Zusammenfassung

Wir präsentieren den seltenen Fall eines primären neuroendokrinen Tumors (NET) der Niere. Zur Kontrolle eines Nebennierenadenoms erfolgte bei einem 56-jährigen Patienten eine MRT des Abdomens, die als Zufallsbefund eine Raumforderung am linken Nierenoberpol verdächtig auf ein Nierenzellkarzinom zeigte. Nach Teilnephrektomie konnte histologisch ein 4,2 cm durchmessender NET diagnostiziert werden. Mittels DOTATATE-PET-CT wurde postoperativ ein extrarenaler Primärtumor ausgeschlossen. Ein primäres Auftreten eines NET im Urogenitaltrakt ist selten und in der Literatur in weniger als 100 Fällen beschrieben.

Abstract

This article presents a rare case of a primary neuroendocrine tumor (NET) of the kidney. Abdominal magnetic resonance imaging (MRI) was performed in a 56-year-old man during the follow-up of an adrenal adenoma. Incidentally a renal tumor at the upper pole of the left kidney was diagnosed and was suspected of being a renal cell carcinoma. After partial nephrectomy a NET measuring 4.2 cm in diameter could be diagnosed histologically. An extrarenal primary tumor was ruled out by a postoperative gallium 68-tetraazacyclododecane tetraacetic acid-octreotate (68Ga-DOTATATE) positron emission tomography/computed tomography (PET/CT) scan. A primary NET of the genitourinary tract is rare and less than 100 cases have been reported in the medical literature.
