1% of renal tumours in adults. (scielo.org)
  • They tend to be large, firm tan tumours, usually greater than 10 cm (3) and their classic histologic features were present in this case. (scielo.org)
  • retrospective
  • A retrospective analysis of our prospectively maintained institutional database on renal surgery since 1983 was performed. (auanet.org)
