CT and MR Imaging Manifestation of Adrenal Hemangioma: A Case Report

腎上腺血管瘤在電腦斷層攝影及磁振造影之表現:病例報告

摘要


腎上腺血管瘤非常罕見,我們報告一病例病理證明為腎上腺血管瘤。超音波看到一混合回音的左腎上腺腫瘤,電腦斷層發現一個周邊顯影而中心低密度的腫瘤。磁振造影確定為一左腎上腺腫瘤,呈現出T1低訊號,T2高訊號且在注射完顯影劑後呈現出周邊高訊號。雖然腎上腺血管瘤非常罕見,當一病人發現有腎上腺腫瘤,有上述影像學的表徵時,應將腎上腺血管瘤列入鑑別診斷。

並列摘要


A 63-year-old female suffered from pain over left upper quadrant of abdomen. Ultrasound examinations disclosed a heterogeneous echogenic lesion measuring 6x6 cm, at the upper pole of the left kidney. Non-contrast computed tomography (CT) scan revealed a left suprarenal tumor with low attenuation but peripheral enhancement of this lesion was shown after administration of contrast medium. Magnetic resonance (MR) imaging confirmed the tumor mass arising from the left adrenal gland with progressive centripetal enhancement after administration of contrast medium. After tumor resection, the pathologic result was an adrenal hemangioma.
