Abstract

Amaç: Adrenal kortikal karsinomun (AKK) Bilgisayarlı Tomografi (BT) görüntüleme özelliklerini araştırmak.

Gereç ve yöntem: Patolojik olarak AKK tanısı almış 15 hastanın (K/E: 8/7, ortanca [aralık]: 53 yıl [31-74 yıl]) kalitatif ve kantitatif BT bulguları retrospektif olarak değerlendirildi. Lezyonların fonksiyonel durumlarına klinik notlardan ulaşıldı.

Bulgular: Hastaların patolojik tanısı cerrahi (n=12) veya cerrahi eşliğinde biyopsi (n=3) ile konulmuştu. 9 lezyon (%60) fonksiyonel, 6 lezyon (%40) non-fonksiyoneldi. Fonksiyonel lezyonların 5’i androjen, 4’ü kortizon üretmekteydi. Kalitatif değerlendirmede 13 lezyon (%93) nekroz, 3 lezyon (%20) kalsifikasyon ve 1 lezyon (%7) makroskobik yağ içeriyordu. Lezyonların tamamı iyi sınırlı olup heterojen kontrastlanmaktaydı. Lezyonların ortanca (aralık) boyutu 9,7 cm (6.3-18 cm) idi. Prekontrast, arteriyel faz, portal faz ve geç faz ortanca (aralık) dansite değerleri sırasıyla şöyleydi: 34 HU (22-41 HU), 46 HU (27-65 HU), 60 HU (29-90 HU), 48 HU (28-64 HU). 9 hastada 15. dakika geç faz elde olunmuştu. Ortanca (aralık) mutlak (MKYY) ve bağıl (BKYY) kontrast yıkanma yüzdeleri sırasıyla şöyleydi: %48,8 (%-3.8-62.5) ve %21 (%-1.5-30.8). Sadece bir lezyonun MKYY değeri %60’in üzerindeydi.

Sonuç: AKK’lar BT’de genellikle büyük (>6cm), iyi sınırlı, heterojen kontrastlanan, nekrotik kitleler şeklinde görülür. Makroskobik yağ ve kalsifikasyon içerebilir ve geç faz imajlarda sınırlı kontrast yıkanması gösterirler.

Sayın editör, ‘Adrenal Kortikal Karsinom’da Bilgisayarlı Tomografi Görüntüleme Bulguları’ başlıklı makalemi Genel Tip Dergisi’ sistemine yüklüyorum. Bu makalede nadir görülen Adrenal Kortikal Karsinom’un Bilgisayarlı Tomografi görüntüleme bulgularını araştırdık. Daha önce literatürde bildirilmemiş olan kontrast yıkanma yüzdelerini raporladık. Araştırmamızın tamamı veya bir kısmi daha önce başka bir dergide yayınlanmamıştır. Değerli vaktinizi ayırdığınız için şimdiden teşekkür ederim.

Abstract

Objective: To evaluate computed tomography (CT) imaging manifestations of adrenocortical carcinomas (ACC).

Materials and Methods: Qualitative, and quantitative CT findings of 15 patients (Eight women, seven men; median age [range], 53 years [31-74 years]) with 15 pathologically proven ACCs were retrospectively analyzed. Lesions' functional status were captured through clinical notes.

Results: Pathologic diagnosis was based on either surgery (n=12) or surgical biopsy (n=3). Nine lesions were functioning (60%, androgen [n=5] or cortisol [n=4]) and 6 lesions were non-functioning (40%). In qualitative CT analysis, 13 (93%), 3 (20%), and 1 (7%) lesion had necrosis, calcification and macroscopic fat, respectively. All lesions showed well-defined borders and heterogeneous enhancement. Median [range] density on precontrast, arterial phase, portal phase, and 15-minute delay phase were 34 HU (22-41 HU), 46 HU (27-65 HU), 60 HU (29-90 HU), and 48 HU (28-64 HU), respectively. Nine patients had 15-minute delay phase available. Median (range) absolute and relative percentage of enhancement wash-out (APEW and RPEW) values were 48.8% (-3.8-62.5%) and 21% (-1.5-30.8%). Only one lesion had an APEW above %60.

Conclusion: ACCs usually manifest as, large (>6cm), well-defined, heterogeneously enhancing, necrotic masses on CT. These lesions may include calcification or macroscopic fat and tend to show limited wash-out on delay phase CT.
