Kortikal nefrokalsinozis

Özet

Kortikal nefrokalsinozis, böbrek korteksindeki kalsiyum birikimidir. BT'de korteks periferinde ince lineer kalsifikasyonlar görülebilir. Kortikal nefrokalsinozis, vasküler hasara bağlı kortikal nekrozla ilişkili olabilir.

Faz ve pencere

Kontrastsız tanısal

Korteks periferinde ince lineer kalsifikasyonlar görülebilir; bu örüntü tramvay izi olarak adlandırılır ve vasküler hasara bağlı kortikal nekrozu düşündürebilir.

Önerilen pencereler: Batın (G 400 / M 50), Yumuşak doku (G 400 / M 40).

BT bulguları

• Böbrek parankiminin dış kısmında, kortekse yerleşmiş yüksek atenüasyonlu kalsifikasyonlar izlenir.
• Kortikal kalsifikasyonlar böbrek parankiminin dış kısmında gözlemlenebilir.
• Kortikal nefrokalsinozis, vasküler kompromise ikincil renal iskemiyle ilişkili olabilir.
• Uzun süreli hastalık süreçlerinde böbrek parankiminde incelme ve atrofi gözlenebilir.
• Kortekste ince lineer kalsifikasyonlar görülebilir ve bu örüntü vasküler hasara bağlı kortikal nekrozu düşündürebilir.
• Kortikal ve medüller nefrokalsinozis aynı hastada birlikte bulunabilir; dağılım her iki bölge için ayrı ayrı tarif edilmelidir.

Normalde

Normal böbrekte korteks, dış konturu çevreleyen ve medüller piramitlerden daha yüksek yumuşak doku atenüasyonlu sürekli bir parankim bandıdır; kontrastsız BT'de içinde yoğun kalsifikasyon çizgileri bulunmaz. Kortikal ve medüller nefrokalsinozis birbirinden farklı parankimal bölgelerde lokalize olabilir.

Ayırıcı tanı

Medüller nefrokalsinozis

kalsifikasyonlar kortikal dış şeritte değil, piramitlerin içindedir.

Renal kalkül

odak parankim içine gömülü kortikal hat yerine kaliks, pelvis veya üreter lümeninde yer alır.

Vasküler kalsifikasyonlar renal arter ve ven boyunca izlenebilir.

Kalsifiye renal kitle veya kist

kalsifikasyon, fokal bir kist duvarı ya da solid kitle tipi bulguyla ilişkili olabilir.

Tuzaklar

• Kalsifikasyonun tek kesitte kortekse komşu görünmesiyle yetinmeyin; dağılımını kortikal ve medüller yerleşimi ayırt edecek şekilde değerlendirin.
• Tramvay izi örüntüsü renal korteksteki ince lineer kalsifikasyonları tanımlar ve vasküler hasara bağlı kortikal nekrozu düşündürebilir; nadiren glomerülonefritle de ilişkili olabilir.

Kendini dene

1. BT görüntülerinde kalsifikasyonların yerleşim yeri ayırıcı tanı açısından önemlidir. Kortikal nefrokalsinoziste kalsifikasyonlar nerede bulunur?

   • Böbrek korteksinde
   • Renal pelvis ve kaliks lümeninde
   • Medüller piramitlerde
   • Renal arter ve ven duvarlarında
   Cevabı göster

   Böbrek korteksinde. Kortikal nefrokalsinoziste kalsiyum birikimi parankimde, kortekste yer alır; renal kalikslerdeki ayrı taşlardan farklıdır.

2. Nefrokalsinozisin temel patolojik özelliği nedir?

   • Böbrek parankiminde kalsiyum tuzlarının birikmesi
   • Kontrast maddenin geçici tutulumu
   • Toplayıcı kanal kistlerinin konjenital genişlemesi
   • Fokal lezyon duvarında kireçlenme
   Cevabı göster

   Böbrek parankiminde kalsiyum tuzlarının birikmesi. Nefrokalsinozis, kalsiyum tuzlarının böbrek parankiminde birikmesidir.
