이선규 대한영상의학회 1992 대한영상의학회지 Vol.28 No.2

CT findings of 19 kidneys in 12 patients with renal and perirenl non-Hodgkin's lymphoma were retrospectively reviewed to determine distinguishing characteristic and specific findings. CT manifestation of the renal nad perirenal lymphoma included multiple nodules in five kidneys (26.3%) trans-capsular infiltration in three kidneys (15.8%) trans-sinus infiltration in nine kidneys (52.6%) and crescentic lesion of low attenuation in the subcapsular area in five kidneys (26.3%) Retroperitoneal lymphadenopathy was evident in eleven patient(57.9%) Renal calyceal dilatation without renal pelvic dilatation (selective calycelal dilatation) was noted in three kidneys. Familiarity with these CT findings of renal and perirenal lymphoma may be helpful in the diagnosis and management of patient with non-Hodgkin's lymphoma.

Papillary Renal Cell Carcinoma in Transplanted Kidney and Xp11.2 Translocation/ Transcription Factor E3-Rearranged Renal Cell Carcinoma in the Native Kidney: A Case Report

Min Hye Kim,Kyeong Ah Kim,Jeong Woo Kim,Seok Young Lee,Jae Woong Choi 대한영상의학회 2024 대한영상의학회지 Vol.85 No.2

Concomitant renal cell carcinomas (RCC) of both native and allograft kidneys are extremely rare, and only a few cases have been reported in the available English literature. A particularly rare variant within the adult population is the Xp11.2 translocation/transcription factor E3 (TFE3)-rearranged RCC. Although few case reports of TFE3-rearranged RCC have been reported in children who underwent kidney transplantation (KT), no case of adults with TFE3-rearranged RCC following KT has been reported. Herein, we presented the radiological and pathological findings of a rare metachronous papillary RCC in the allograft kidney and TFE3-rearranged RCC in the native kidney. The TFE3-rearranged RCC in the native kidney exhibited slow expansion in size over five years. Radiologically, it appeared as a slightly enhanced, lobulated mass on contrast-enhanced CT. MRI revealed high signal intensity on T1-weighted images and low signal intensity on T2-weighted images.

전이성 신장암의 CT 및 초음파 소견

김승협 대한영상의학회 1995 대한영상의학회지 Vol.32 No.2

Purpose: To evaluated imaging characteristics of metastatic renal tumors in CT and US. Materials and methods:Renal metastases were diagnosed in 25 patients by surgery (n=2), US-guided biopsy (n=15), or follow-up CT (n=8).The primary tumors metastasized to kidney were lung cancer (n=11), adenoid cystic carcinoma (n=3), stomach cancer(n=2), and choriocarcinoma (n=2). Twelve cases invloved one kidney and 13 invloved both kidneys. CT was performedin all 25 patients while US was done in 14. We analysed CT findings in respect to number, size, shape, exophyticdegree, margin, and degree and homogeneity of the contrast enahncement of the lesion ; US findings in regand toechogenicity and homogeneity of the lesion. Results: The average number of the lesions per patient seen on CT wasthree; average diameter of the lesion was 3.6 cm; and 75% (57/76) of all tumors had exophytic degree of 0%. Thecharacteristic CT findings of metastatic renal tumors were round shape (52/76), ill-defined margin (54/76), andpoor (76/76) and inhomogeneous (45/76) contrast enhancement. The echogenicity of the tumors were homogeneous(11/18) and isoechoic (10/18) on US. Conclusion: Metastatic renal tumors had a tendency of multiple, small,ill-marginated, and less-exophytic nature on CT, and homogeneous, isoechoic appearance on US. The familiarity withthe constellation of CT and US findings of renal metastasis described may be helpful in making a correctdiagnosis.

Mucinous Tubular and Spindle Cell Carcinoma of the Kidney with Aggressive Behavior: An Unusual Renal Epithelial Neoplasm - A Case Report-

이지혜,오미혜,조현득,김영식 대한병리학회 2010 Journal of Pathology and Translational Medicine Vol.44 No.2

Mucinous tubular and spindle cell carcinoma is a rare low-grade renal cell carcinoma, which was first described as a new entity in the World Health Organization 2004 classification. We report here on a case of this tumor with very unusual aggressive behavior. A 73-year-old man presented with gross hematuria. A computed tomography scan demonstrated a 5 cm sized low density mass in the left kidney. The radical nephrectomy specimen grossly showed a well demarcated tumor confined to the renal parenchyma. Histologically, the tumor consisted of elongated tubules or trabeculae of oval to cuboidal cells with a low nuclear grade, and these tubules/trabeculae were separated by abundant acidic mucinous stroma. In some areas, spindle cell components were mixed with parallel tubules. Neither significant atypia nor mitosis was seen. The patient developed multiple metastatic pulmonary nodules 2 months later. Four months after the surgery, the left supraclavicular, right hilar and right subcarinal lymph nodes were also enlarged by metastasis. The patient died of respiratory failure 13 months after the operation.

