Kaposi's sarcoma involving a transplanted kidney: CT findings.

Kaposi's sarcoma involving a transplanted kidney, ureter and urinary bladder: ultrasound and CT findings.

“…In two cases, the tumours involved the allograft parenchyma, but the lesions were not detected by ultrasound or CT [2,3]. In the other case, CT showed an in®ltrating homogeneous soft tissue attenuation lesion affecting the allograft hilum and sinus [4]. Our case differed from the previously reported ones in that multiple Kaposi's sarcomas occurred in the transplanted renal pelvis, ureter and bladder, seen as well de®ned enhancing nodules on CT.…”

“…To the best of our knowledge, only three cases of Kaposi's sarcoma involving a transplanted kidney have been reported [2±4]. The CT ®ndings of Kaposi's sarcoma involving a transplanted kidney have been reported only once before [4]. We report the imaging ®ndings in a renal transplant recipient who developed Kaposi's sarcoma affecting the allograft renal pelvis, ureter and urinary bladder.…”

Infiltrating Kaposi sarcoma presenting as acute kidney injury: An unexpected consequence of deliberate hepatitis C–positive organ transplantation

“…Kaposi sarcoma directly involving the kidney allograft is extremely rare with only seven previously reported cases 12,13,34‐38 (Table 1). In two of these cases, neoplastic parenchymal invasion contributed directly to allograft dysfunction 12,13 .…”

Helical CT in Renal Transplantation: Normal Findings and Early and Late Complications

“…Kaposi sarcoma accounts for 6% of tumors in patients who have undergone transplantation (24). Renal allograft involvement by Kaposi sarcoma is rare.…”