신세포암에 있어서 신장 윤곽 융기에 관한 방사선학적 고찰

이병철,김종철 충남대학교 의과대학 지역사회의학연구소 1996 충남의대잡지 Vol.23 No.2

We analyzed radiologic findings of 34 renal cell carcinomas (RCCs) of excretory urography, angiography, sonogram, CT, or MRI, with emphasis on renal contour bulging. Renal contour bulging was noted in all cases including two small hyperechoic RCCs (stage I) of less than 3cm in diameter on ultrasonography. The border of contour bulging tended to be smooth (9/10 = 90%) and symmetric (8/10 = 80%) in stage I RCCs, but irregular (13/16 = 81%) and asymmetric (9/16 = 56%) in stage IV RCCs. The diameter ratio of the bulging portion of the tumor to the tumor as a whole did not show any statistically significant difference to the stage of RCCs. Radiologic findings of pelvicaliceal involvement of RCCs (hydrocalyx, hydronephrosis, non-opacification of the affected kidney, etc.) were demonstrated in seven cases (21%), and all these seven RCCs were longer than 5cm in diameter and six of seven RCCs belnged to stage IV. All five cases less than 5cm in diameter were of stage I, whereas all three RCCs greater than 15cm were of stage IV. Only two patients (6%) of stage IlIc & IV showed impairment of renal function on the basis of increased serum creatinine level and clinical findings. Renal contour bulging adjacent to a renal solid or complex tumor without dilatation of pelvicaliceal system or impairment of renal function can be used as one of useful criteria to diagnose and stage RCCs and differentiate them from uroepithelial tumors in adult kidneys.

CT and MRI Findings of Angiomyolipoma with Epithelial Cysts of the Kidney: A Case Report

여동명,정동진,김태정,이인규,한성태,이재문 대한영상의학회 2010 대한영상의학회지 Vol.63 No.2

Angiomyolipoma with epithelial cysts (AMLEC) or cystic angiomyolipoma has been recently described as a distinct cystic variant of angiomyolipoma. Although angiomyolipoma (AML) is usually composed of adipose, vascular, and muscular tissue lacking an epithelial element, AMLEC contains an epithelial component in the form of gross or microscopic cysts. To date, the radiologic appearance of AMLEC has been demonstrated in only one case report, as a solid mass containing a tiny cystic focus. This report shows another imaging feature of AMLEC, which presents as a multiloculated cystic mass without a visible solid portion on CT and MRI.

Mucinous tubular and spindle cell carcinoma of the kidney has been recognized as a distinct entity in the 2004 World Health Organization classification of adult renal tumors; it constitutes less than 1% of all the renal neoplasm. Radiological features of mucinous tubular and spindle cell carcinoma have been published in a small number of cases. This case report presents a case of mucinous tubular and spindle cell carcinoma, including CT and MR finding. 점액성 세관 방추세포 신장암종은 최근 세계 보건 기구(World Health Organization) 2004년 신세포암 분류에 포함된 질병으로 세관 구조, 방추형 세포, 점액성 기질로 구성되어 있다. 이는 신장암종의 1% 미만을 차지하는 드문 질병으로 아직 영상소견이 확립되지 않았으며 적은 수의 보고가 있다. 본 증례는 점액성 세관 방추세포 신장암종 1예의 CT 및 MR 소견을 보고하고자 한다.

Primary adenocarcinoma with yolk sac differentiation in the transplant ureter and salvage of the transplant kidney: a rare case report

Bharath Nagarajan Kumar,Abhishek Kumar Shukla,Prerna Guleria,Bhaskar Datt,Sudeep Prakash,Arun Raja Vairam 대한이식학회 2023 Korean Journal of Transplantation Vol.37 No.2

Renal transplant recipients are prone to a high risk of subsequent upper tract urothelial carcinoma, occurring in both native and transplant ureters. We report a rare case of adenocarcinoma with yolk sac differentiation of the transplant ureter, which was managed successfully with transplant ureterectomy and pyelovesicostomy, thereby salvaging the functioning transplant kidney.
